Studies on Genetic Variability for some Economic Traits in <I>Solanum viarum</I> Dunal

Abstract

A study of base population of Solanum viarum Dunal and fifteen selections made from it has been undertaken. A wide range of variability was observed for days to flower, number of berries and yield/plant in the base population. Selections were made for earliness and yield and coefficient of variability, heritablity and genetic advance has been studied in them. The highest genotypic variance was observed for yield/plant and lowest for solasodine content. Heritability was high for all the characters except for solasodine content. Genetic advance was high for yield/plant followed by number of berries/plant and moderate for plant spread, solasodine content and plant height. High heritability coupled with moderate to high genetic advance and genotype coefficient of variability was observed for yield/plant, number of berries/plant, plant spread and plant height.
