摘要：

A recombinant inbred line (RIL) population derived from the cross between Pusa1266 (a new plant type) with Jaya (a popular indica rice variety) was used for mapping QTL associated with grain physico-chemical and cooking quality traits in rice. A total of 310 recombinant inbred lines were evaluated for nine grain physico-chemical and cooking quality traits at two locations in India, during Kharif 2007. A linkage map based on 135 molecular markers was developed and a total of 22 QTL associated with seven traits, namely brown rice percentage, milled rice percentage, kernel length before cooking, kernel breadth before cooking, length/breadth ratio, kernel length after cooking and kernel breadth after cooking on seven different chromosomes were identified by composite interval mapping. Pusa1266 allele contributed positively at 14 loci whereas Jaya contributed at 8 loci. Nine QTL influencing five different traits were identified with an R-2 > 10%. A marker interval RM18222-HvSSR05-39 on chromosome 5 influencing two traits (qKBBC5-1, qLBR5-1) across the locations was identified. This locus can be used for fine mapping and identification of the candidate gene for these traits.
