Accelerating haploid induction rate and haploid validation through marker-assisted selection for qhir1 and qhir8 in maize. FRONTIERS IN PLANT SCIENCE 2024; 15:1337463. [PMID: 38504887 PMCID: PMC10948437 DOI: 10.3389/fpls.2024.1337463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 02/19/2024] [Indexed: 03/21/2024]
Abstract
Doubled haploid (DH) technology becomes more routinely applied in maize hybrid breeding. However, some issues in haploid induction and identification persist, requiring resolution to optimize DH production. Our objective was to implement simultaneous marker-assisted selection (MAS) for qhir1 (MTL/ZmPLA1/NLD) and qhir8 (ZmDMP) using TaqMan assay in F2 generation of four BHI306-derived tropical × temperate inducer families. We also aimed to assess their haploid induction rate (HIR) in the F3 generation as a phenotypic response to MAS. We highlighted remarkable increases in HIR of each inducer family. Genotypes carrying qhir1 and qhir8 exhibited 1 - 3-fold higher haploid frequency than those carrying only qhir1. Additionally, the qhir1 marker was employed for verifying putative haploid seedlings at 7 days after planting. Flow cytometric analysis served as the gold standard test to assess the accuracy of the R1-nj and the qhir1 marker. The qhir1 marker showed high accuracy and may be integrated in multiple haploid identifications at early seedling stage succeeding pre-haploid sorting via R1-nj marker.

Combining ability of tropical × temperate maize inducers for haploid induction rate, R1-nj seed set, and agronomic traits. FRONTIERS IN PLANT SCIENCE 2023; 14:1154905. [PMID: 37113598 PMCID: PMC10126284 DOI: 10.3389/fpls.2023.1154905] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 03/23/2023] [Indexed: 06/19/2023]
Abstract
In vivo maternal haploid induction in isolation fields is proposed to bypass the workload and resource constraints existing in haploid induction nurseries. A better understanding of combining ability and gene action conditioning traits related to hybrid inducers is necessary to set the breeding strategy including to what extent parent-based hybrid prediction is feasible. This study aimed to evaluate the following in tropical savanna in the rainy and dry seasons for haploid induction rate (HIR), R1-nj seed set, and agronomic traits: 1) combining ability, line per se, and hybrid performance of three genetic pools; 2) genetic parameters, the modes of gene action, and heterosis; and 3) the relationships of inbred-general combining ability (GCA) and inbred-hybrid performance. Fifty-six diallel crosses derived from eight maize genotypes were evaluated in the rainy season of 2021 and the dry season of 2021/2022. Reciprocal cross effects including the maternal effect barely contributed to the genotypic variance for each trait observed. HIR, R1-nj seed set, flowering dates, and ear position were highly heritable and additive inherited, while ear length showed dominant inheritance. The equal importance of additive and dominance effects was found for yield-related traits. Temperate inducer BHI306 was the best general combiner for the HIR and R1-nj seed set, followed by two tropical inducers, KHI47 and KHI54. The ranges of heterosis were trait-dependent and slightly influenced by the environment, where hybrids in the rainy season consistently had higher heterosis than those in the dry season for each trait observed. Both hybrid groups derived from tropical × tropical and tropical × temperate inducers showed taller plants, larger ear size, and higher seed sets than the corresponding parents. However, their HIRs were still below the standard check of BHI306. The implications of genetic information, combining ability, and inbred-GCA and inbred-hybrid relationships on breeding strategies are discussed.

Variation in anthocyanin pigmentation by R1-navajo gene, development and validation of breeder-friendly markers specific to C1-Inhibitor locus for in-vivo haploid production in maize. Mol Biol Rep 2023; 50:2221-2229. [PMID: 36564657 DOI: 10.1007/s11033-022-08214-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Accepted: 12/13/2022] [Indexed: 12/25/2022]
Abstract
BACKGROUND In-vivo maternal haploids serve as the basis of doubled haploid (DH) breeding in maize. R1-navajo (R1-nj) gene governing anthocyanin colouration in the endosperm and embryo is widely used to identify haploid seeds. However, the expression of R1-nj depends on genetic-background of source-germplasm used for deriving DH-lines. Further, presence of C1-Inhibitor (C1-I) gene suppresses the expression of R1-nj, thus makes the selection of haploids difficult. METHODS In the present study, 178 subtropically-adapted maize inbreds were crossed with two R1-nj donors 'that do not have haploid induction genes'. Of these, 76.4% inbreds developed purple colour in endosperm, while 23.6% did not show any colouration. In case of scutellum, 62.9% inbreds possessed colour and 37.1% were colourless. The anthocyanin intensity varied greatly, with 19.66% and 42.98% inbreds displayed the least intensity, while 16.85% and 0.84% inbreds showed the highest intensity in endosperm and scutellum, respectively. Two C1-I specific breeder-friendly markers (MGU-CI-InDel8 and MGU-C1-SNP1) covering (i) 8 bp InDel and (ii) A to G SNP, respectively, were developed. MGU-CI-InDel8 and MGU-C1-SNP1 markers predicted presence of C1-I allele with 92.9% and 84.7% effectiveness, respectively. However, when both markers were considered together, they provided 100% effectiveness. CONCLUSIONS These markers of C1-I gene would help in saving valuable resources and time during haploid induction in maize. The information generated here assume great significance in DH breeding of maize.

Seasonal Variation of Tropical Savanna Altered Agronomic Adaptation of Stock-6-Derived Inducer Lines. PLANTS (BASEL, SWITZERLAND) 2022; 11:plants11212902.

Abstract
Tropicalization is one of the major objectives in breeding haploid inducers to address the poor adaptation of temperate haploid inducers in doubled haploid production in tropical maize. Gaining a better understanding of weather profiles in targeted agroecology is important. This study aimed to investigate the seasonal variation of tropical savanna climate and its impact on agronomic traits and haploid induction rate (HIR) of Stock-6-derived haploid inducer lines. A total of 14 haploid inducers were evaluated across two typical growing seasons between 2020 and 2021. Weather data were collected on daily minimum and maximum temperatures, relative humidity, precipitation, and solar radiation whereas phenotypic data were recorded on plant phenology, tassel attributes, plant stature, ear components, inducer seed rate (ISR), and HIR. The effects of season, genotype, and genotype by season were significant for all traits except season factor on ISR. Seasonal variation existed where the dry season was more suitable for haploid induction and inducer maintenance, as haploid inducers revealed better agronomic performance and seed set, delayed flowering dates, and higher HIR. Since the crossover performance of haploid inducers over seasons was detected, further implications on genotype selection in each season are discussed.
