METHODS TO ASSESS TRITICALE FORMS USING A COMPLEX OF COMPUTER PROGRAMS

Abstract

Resulting from spring triticale breeding research under conditions of West Siberian forest-steppe areas near the Ob for the period of 2009–2013, a computer database containing information on productivity, product quality, resistance to diseases and pests, and other traits was formed. The initial material for breeding were intervarietal hybrids of hexaploid-based spring triticale derived from diallel crossings among the four spring triticale varieties from the collection of the N.I. Vavilov Research Institute of Plant Industry (Sokol Kharkovskiy, Ukro, Gabo, K-3881) as well as these varieties with Sirs 57 cultivar of winter triticale bred at the Siberian Research Institute of Plant Production and Breeding. A model of software algorithmic complex on triticale breeding was experimentally developed. Complex operation results allowed us to evaluate collection samples and select parental forms of spring triticale for hybridization when developing breeding material with a required combination of economic characters. The use of the software algorithmic complex made it possible to select the following initial forms of spring triticale: line K-3881 having the maximum value of total combining ability as to the trait of “the number of kernels per main spike”; intensive variety K-3881; plastic variety Ukro of the extensive type, which gives stable high yields under different conditions, and Sirs 57 x Ukro combination of breeding value.
