  Description

  Correlation interrelations of some morpho¬logical signs of winter wheat and their influ¬ence on productivity are established. Positive correlation communication of efficiency with weight of grain with an ear (r=0,70) is revealed

  CREATION OF INITIAL MATERIAL FOR BREEDING OF WINTER WHEAT VARIETIES TOLERANT TO SMUT

  06.00.00 Agricultural sciences

  Description

  The key task of the agriculture in Russia is the further improvement of grain production. Thus, prevention of losses of winter wheat yields because of the diseases remains relevant. The significance of varieties tolerant to diseases, especially to smut (fungus) is of primary importance. Therefore, it’s essential to create initial material for breeding of the varieties tolerant to smut. According to the results of the trials with artificial infection with pathogens, among the samples of winter wheat there have been identified varieties belonging to different groups of tolerance to smut. They are a highly sensitive cultivar ‘к-69361’ (Korea), a sensitive variety ‘Izyuminka’ (Russia), moderately sensitive variety ‘Asket’ (Russia) and almost tolerant variety ‘1621/03’ (Russia). We studied the reaction of the hybrids F2 on infection with smut in different variants of hybridization to obtain stable progeny. The correlation between the number of infected plants in parent and hybrid (F2) populations have been considered. The productive tillering of the plants has been determined in all variants of the trials; it was the least one on the plants with 100% of infected leaves. The hybrids F3 and F 4 have been distributed according to the degree of their tolerance to smut. For further work we have selected the lines with practical resistance to smut (fungus)
