General mean for all the nine quantitative characters were observed to be higher under low plant density when compared to high density planting. Phenotypic coefficient of variation was found to be high in closer spacing than in wider spacing except for plant spread. The genotypic coefficient of variation was also higher at closer spacing for all the characters except for the characters like number of main branches per plant and number of flowers per plant. Higher heritability values were observed for plant spread and flower weight of closer spacing when compared to the wider spacing. Except the flower size and flower weight, all other characters were found to be positively correlated with yield under close spacing. At wider spacing, characters like days to flower, plant height, number of lateral branches per plant and number of flowers per plant showed significant positive correlation with yield.
