Breeding value of varieties of soft spring wheat on grain quality

Abstract

The results of study 180 collection samples of soft spring wheat of different ecologi-cal and geographical origin according to the grain quality are given. Variability of grain quality depending on the cultivar and growing conditions is given. The greatest variability for years was marked in such indicator as gluten content in grain (Cv=4,2–20,5 %), the smallest – grain nature (Cv =0,3-4,9%). The highest variability of the values of the geno-typic coefficients of variation have vitreousness and quality of gluten in grain (Cv=11,9-14,1%; Cv=14,2-18,3%), the lowest one in grain nature (Cv=3,9-6,4%). The most valuable source material for soft spring wheat breeding is Novosibirskaya 91, Annet, Tarskaya 10, Biryusa, Ekaterina, Duo Chernozemya, Granit.
