The indices of sorghum seed quality in dependence on ecological and geographical origin

Abstract

Abstract The current paper presents the study results of protein percentage, content of lysine and starch in the collection samples of grain sorghum of various ecological and geographical origin. It was determined that the seed protein percentage in the grain sorghum samples varied from 9.0 to 13.5%. The highest values were identified in the samples from Russia (KiM, Krymbel, Krusta, Ros’), Ukraine (Pioner 412/Milovskoe 6, No. 13-13, Pioner 878/Genicheskoe brown 129) and China (KX 8, No. 26-14) with 13.0-13.5%. The lysine content in protein of the studied samples was 2.5-4.3%, while the value of the standard variety Zernogradskoe 88 was 3.17% with the standard deviation of 0.24%. The maximum content (3.8-4.3%) was identified in the samples Early Hegari (Peru), Line ExF3 IS12606 (Australia), DN-35f (Ukraine), CS-175 (Philippines), H.S.-21 (Romania), Sorghum k-9553 (Korea). The starch content in seed of the collection samples varied within 70.2-77.5%. The highest intragroup values were showed by the samples from Peru (73.9%), Australia (73.8%), France (73.0%), Senegal (73.4%).
