<i>VIGNA RADIATA</i> SAMPLES TEST IN THE MIDDLE VOLGA CONTINENTAL ENVIRONMENTS
The purpose of researches - is theoretical and practical justification of mash bean's introduction in ecological conditions of the Middle Volga. This culture is versatile in use: as food, feed, green manure and medicine. The seeds are used in food as cereals, green beans and etiolated shoots - as vegetables, green herbage is dried, ensiled and plowed into the ground (green manure), straw and chaff are fed to the cattle. Average harvest of the gain is 10-16 hwt per 1 hectare, green mass - up to 200 hwt per 1 hectare. Mung beans and its products are well assimilated by human organism. When Vigna radiata L. (R) Wilczek is used to eat almost not observed meteorism. Starch from mash has low glycemic index. That is especially important for people with diabetes. This high-protein culture contains all the essential amino acids in sufficient quantities. It also has B group vitamins, PP vitamin (nicotinic acid), C vitamin (ascorbic acid) and other important organic and mineral nutrients. This is a valuable crop for the available diet food. 60 Vigna radiata L samples have been examined represented by the collection of Russian Crop Science Institute. According to the methodological instructions of this Institute, characteristics of the clones within the specific climatic conditions, their drought tolerance and productivity were grown and developed. The year of the study is considered as extreme draught conditions for crops, resulted in obtaining much more adequate and numerous Vigna radiata L specifications within described climatic environment and soil moisture less. Thus with a potential yield of 8-19 dt/ha (hundreds kilograms per hectare) with a satisfactory weight of 1000 seeds and the length of the growing period 70-110 days. These samples к-12208 (India), к-617558 (China), к-617653 (China), к-617654 (China), к-617566 (China), к-617578 (China), к-617582 (China), к-617584 (China) able to adapt to weather and climatic conditions of the region, can be considered as the initial base for the selection within the Middle Volga Area.
