SPRING SOFT WHEAT SAMPLES WITH VALUABLE CHARACTERISTICS

Abstract

In the field of the Institute of seed production and agricultural technology, branch of FEDERAL state budgetary scientific institution FNAC VIM on dark-gray forest soil by conventional methods in 2014-2018 comparative evaluation of 40 samples of spring wheat competitive variety trials. On average over five years valuable features stood out the eight that exceeded the standard cultivar Agata by 0.27 to 1.24 t/ha. Maximum yield of formed samples 416-08Н52 and 260-05Н2101, respectively, and of 7.54 and 7.33 t/ha, which exceeded the standard variety of agate of 2.63 and 1.78 t/ha, respectively. The identified group of samples 260-05Н2101, 539-10Н163, 1036-09Н21, 898-09Н125, which had an average excess of 14.9...of 25.4 % over the zoned varieties for the Central region. In our studies, the coefficient of variation of yield on samples was 7.6...30.0 %. The lowest coefficient of variation observed in cultivars: Zlata (Cv of 7.6 %), Agate (Cv 12.9 %), in RIMA (Cv of 13.7 %), the samples 1664-09Н66 (Cv 13.1 percent) 898-09Н125 (Cv of 13.5 %), 918-10Н259 (Cv of 15.5 %). It was found that the determining factor in the formation of high yields in competitive variety testing is the total bushiness (r=+0.83), the number of productive ears per unit area (r=+0.63) and the number of grains in the ear (r=+0.38). Highest number of productive stems per unit area formed lines 185-07Н29, 260-05Н2101, 918-10Н259, 1036-09Н21 – 537 562...PCs/m2. Most ear grain content (32...34 PCs) had samples 918-10Н259, 539-10Н163, 898-09Н125, variety of RIME. A large proportion of samples (75 %) exceeded the standard grade of agate by weight of grain per ear by 4.4...27.2 %. A negative relationship between the yield and the mass fraction of crude gluten in grain r= -0.55 was revealed. The high gluten content in Ternei least its a variation on godammit samples 185-07Н29, 898-09Н125, Zlata, 1036-09Н21.According to the data obtained greatest practical value, are the samples 918-10Н259, 539-10Н163, 898-09Н125.
