【 摘 要 】

Six pure lines of maize were tested in a randomized complete block design with three replicationunder irrigated and rainfed conditions. Genetic variation was found between the genotypes for yieldpotential (Yp) stress yield (Ys), tolerance index (TOL), geometric mean productivity (GMP),harmonic mean (HM) and stress tolerance index (STI). Stress tolerance index was corrected using acorrection coefficient (Ki) and thus a modified stress tolerance index (MSTI) was introduced as theoptimal selection criterion for drought-tolerant genotypes. The results of three-D plotting indicatedthat the most desirable genotype for irrigated and rainfed conditions was the genotype K1515, fornon-stressed conditions K18 and for stress conditions K104/3, K760/7 and K126/10.
