Abstract

Purpose. Studying the inheritance of such trait of soybean (Glucine max (L.) Merrill) as growing season length in F2 and assessing hybrid combinations to identify more quick-ripening phenotypes as compared to parents. Methods. Laboratory test, mathematico-statistical evaluation. Results. In most crossbreeding combinations, when parents differed by growing season length, late ripeness was dominated in F2, in one combination – early ripeness, in two combinations, when parents scarcely differed by growing season length, complementary effect was observed for this index. It was found that ‘Anzhelika’/‘Mageva’ combination generated the highest number of more quick-ripening forms than any of the parents (13.1%), a smaller number was identified in ‘Legenda’/‘Vizhion’ (6.4%) and ‘Anzhelika’/‘Gentleman’ (4.0%), and barely noticeable number was observed in ‘Legenda’/‘Yelena’ combination (1.3%). Conclusions. In the following crossbreeding combinations as ‘Legenda’/‘Vizhion’, Legenda’/‘Korado’, ‘Legenda’/‘Ustia’, ‘Legenda’/‘Yelena’, ‘Yug-30’/‘Gentleman’, ‘No. 894’/‘Vizhion’, ‘Anzhelika’/‘Annushka’, ‘No. 894’/‘Annushka’, ‘Legenda’/‘Annushka’, ‘No. 441’/‘Gentleman’, ‘No. 441’/‘Vizhion’, ‘No. 441’/‘Annushka’, ‘Anzheli­ka’/‘Gentleman’ and ‘Anzhelika’/‘Prypiat’ when parents considerably and insignificantly differ by growing season length, late ripeness was dominated in F2. ‘Ustia’/‘Vizhion’ and ‘Yug-30’/‘ Vizhion’ crossbreeding combinations in which parents hardly differ by growing season, complementary effect was observed in F2 for this index.
