Abstract

This study provides a comparative assessment of the obtained hydrides with their parent varieties in terms of yield, marketability, and phenological observations in the conditions of the Northern forest-steppe of the Tyumen region. This line of experiments is carried out to study the resulting hybrids and select parent forms to obtain more productive breeding material. Completely different and contrasting varieties of Adretta have been selected for the parent forms. Cornflower. In the 350 seeds were obtained from crossed plants, 39 promising hybrids were selected from them. When comparing hybrids with parental forms, on average, 41% of hybrids were equal or had higher yields compared to the maternal form (Adretta variety), and 36% of hybrids were close to the paternal form (Cornflower variety). A significant number of hybrids, 23%, had low yields and were culled. 13% of hybrids had high yields: AB 58/14 (35.24 t/ha), AB 51/10 (31.91 t/ha), AB 50/7 (28.23 t/ha), AB 69/11 (27.26 t/ha), AB 54/8 (26.3 t/ha). According to a number of characteristics, the resulting hybrid material is equally divided along the maternal or paternal line, of the total number, only 1 hybrid had an excess of parental forms in yield.
