Abstract
Potato is the most widely grown non-grain crop and ranks as the third most significant global food crop following rice and wheat. Despite its long history of cultivation over vast areas, slow breeding progress and environmental stress have led to a scarcity of high-yielding potato varieties. Enhancing the quality and yield of potato tubers remains the ultimate objective of potato breeding. However, conventional breeding has faced challenges due to tetrasomic inheritance, high genomic heterozygosity, and inbreeding depression. Recent advancements in molecular biology and functional genomic studies of potato have provided valuable insights into the regulatory network of physiological processes and facilitated trait improvement. In this review, we present a summary of identified factors and genes governing potato growth and development, along with progress in potato genomics and the adoption of new breeding technologies for improvement. Additionally, we explore the opportunities and challenges in potato improvement, offering insights into future avenues for potato research.

Mohanraj J, Subramanian KS, Yuvaraj M. Nano-fibre matrix loaded with multi-nutrients to achieve balanced crop nutrition in greengram (Vigna radiata L.). PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2024; 207:108369. [PMID: 38241830 DOI: 10.1016/j.plaphy.2024.108369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 01/07/2024] [Accepted: 01/11/2024] [Indexed: 01/21/2024]
Abstract
This research paper focuses on exploring the possibility of delivering macro, micro and trace elements using seed encapsulation through nano-fibres that are known to improve the nutrient use efficiencies while reducing the loss of nutrients. The nano-fibres were developed using an electrospinning machine by subjecting the polymer solution (10% polyvinyl alcohol PVA) loaded with recommended quantities of nutrients under optimal solution (pH, concentration, viscosity) and process (voltage, flow rate, tip-to-collector distance) parameters. The nano-fibres were characterized using SEM, TEM, FT-IR, XRD, TGA and Impedance spectra besides nutrient release pattern by ICP-MS. The data have clearly shown that nano-fibres retained nutrients and released slowly up to 35 days. After the characterization, green gram (Vigna radiata L) seeds were encapsulated with nano-fibres loaded with multi-nutrients and each seed was coated with approximately 20-25 mg of nano-fibres, dibbled into the soil and the physiological, nutritional, growth and yield responses were assessed. Seeds encapsulated with nano-fibres fortified with nutrients (NF) had registered significantly higher crop emergence percentage (C 62%; NF 99.8%), root length (C 12.3; NF 27.1 cm), shoot length (C 28.7; NF 47.7 cm), dry matter production (C 16.2; NF 27.5 g) and grain yield (C 621.6; NF 796.3 kg ha-1). All the parameters measured in nano-fibre encapsulated seeds fortified with 100% of recommended dose of nutrients (NF) were higher than uncoated control (C) seeds but comparable with 100 % conventional fertilizer applied ones (RDF). Such phenomenal increase in growth and yield parameters associated with the extensive surface area of nano-fibres that is capable of retaining and releasing nutrients in a regulated pattern and assist in improving the pulses productivity by achieving balance crop nutrition which alleviating multi-nutrient deficiencies.
