A NEW SOYBEAN VARIETY SibNIIK 9 FOR SIBERIA, URAL AND MIDDLE VOLGA REGIONS
Abstract
A new soybean variety SibNIIK 9 has been obtained by repeated individual selection from the progeny seeds of the initial variety SibNIIK 315 processed by cobalt-60 gamma radiation in a dose of 50 gray. Breeding research was conducted from 1999 to 2016 in Novosibirsk Region. Some soybean lines obtained by the biotechnology methods, somaclonal variation and recurrent in vitro regeneration, were studied at the same time. The in vitro induced mutagenesis and somaclonal variability methods in combination with multiplied individual selection have proven to be effective in producing new soybean varieties with valuable traits: early maturity, high seed productivity, higher attachment of the lower bean, improved chemical composition of grain. The resulting cultivars have higher level of ontogenetic adaptation, including resistance to unfavorable hydrothermal factors and pathogens. The new soybean variety SibNIIK 9 is not inferior to the standard SibNIIK 315 in earliness, and exceeds it in grain yield on average by 220 kg/ha. The growing period under conditions of Novosibirsk Region lasts 82 to 107 days; the height of attachment of the lower bean is more than 12 cm. The new cultivar is resistant to lodging of stems and pods cracking, and exceeds the standard in resistance to leaf bacteriosis and fusariosis as well as in fat and protein contents in grain. There is a patent for a selection achievement. Resulting from the State variety trials, the variety SibNIIK 9 has been included on the State Register of Breeding Achievements, and permitted for use in Middle Volga, Ural, West Siberian and East Siberian regions of the Russian Federation since 2017.
