COMPARATIVE EVALUATION OF PRODUCTIVITY INDICATORS OF DOMESTIC AND FOREIGN SOYBEAN VARIETIES IN THE CONDITIONS OF THE ALMATY REGION

Abstract

 This article presents a comparative study of six Kazakhstan-bred soybean varieties (Victory, Pamyat YGK, Lastochka, Aisaule, Zhansaya, Yelmerey) and 19 foreign varieties (Delta, Slavia, Selecta 301, Vilana, Korsak, Galina, Trijumf, Voyevodzhanka, Sava, Ascacubi, Hilario, Blamcos, Atlantic, Luna, Safrana, Santana, Sponsor, Zen, Dekabig) conducted at an ecological variety testing nursery. Among the Kazakh varieties, Yellmerey, Zhansaya, and Aisaule stood out for their high yields of 49.2 c/ha, 48.5 c/ha, and 47.3 c/ha,   respectively. The top-yield foreign varieties were Voyevodzhanka from Serbia with 48.8 c/ha, Sava with 49.0 c/ha, Luna from Italy with 51.8 c/ha, and both Atlantic and Blamcos with 46.0 c/ha each. The French variety Sponsor also achieved a high yield of 51.7 c/ha. The Kazakh variety Aisaule and Italian variety Luna were notable for their high fat content at 21.9% and 22.2%, respectively. Varieties such as Victory and Aisaule from Kazakhstan, along with Delta, Selecta 301, and Vilana from Russia, Korsak from Ukraine-Canada collaboration, and Safrana from France, exhibited high protein content ranging between 38.6% and 40.6%. These outstanding varieties serve as a breeding resource for developing new, high-yield soybean varieties for the southeastern region of Kazakhstan.
