Genetic variability and correlation studies in wheat (Triticum aestivum L)*

Thirty wheat cultivars were evaluated during rabi seasion of 1998–99 under agro-c1imatic conditions of western Uttar Pradesh (India). Among the characters studied plant height, number of tillers plant⁻¹, ear length, 1000 grain weight and yield plant⁻¹ exhibited higher values of variability. Flag leaf area showed moderate heritability value (65.6%) for better sink development. Grain yield was positively correlated with 1000-grain weight and harvest index. Numbers of grain ear-1 were found to be negatively correlated with 1000-grain weight, harvest index, and flag leaf area. While it was positively correlated with seed and straw yield, suggesting significant effect of number of grains ear⁻¹ on grain yield of wheat.
