Correlation studies in chickpea grown under rainfed and irrigated conditions in northern plains of India

The experimental materials were sown in the research area of Department of Dry land Agriculture and Pulses Section of the Department of Genetics and Plant Breeding, CCS HAU, Hisar during rabi season of 2013-14. The experiment comprised 21 genotypes (including local & national checks) and was grown in 3 replications in a plot size of 8 rows of 4m length with plant-to-plant distance of 10 cm and row to row spacing of 45 cm in dry land area and 30 cm in irrigated area. Observations were recorded on Days to maturity, Plant height at 30, 45, 60 DAS and physiological maturity (cm), Primary branches per plant ,Seed yield per plant (g), Seed yield (g/plot), Rain water use efficiency (kg/ha-mm). The results indicated that days to maturity, plant height and Primary branches per plant recorded positive significant correlations with seed yield per plant under normal sown conditions which were changed in the rainfed areas. These are quite interesting results. The genetic diversity of the material under study is quite evident from the morphological data, The information so gathered will be used to decide the strategy of chickpea improvement for drought environment.
