QUANTITATIVE AMINO ACID ANALYSIS OF SEEDS FROM COMMON BEAN UNIVERSITY COLLECTION

Current study is concentrated on the abundance of Kazakhstan food as heirloom beans and pumpkins varieties and lines based on the extending germplasm including domestic as international accessions and specimens received from Asian countries, European sources, Russia, Turkey and USA. A range of introduced common bean varieties have indicated high seed germination and maturation rates as well as resistance to water deficit, whereas domestic varieties have been demonstrated to surpass certain foreign accessions and varieties by seed weight and other seed parameters. Data on bean collection, grown in steppe and mountain zones of Almaty region presented in that paper are completed by quantitative and qualitative amino acid evaluation. Domestic and external varieties and lines (cvs “Aktatti”, “Bijchanka”, “Zuzka”, “Camelia”, “Katka”, “Luna”, “Nazym”, “Red Goya”, “Talgat” and “Ufimskaya”) have been clustered by using the data on amino acid composition of bean seeds analized by liquid chromatography. Essential amino acids have been shown to achieve 27.5 – 29. 8% of total amino acids content in domestic lines. Apparently, Lys-Thr couple of essential amino acids known to be significant for plant growth. If tyrosinylation index (Phe/Tyr ration) for local lines is around 0.91 – 0.94, similar index for external varieties is of 0.88-0.89. Thus, it may mean that local lines contain membrane proteins possessing complex (mechanic, thermal and chemical) stability when compared with international bean analogues under investigation. By the content of individual amino acids (Glu, Asp, Ala and Pro) domestic bean lines have been shown to exceed external varieties 2.0-2.4 times.
