Assessment of genetic variability and heritability in Lycopersicon esculentum Mill

Various parameters of genetic variability were estimated for number of flowers/ plant, number of fruits/plant, number of days for fruit setting and yield/plant in tomato (L. esculentum). The variation between the accessions, on the basis of coefficient of variability was greater in traits like numbe...

Description
Summary:Various parameters of genetic variability were estimated for number of flowers/ plant, number of fruits/plant, number of days for fruit setting and yield/plant in tomato (L. esculentum). The variation between the accessions, on the basis of coefficient of variability was greater in traits like number of fruits/plant (13.92%) followed by number of flowers/plant with coefficient of variability (10.75%) and yield/plant (9.99%). Broadsense heritability was highest for number of fruits/plant (96.56%) followed by number of flowers/plant (93.45%) reflecting the effectiveness of selection in the present germplasm of tomato improvement.
