Source material for accelerated breeding of new commercial varieties of spring soft wheat

Abstract

The aim of the studies based on the modeling of hybrid genotypes of spring wheat is to study collection varieties of various origin at several test sites, different in soil and climatic conditions, in order to identify the best of them with high adaptive potential. Hybrids created using the set of limiting traits of varieties distinguished in three test points were involved in the biotechnological process to obtain dihaploid forms in order to accelerate the breeding process. Based on them, a new source material has been created. Using the optimized method of haploproducer Z.mays on the basis of a hybrid combination (Visa x Amir), the new variety of spring soft wheat Lisa was created, with a yield potential of 7.5-8.0 t/ha, resistant to lodging, meeting quality requirements in terms of quality to strong wheat. The variety is recommended for cultivation in 2 (North-West), 3 (Central) and 7 (Middle Volga) regions of the Russian Federation.
