Abstract:

In the present investigation lentil genotypes; one macrosperma (IPL-406) and the other microsperma (HUL-57) were subjected to drought stress at mid-vegetative, flower-initiation and pod-formation stages by withholding irrigation. We observed that drought stress of various phenophases significantly decreased shoot length (8% - 22%), leaf area (23% - 52%), CMS (26% - 58%) and phenological developments (0 - 14 DAS) but increased root length (14% - 63%) of plants. Pre anthesis accumulated biomass and nitrogen within the plants parts viz. roots, leaves, stem and pod walls and its efficient allocation to growing seeds serves as major sources during active pod filling periods. A significant negative relationship was observed between parameters like leaf area with RWC (R2 = 0.845*), CMS (R2 = 0.473*) and GMP (R2 = 0.876*), shoot length with GMP (R2 = 0.206*) under drought stress. Meanwhile a significant positively relationship was found between RWC and CMS (R2 = 0.503*) under drought. Drought indices such as higher DTE and GMP values are proposed to be the selection traits in lentil breeding programme for drought prone environmental conditions. It is suggested that pod formation stage fallowed by flower initiation stage is more sensitive to drought than mid vegetative stage. Genotype HUL-57 was drought resistant and IPL-406 was drought sensitive.
