Characterization of twenty pummelo genotypes

Abstract

Abstract : A study was conducted at the pummelo orchard of RARS, BARI, Akbarpur, Moulvibazar and laboratories of BSMRAU during September, 2007 to October, 2009 with 20 pummelo genotypes comprising BARI Batabi Lebu-1 as check variety to characterize and select superior genotype(s). It is noted that tree shape, growth habit, plant and leaf characters varied in the genotypes. Flowering initiated in middle of December and lasted upto second week of April. Flower characters also varied. In most cases, it took 240 days from flowering to harvest. The genotype CG-5 produced maximum (113.7) and CG-134 had minimum (15.3) numbers of fruits/plant. CG-12 and CG-24 obtained the haviest (1261.5g) and the lowest (552.4g) fruit weight, respectively. CG-18 obtained the toomost yield/plant (81.5kg) followed by CG-5 (81.0 kg), CG-12 (61.0 kg) and CG-185 (60.1 kg), respectively. CG-1 (10.0%), CG-4 (9.3%), CG-18 (12.0%), CG-20 (10.0%), CG-151 (9.5%) and CG-185 (10.2%) had equal or more TSS than the check (9.3%). Number of seeds per fruit ranged 23-148. Weight of 100 seeds differed from 19.0 to 49.7g. However, CG-1, CG-4, CG-10, CG-18, CG-20, CG- 134, CG-151 and CG-185 were found better in respect of yield, pulp colour, pulp texture, pulp firmness, weight of pulp, juiciness, juice content, taste, bitterness and TSS as compared to check.
