Analysis of Sudangrass collection cultivars in the Cis-Ural steppe of the Bashkortostan Republic

Abstract

This paper reports on a study of 62 collection cultivars of Sudangrass evaluated by economic traits for 4 years to create new source material for the Sudangrass selection of higher nutritional value adapted to the Cis-Ural steppe. The research revealed some highly productive and early-maturing Sudangrass cultivars for selecting new varieties highly adaptive to local agro-climatic conditions. Early ripening varieties Chishminskaia ranniaia, Yaktash, Demskaia, Smena, Novosibirskaia 84, Lira had 81-85 days of the interphase period from full sprouts to complete seed ripeness. Highly productive Anastasia, Aiusha, Zernogradskaia 576, and Alexandrina varieties had a fresh yield of more than 41.9 t/ha. Demskaia, Anastasia, Alexandrina, Aiusha had good nutritional qualities of fresh yield (with 10.04 – 10.51% protein and 7.80 – 10.01% sugar in dry matter): In 2017, the State Variety Testing of a new Sudangrass cultivar Demskaia started. The middle-early Sudangrass variety Demskaia has an average yield of 47.1 t/ha of green mass, 8.14 t/ha of absolutely dry matter, and 2.59 t/ha of seeds.
