Abstract This study characterized Pokkali-derived quantitative trait loci (QTLs) for seedling stage salinity tolerance in preparation use marker-assisted breeding. An analysis of 100 SSR markers on 140 IR29/Pokkali recombinant inbred lines (RILs) confirmed the location Saltol QTL chromosome 1 and identified additional QTLs associated with tolerance. Analysis a series backcross near-isogenic (NILs) developed to better characterize effect locus revealed that mainly acted control shoot Na + /K...
This article describes the development of Multi-parent Advanced Generation Inter-Cross populations (MAGIC) in rice and discusses potential applications for mapping quantitative trait loci (QTLs) varietal development. We have developed 4 multi-parent populations: indica MAGIC (8 parents); plus parents with two additional rounds 8-way F1 inter-crossing); japonica Global (16 - 8 japonica). The used creating these are improved varieties desirable traits biotic abiotic stress tolerance, yield,...
Abstract Salinity tolerance in rice varies with the state of growth, seedling and reproductive stages being most sensitive. However, association between tolerances at two is poor, suggesting that they are regulated by different processes genes. Tolerance stage crucial as it determines grain yield. An F 2 mapping population was developed from genotypes contrasting tolerance: Cheriviruppu Pusa Basmati 1 (PB1). highly tolerant stage, while PB1 sensitive both stages. One hundred thirty‐one...
Abstract Rice, with its wide geographic distribution extending from 50° N to 35° S , is expected be the most vulnerable cultivated crop future changing climates. Among different abiotic stresses, extreme temperatures coinciding critical developmental stages, increasingly frequent floods and drought spells, worsening sea water inundation are some of major threats sustainable rice productivity. Following successful implementation molecular marker‐assisted backcrossing introgress large‐effect...
Salinity tolerance in rice, like other glycophytes, is a function of cellular ion homeostasis. The large divergence homeostasis between the salt-tolerant FL478 and salt-sensitive IR29 rice varieties can be exploited to understand mechanisms salinity tolerance. Physiological studies indicate that shows lower Na+ influx, reduced translocation shoot, maintains Na+:K+ ratio. To basis these differences, comparative investigation transcript regulation roots two cultivars was undertaken. This...
Traditional rice varieties harbour a large store of genetic diversity with potential to accelerate improvement. For long time, this maintained in the International Rice Genebank has not been fully used because lack genome information. The publication first reference Nipponbare by Genome Sequencing Project (IRGSP) marked beginning systematic exploration and use for research breeding. Since then, served as assembly many additional genomes. recently completed 3000 Genomes together public...
In the present study, a total of 53 promising salt-tolerant genotypes were tested across 18 salt-affected diverse locations for three years. An attempt was made to identify ideal test and mega-environments using GGE biplot analysis. The CSSRI sodic environment most discriminating location in individual years as well over could be used screen out unstable salt-sensitive genotypes. Genotypes CSR36, CSR-2K-219, CSR-2K-262 found Overall, CSR-2K-262, CSR-2K-242 superior stable among all with...
Regaining the agricultural potential of sodic soils in Indo-Gangetic plains necessitates development suitable salt tolerant rice varieties to provide an entry for other affordable agronomic and soil manipulation measures. Thus selection high yielding across a range is central. Evaluation breeding lines through on-station on-farm farmers' participatory varietal (FPVS) resulted identification short duration (110-115 days), disease resistant salt-tolerant genotype 'CSR-89IR-8', which was later...
Salt stress is the second most devastating abiotic after drought and limits rice production globally. Genetic enhancement of salinity tolerance a promising cost-effective approach to achieve yield gains in salt-affected areas. Breeding for challenging because genetic complexity response plants salt stress, as it governed by minor genes with low heritability high G × E interactions. The involvement numerous physiological biochemical factors further complicates this complexity. intensive...
Introduction: Soil salinity poses a severe threat to rice production, resulting in stunted growth, leaf damage, and substantial yield losses. This study focuses on developing an early maturing seedling stage tolerant variety by integrating conventional breeding methods with marker assisted (MAB) approaches. Methods: Seedling-stage tolerance Quantitative Trait Locus (QTL) “Saltol” from the salt-tolerant parent FL478 was introduced into high-yielding but salt-sensitive ADT 45. achieved through...
