The created hybrids with new lines and testers
were studied in 2014-2015, in the conditions of
the central zone of the Krasnodar region and the
Central Black Earth Region (Voronezh and
Belgorod regions). As a parent forms for
selection of early ripening and Medium early
corn hybrids there were used lines of various
groups of ripeness of the ident heterosis group:
Kr 714 Kr 740 Kr 757 Kr 651 Kr and 602. All of
these lines had high combining ability, and the
line 602 Cr was used as a donor for a quick return
of moisture from the grain when ripening. With
the participation of the lines from the collection
of the Institute and the donor line, we have
created four hybrid combinations on the basis of
which, the selection was received by the five-year
selection of new source material for breeding new
hybrids of corn. The assessment of comutiny
capacity of new lines was performed using a linetesters
of the genetic institute collections of
721MV Cr, Cr 801MV, Kr 654 Kr 244MV, Cr
602MV, Kr and Kr 802MV 752. Lines testers
were represented by a heterosis group of
Lancaster, Stiff Stalk Synthetic and wide lines
with a genetic basis. According to the guidelines
of the State strain testing of crops, and as a result
of the field experiment, we have calculated the
energy savings for new early maturing corn
hybrids in comparison with the standard ones.
Saving energy for equivalent fuel from new
hybrids of corn comparing to the standard for 1
ha of crop was due to their grain productivity and
varied depending on the conditions of the
Voronezh region from 81.4 to 101.5 kg, in the
Krasnodar region it was 79,0-97,9 kg
In the article, we show the results of researches on creation of a material with a fast return of moisture at ripening of a grain are resulted. The general (ACS) and specific (SCS) combinational ability of new corn lines was determined. A promising material has been identified for further work in the field of rapid release of moisture to grain during maturation
In this article, we have considered water-yielding ca-pacity of maize grain in the dynamics of its gestation. The researches in this direction allowed to identify the lines and hybrids with quick-impact moisture and longer period of gestation
The article reveals the issues concerning the results of the research of estimation of new early lines of maize with quick grain dry down in two areas of growing. The regression analysis which based on derived data identified intensive hybrids and the most sustainable hybrid combinations by yield and harvesting moisture of grain
