Abstract

Two intervarietal substitution lines of common wheat cv. Sava bearing chromosome 5B from Saratovskaya 29 and Diamant 2 donors and two near-isogenic lines (NILs) of winter cv. Bezostaya 1 with the Vrn-B1 locus from the same donors were developed. Multiple allelism of the dominant Vrn-B1 locus was studied in these lines. It manifested itself as earing time variation in plants grown near Novosibirsk (West Siberia), Almaty (Kazakhstan), and in a greenhouse. One dominant allele, Vrn-B1S, having a stronger effect on earing time, was detected in Saratovskaya 29 and another, Vrn-B1Dm, in Diamant 2. The NILs and substitution lines are late-ripening. Lines with Vrn-B1S come to earing earlier than with Vrn-B1Dm.
