DescriptionThe 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
