Influence of Moisture Stress on Root Traits and Yield Components of Mungbean Genotypes

A field experiment was conducted at the experimental field twelve Mungbean (Vigna radiata L.) genotypes under water stress condition. A wide diversity among the genotypes in their root characters including yield was recorded. Genotypes varied from genotypes TBG-104, KU-12-13 root length was increased during moisture stress condition in both the years. But genotypes showed lower amount of root dry weight, pod dry weight along with number pods per plant and number pods per cluster in irrigated control as well as moisture condition. TBG-104, KU-12-13, KU-12-37, LBG-645recorded significantly more root length, root and pod dry matter, pods per plant and pods per cluster under both irrigated as well as stress conditions, which denotes the ability of these genotypes in sustaining the higher root length and absorb the water from deeper layers of soils. Whereas NDU-12-300 and LBG- 680 recorded lowest total dry matter during rabi 2015-16 and rabi 2016-17.
