Research of a spring soft wheat collection material based on ear’s structure and grain quality elements

In modern conditions of high intensification of agriculture, the key task at all stages of development is to increase the volume of grain produced. This requires constant improvement of the varietal composition of production fields. When creating a new variety, it is necessary to comprehensively study the collection nursery for parental forms of important elements of grain structure and quality. In these scientific studies, 32 varieties of spring soft wheat were studied at the Institute of Seed Production and Agricultural Technologies in the Ryazan region. Standard variety Agata. From the studied varieties, the following varieties were identified: by the length of the ear Arsei, Margarita, Simbirtsit, Uralosibirskaya, Darnitsa, which are 19.5–31.2% higher than the standard, by the number of grains KVS Torridon, KVS Aquilon, Margarita, Ethos, Ekada 70, Odeta, and Kinelskaya Otrada, Uralosibirskaya, Darnitsa, Hercules exceeds the standard by 5.29–36.77%, by weight of grain per ear KVS Akvilon, KVS Torridon, Odeta, Margarita, Simbirtsit, Kalispero, Mary, Hercules, Uralosibirskaya, Ethos, Darnitsa, Kinelskaya Otrada, Kazan Yubileinyaya with indicators above the standard by 1.88–20.63%, in terms of protein content in grain Zlata, Novosibirskaya 29, Uralosibirskaya, Siberian Alliance, Sable, Chelyaba 2 above the standard by 0.42–2.01%, according to the gluten content in grain Novosibirskaya 29, Sable, Chelyaba 2 is 2.5–3.2% higher than the standard; by weight of 1000 grains Odeta, Siberian Alliance, Margarita, Simbirtsit, Burlak is 2.5–3.2% higher than the standard.
