Inheritance of heading date in crosses of wheat cultivars responsive to light intensity

Fayt V.I., Stelmakh A.F.

 




The inheritance of heading date has been studied in crosses of spring bread wheat cultivars differing in their reaction to various light intensities. The parental cultivars were similar in their Vrn and Ppd gene systems and differed in heading dates. Domination of higher reaction to light intensity has been shown in F1 on duration of ear emergence-heading period. Analysis of F2 populations has shown the identity of earliness per se genetic systems in Novosibirskaya 22 and Ordynskaya cultivars. Digenic differences have been revealed for both these cultivars from Tyumenskaya rannyaya cultivar on duration of ear emergence-heading period.
