BACKGROUND Rice (Oryza sativa L.) is a highly drought sensitive crop, and most semi dwarf rice varieties suffer severe yield losses from reproductive stage drought stress. The genetic complexity of drought tolerance has deterred the identification of agronomically relevant quantitative trait loci (QTL) that can be deployed to improve rice yield under(More)
Fig. 3 Screening of doubled haploids for identification of heterozy-gotes. SSR marker (RM206) differentiating somatic tissue derived heterozygote from doubled haploids (1 BS6444G; 2, 4–21 representatives of doubled haploids; 3 heterozygote and M 50 bp DNA ladder) The online version of the original article can be found under
African wild rice Oryza brachyantha (FF), a distant relative of cultivated rice Oryza sativa (AA), carries genes for pests and disease resistance. Molecular marker assisted alien gene introgression from this wild species to its domesticated counterpart is largely impeded due to the scarce availability of cross-transferable and polymorphic molecular markers(More)
The cytoplasmic male sterile line system comprising CRMS 32A and its maintainer line CRMS 32B is a popular choice for the development of new hybrids in India as CRMS 32A, having Kalinga 1 cytoplasm (other than WA), is a viable alternative to WA cytoplasm. However, both lines are susceptible to bacterial blight (BB), a major disease on rice. As enhancement(More)
A total of 200 doubled haploids (DHs) were generated from an elite rice hybrid, ‘BS6444G’ for which an androgenic method was developed by manipulating the physical and chemical factors. The spike pretreated at 10 °C for 7–8 days was effective for callusing and green plant regeneration. The maximum callus frequency was achieved when the anthers cultured in(More)
Enterprise Resource Planning (ERP) systems, over the years, have evolved into integral business systems in both medium and large organizations. The strength of an ERP is that it is a computerized transactional information system, with a centralized data repository. This allows for significant data availability and seamless collaboration between business(More)
Genetic diversity analysis based on genome-wide single-nucleotide polymorphism (SNP) assay of a set of Indian rice cultivars including modern high-yielding varieties and landraces revealed two broad groups, one with “Aus” and the other with “Indica” cultivars. Marker analysis of these genotypes was carried out for three major drought tolerance QTLs as well(More)
