THE ESTIMATION OF SOYBEAN INITIAL MATERIAL ACCORDING TO GRAIN QUALITY ON HOMEOSTASIS

Résumé

The current paper has presented the homeostatic indicators of protein and oil content in kernels of 43 collection soybean samples from the south of the Rostov region, studied by the Khangildin method (1984). According to the 2016–2018 studies of homeostatic quality indicators of soybean grain, there were identified the samples “K-11305” and “Veselovskaya 3” with a high protein percentage and the samples “K-10943” and “MDT 2” with the highest homeostasis of the protein content in grain. The maximum oil percentage in soybean grain was identified in the varieties “Donskaya 9”, “Natalie”, “Alba”, “Chara” and “MDT 2”. The stress resistance and homeostatic parameters of oil content of these varieties were at an average level in the collection. A high stress resistance and homeostasis of oil content in grain were identified in the varieties “Don 21” (5330.6), “Sigalia” (3376.0) and “VNIIOZ – 1” (2528.6) with seed oil content at an average level in the collection.
