Studies on fruit growth pattern, fruit drop and maturity of ber genotypes under tarai conditions

The present investigation was conducted at Pantnagar with an objective to investigate the fruit growth pattern, fruit drop and maturity of ber genotypes. The experiment comprised of twenty four treatments of ber genotypes arranged in Randomized Block Design with two replications. The results showed that fruit length and fruit diameter were higher in cv. Noki and Sanaur 3, while, minimum was recorded with Illaichi and Chhuhara, during November to December, respectively. Maximum fruit length and diameter were recorded with Sanaur 6 and Umran while minimum was recorded with Nazuk during January to February, respectively. Maximum fruit drop was observed with ZG 2, followed by IIaichi, Kala Gola and Sanaur 6 and minimum with Sanaur 3. Cultivars of ber can be classified into three groups viz. early, medium and late group, based on maturity. Cultivar Rohtaki Gola in early maturity group, ZG 3 in mid maturity group and Umran in late group were found to be promising cultivars for cultivation in tarai areas.
