Abstract
Distant hybridization refers to crosses between two different species, genera, or higher-ranking taxa, which can break species limits, increase genetic variation, and combine the biological characteristics of existing species. It is an important way of creating genetic variation, fertile strains, and excellent characteristics in new strains and populations. Combining analyses and summaries from many inter-related documents in plants and animals, both domestic and international, including examples and long-standing research on distant hybridization in fish from our laboratory, we summarize and compare the similarities and differences in plant and animal distant hybridization. In addition, we analyze and review the biological characteristics of their different ploidy progenies and the possible causes of disparity in survival rates. Mechanisms of sterility in animal and plant distant hybrids are also discussed, and research methods for the study of biological characteristics of hybrids, including morphology, cytology, and molecular cytogenetics are presented. This paper aims to provide comprehensive research materials and to systematically compare the general and specific characteristics of plant and animal hybrids with regards to reproduction, genetics, growth traits, and other biological characteristics. It is hoped that this paper will have great theoretical and practical significance for the study of genetic breeding and biological evolution of plant and animal distant hybridization.

Abstract
Intertribal somatic hybrids between Brassica napus (2n = 38, AACC) and a dye and medicinal plant Isatis indigotica (2n = 14, II) were obtained by fusions of mesophyll protoplasts. From a total of 237 calli, only one symmetric hybrid (S2) and five asymmetric hybrids (As1, As4, As6, As7 and As12) were established in the field. These hybrids showed some morphological variations and had very low pollen fertility. Hybrids S2 and As1 possessed 2n = 52 (AACCII), the sum of the parental chromosomes, and As12 had 2n = 66 (possibly AACCIIII). Hybrids As4, As6 and As7 were mixoploids (2n = 48-62). Genomic in situ hybridization analysis revealed that pollen mother cells at diakinesis of As1 contained 26 bivalents comprising 19 from B. napus and 7 from I. indigotica and mainly showed the segregation 26:26 at anaphase I (AI) with 7 I. indigotica chromosomes in each polar group. Four BC(1) plants from As1 after pollinated by B. napus resembled mainly B. napus in morphology but also exhibited some characteristics from I. indigotica. These plants produced some seeds on selfing or pollination by B. napus. They had 2n = 45 (AACCI) and underwent pairing among the I. indigotica chromosomes and/or between the chromosomes of two parents at diakinesis. All hybrids mainly had the AFLP banding patterns from the addition of two parents plus some alterations. B. napus contributed chloroplast genomes in majority of the hybrids but some also had from I. indigotica. Production of B. napus-I. indigotica additions would be of considerable importance for genome analysis and breeding.

Abstract
The beet cyst nematode (Heterodera schachtii Schmidt) can be controlled biologically in highly infected soils of sugar beet rotations using resistant varieties of oil radish (Raphanus sativus L. ssp. oleiferus DC.) as a green crop. Resistant plants stimulate infective juveniles to invade roots, but prevent them after their penetration to complete the life cycle. The resistance trait has been transferred successfully to susceptible rapeseed by the addition of a complete radish chromosome. The aim of the study was to construct a genetic map for radish and to develop resistance-associated markers. The map with 545 RAPD, dpRAPD, AFLP and SSR markers had a length of 1,517 cM, a mean distance of 2.8 cM and consisted of nine linkage groups having sizes between 120 and 232 cM. Chromosome-specific markers for the resistance-bearing chromosome d and the other eight radish chromosomes, developed previously from a series of rapeseed-radish addition lines, were enclosed as anchor markers. Each of the extra chromosomes in the addition lines could be unambiguously assigned to one of the radish linkage groups. The QTL analysis of nematode resistance was realized in the intraspecific F(2) mapping population derived from a cross between varieties 'Pegletta' (nematode resistant) x 'Siletta Nova' (susceptible). A dominant major QTL Hs1( Rph ) explaining 46.4% of the phenotypic variability was detected in a proximal position of chromosome d. Radish chromosome-specific anchor markers with known map positions were made available for future recombination experiments to incorporate segments carrying desired genes as Hs1( Rph ) from radish into rapeseed by means of chromosome addition lines.

Abstract
Intertribal somatic hybrids of Raphanus sativus (2n = 18, RR) and Brassica rapa spp. chinensis (2n = 20, AA) with the dye and medicinal plant Isatis indigotica (2n = 14, I I) were firstly obtained by polyethylene glycol-induced symmetric fusions of mesophyll protoplasts. One mature hybrid with R. sativus established in field had intermediate morphology but was totally sterile. It had the expected chromosome number (2n = 32, RRI I) and parental chromosomes were distinguished by genomic in situ hybridization (GISH) analysis, and these chromosomes were paired as 16 bivalents in pollen mother cells (PMCs) at diakinesis and mainly segregated equally as 16:16 at anaphase I (A I), but the meiotic disturbance in second division was obvious. Five mature hybrids with B. rapa established in field were morphologically intermediate but showed some differences in phenotypic traits and fertility, two were partially fertile. Cytological and GISH investigations revealed that these hybrids had 2n = 48 with AAIIII complement and their PMCs showed normal pairing of 24 bivalents and mainly equal segregation 24:24, but meiotic abnormalities of lagging chromosomes and micronuclei appeared frequently during second divisions. AFLP analysis showed that all of these hybrids had mainly the DNA banding pattern from the addition of two parents plus some alterations. Some hybrids should be used for the genetic improvement of crops and the dye and medicinal plant.

Abstract
In rape ( Brassica napus), no resistance to the beet cyst nematode (BCN) Heterodera schachtii is available. This study was carried out to determine the specific chromosome(s) of resistant radish ( Raphanus sativus) carrying the gene(s) for nematode resistance as a prequisite to convert rape from a host into a trap crop for this pest. A Raphanobrassica progeny of 25 plants was analyzed which segregated for all nine chromosomes of the Raphanus genome in a genetic background of synthetic rape. The number of radish chromosomes was determined by fluorescence in situ hybridization, using the Raphanus-specific DNA probe pURsN; and their type was identified by chromosome-specific randomly amplified polymorphic DNA markers. Five different multiple rape-radish chromosome additions (comprising the whole set of nine radish chromosomes, a-i) were selected and crossed to rape. For each cross-progeny, the number of cysts on plant roots was counted 42 days after inoculation with a L2 larvae suspension. Simultaneously, the plants were characterized for the presence or absence of individual radish chromosomes, using sets of chromosome-specific markers. Thus, the effect of each radish chromosome on cyst number was tested. Chromosome d had a major resistance effect, whereas the presence/absence of the other radish chromosomes had nearly no influence on cyst number. Plants with added chromosome d showed a resistance level comparable with that of the radish donor parent. The analysis in the cross to rape of a plant monosomic only for chromosome d confirmed the strong effect of this chromosome on nematode resistance. A further experiment comprising seven crosses using winter rape breeding lines and monosomic addition line d as pollen parent provided the same results on a broader genetic basis. In each case, the added chromosome d in a single dosage caused nearly the full resistance of the radish donor. Resistance was independent of the glucosinolate content in the roots. The possibilities for stabilizing BCN resistance in rape and its use for other crops and nematodes are discussed.

Abstract
Intergeneric hybrids of the wild crucifer Diplotaxis catholica (2n = 18, D(C)D(C)) as female with two crop Brassica species, namely Brassica rapa (2n = 20; AA) and Brassica juncea (2n = 36; AABB) as male, were developed, using ovary and sequential culture. Reciprocal crosses were not successful, suggesting unilateral cross incompatibility. Morphologically, the hybrid plants resembled the crop brassica parents, but were nearly male- as well as female-sterile. Induction of amphiploidy helped to improve pollen fertility for the D. catholica x B. rapa cross (73%), but less so for the D. catholica x B. juncea cross (35-40%). Female fertility was also higher in both the amphiploids. Cytological analysis of the F(1) hybrids revealed aberrant meiosis with predominant occurrence of the univalents. Partial genomic homoeology between the A genome of B. rapa and the D(C) genome of D. catholica was indicated by the presence of up to five bivalents in 14.7% of the PMCs in the D. catholica x B. rapa hybrid, and 1-2 trivalents or a quadrivalent in nearly 44% of the PMCs in the derived amphiploid. In the second cross, D. catholica x B. juncea, up to six bivalents and one trivalent were observed indicating homoeology between the A/B genomes of B. juncea and the D(C) genome of D. catholica. The possibility of introgression of desirable genes from D. catholica into crop Brassica species exists in view of significant affinity between the D(C) and A/B genomes.

Abstract
Spontaneous outcrossing of different malesterile rapeseed lines and transgenic hybrids with a population of a weedy species, Raphanus raphanistrum L., has led to the harvest of numerous seeds showing a size dimorphism. Flow cytometry analysis correlated with chromosome counts showed that all of the large seeds belonged to rapeseed, whereas the small seeds were a mixture of mostly interspecific triploid hybrids, with some trigenomic amphidiploids, diploid and haploid rapeseed plants. Significant differences were revealed between the rapeseed lines and transgenic hybrids in their ability to form interspecific hybrids with Raphanus raphanistrum under natural conditions. Resistance to the herbicide Basta was properly expressed in the triploid and amphidiploid hybrids. Low male fertility of the interspecific triploid hybrids was not correlated with seed set in the subsequent generation.

Abstract
Sexual and somatic hybrid plants have been produced between Sinapis alba L. (white mustard) and Brassica napus L. (oil-seed rape), with the aim to transfer resistance to the beet cyst nematode Heterodera schachtii Schm. (BCN) from white mustard into the oil-seed rape gene pool. Only crosses between diploid accessions of S. alba (2n = 24, Sa1Sa1) as the pistillate parent and several B. napus accessions (2n = 38, AACC) yielded hybrid plants with 31 chromosomes. Crosses between tetraploid accessions of S. alba (2n = 48, Sa1Sa1Sa1Sa1) and B. napus were unsuccessful. Somatic hybrid plants were also obtained between a diploid accession of S. alba and B. napus. These hybrids were mitotically unstable, the number of chromosomes ranging from 56 to more than 90. Analysis of total DNA using a pea rDNA probe confirmed the hybrid nature of the sexual hybrids, whereas for the somatic hybrids a pattern identical to that of B. napus was obtained. Using chloroplast (cp) and mitochondrial (mt) DNA sequences, we found that all of the sexual F1 hybrids and somatic hybrids contained cpDNA and mtDNA of the S. alba parent. No recombinant mtDNA or cpDNA pattern was observed. Three BC1 plants were obtained when sexual hybrids were back-crossed with B. napus. Backcrossing of somatic hybrids with B. napus was not successful. Three sexual hybrids and one BC1 plant, the latter obtained from a cross between a sexual hybrid and B. napus, were found to show a high level of BCN resistance. The level of BCN resistance of the somatic hybrids was in general high, but varied between cuttings from the same plant. Results from cytological studies of chromosome association at meiotic metaphase I in the sexual hybrids suggest partial homology between chromosomes of the AC and Sa1 genomes and thus their potential for gene exchange.
