Lablab purpureus: Evaluation and Selection of Drought-tolerant - High-yielding Accessions in Dry Farming Systems Based on Drought Tolerance Indices and Multi-environmental Yield Trials

Knowledge of plant responses to the soil moisture regimes is pre-requisite for drought tolerance studies. The present research study was performed evaluate tolerant indices selection Lablab genotypes able tolerate early Terminal Moisture Stress (TMS). three evaluation sites from different agro-ecological conditions were selected this study. Each site consisted two trials with stress-free (MSF) and TMS conditions. designs experiments comprised a randomized complete block design. twelve accessions used in best former screening experiment at seedling stage. Data collections included seed yield plant-1 MSF quantified through ten developed whose correlation coefficients (significant* @ p=0.05, ** p=0.01 5%) computed mean under both Based on analysis, indices; MP, GMP, STI discovered higher (> 0.5), effective selecting high based combined rank method desirable all sites. Through method, D147, D363, HA4, D349, D352, D348, D359 generally as across We therefore, suggest farmers' above-selected their fields before releasing them commercial varieties.
