RFLP Analysis of Genomic Regions Associated with Resistance to Preharvest Sprouting in Wheat

Resistance to preharvest sprouting (PHS) is difficult to incorporate into new varieties because heritability is low and selection is limited to one generation per year. Our objective was to identify genomic regions containing quantitative trait loci (QTL) associated with resistance to PHS in two recombinant inbred (R) populations of white wheat (Triticum aestivum L. em. Thell.) by restriction fragment length polymorphism (RFLP) markers. One population consisted of 78 RI lines from the cross of NY6432-18 (NY18) × «Clark's Cream» (CC). The second population consisted of 138 RI lines from the cross between sib lines NY18 and NY6432-10 (NY10) (.)
