Morphological and Physiological Performance of Indian Soybean [Glycine max (L.) Merrill] Genotypes in Respect to Drought

Background: Soybean is a key crop that grants an imperative supply of oils and proteins to humans and animals; however, its productivity spectacularly diminished owing to the occurrence of drought stress. Methods: The present investigation was executed during Khalif 2018-2019 to recognize drought tolerant genotypes on the basis of an array of morpho-physiological traits. Morpho-physiological analysis among 53 genotypes divulged the existence of drought tolerance capability in studied genotypes. Result: On the basis of current findings, it can be concluded that drought stress retards the growth and metabolic activity of soybean genotypes. These parameters showed considerable amount of variability under drought stress at different growth stages in soybean. Among 53 soybean genotypes, four genotypes viz., JS97-52, AMS 2014-1, RVS-14 and NRC-147 was found to be drought tolerant.
