Correlation between Different Morphological Traits of Pomegranate (Punica grantum)

Abstract

Pomegranate is quite popular among consumer for its striking, sweet acidic taste and refreshing arils. Pomegranate is one of the ancient fruit crops which were originated in Iran. Total 151 pomegranate genotypes along with their hybrid parents (Bhagwa, DF, Nana) combinely 154 used for morphological characterization. Total 13 morphological parameters were used for characterization and Analysis of Variance, mean comparison and simple correlations were analysed. Significance differences (P<0.05) were found among all the genotypes of pomegranate. Highest critical differences at 5% were 13.21 (Fruit weight), 11.98 (Aril %), 2.552Thorn [No/Shoot length (m)] recorded and lowest in leaf blade width 0.143, 0.145 in leaf blade length, 0.456 in fruit length and 0.48 in seed hardiness respectively. Plant growth parameters, leaf parameters and fruit parameters are significantly correlated to each other. Fruit weight and seed hardiness was negatively correlated to each other (r= -0.42). Those fruit have larger size and weight have less seed hardiness. Fruit characteristics are negatively correlated with leaf characteristics (r= - 0.22).The largest the leaf size smallest the fruit size.
