Abstract

They are given the results of the study of new early-ripening and mid-early hybrids of corn for grain according to the main economic characteristics: grain yield and harvesting moisture of the grain on two backgrounds - dry land and irrigation in the Volgograd region. The main indicator of the hybrid value  was the figure of the breeding index. As a result of studies, it was found out that the productivity of corn hybrids increases sharply under irrigation conditions, in comparison with the bogara it is higher by 75–85%, and in dry years by 100% or more. Harvesting grain moisture of hybrids during irrigation is always higher. Due to the high grain yield, the breeding and economic value of hybrids on irrigation in any test year is higher than on the bogara. According to the data in the early ripening group on the bogara, the breeding index was 2.4; under irrigation it was 3.4; in the mid-early group - 2.5 and 3.6, respectively. The best hybrids were selected for transmission to the Testing of New Varieties and further implementation in production: in the early ripening group: WG 3, WG 4, WG 5, in the mid-early one: RS 5, RS 6, RS 8.
