The significant climate changes observed and registered throughout the entire world over the past few years demonstrate the vital importance of finding workable solutions allowing us to preserve our natural resources (especially vegetal genetic resources, land, and water) and ensure a steady and nutritious food supply to all people. The use of genotypes with drought and salinity tolerance, which are resistant to pathogens and have minimum inputs, might represent an alternative solution to the current challenges. The aim of this study was to test a species – the mung bean - that has all the above characteristics, and to recommend its use to farmers. The mung bean is distinguished by its high protein content, and it is appropriate for human consumption. The study was accomplished using a number of 96 genotypes. The paper presents data for 22 representative genotypes of (Vigna radiata (L.) Wilczek). The vegetation period for the genotypes involved in the study varied from 85 to 110 days. Our study revealed the fact that variety influenced: germination, emergence duration, interval to appearance of first true leaves, flowers and pods, plant height, number of fertile shoots, number of pods per plant, pod length, number of seeds in pods, and weight of 100 seeds production of grain. The mean value per hectare in relation to the mung bean’s productive potential was 1.88 t ha-1. The sprouting capacity highlighted a full germination process in 2-3 days, and a necessary minimum of 4-5 days to develop sprouts 5 cm in length. During our investigation, we discovered that the genotypes with the highest seed weight value had a faster rate of sprouting. Our TLC investigation concluded that the mung bean can be considered a fooddrug due to its chemical composition. Correlation and path coefficient analyses indicated that high yielding mung bean genotypes could be obtained by selecting plants with a high number of pods per plant. The cultivation of Vigna radiata (L.) Wilczek species can contribute to the development and diversification of agricultural production through diversification of food in general and the development of sustainable agriculture in the context of European and world agriculture.
