Mapping of QTL associated with heading time in winter wheat

The duration of periods to heading has been investigated for 107 winter wheat cultivars of different origins. To reveal the DNA markers to QTL associated with the heading rate, the cultivars and individual plants of the F 2 progeny from a cross between the Omskaya Ozimaya and Numbu Komugi cultivars,...

Summary:The duration of periods to heading has been investigated for 107 winter wheat cultivars of different origins. To reveal the DNA markers to QTL associated with the heading rate, the cultivars and individual plants of the F 2 progeny from a cross between the Omskaya Ozimaya and Numbu Komugi cultivars, which contrasted most in respect of the analyzed trait, have been analyzed by SSR-PCR. Two revealed loci— Xgwm512 and Xgwm429 —explain 19.3% (8.9% and 10.4%, respectively) of all differences in the duration of periods to heading, which were observed in individual F 2 plants under field conditions.
