Comparative performance of fifteen papaya genotypes

Abstract

Performance of fifteen papaya genotypes was studied at the Regional Agricultural Research Station, Ishwardi, Pabna during 2010-2011. Wide range of variabilities was found among the fifteen genotypes. The highest plant height and base girth were exhibited in the genotype PP-38 (131.67cm) and (21.67cm). Moreover, the lowest plant height and base girth were also exhibited in local genotype (111.67cm) and PB-14 (16.33cm). Genotype PB-18 produced the maximum number of fruit per plant (48.0) where as the minimum (10.00) was in PRO-23. The highest yield (89.82t/ha) was obtained from PB-18, which was statistically differed from the other genotypes. The lowest yield (28.00 t/ha) was produced by local genotype. The genotypes PP-36 (81.50 t/ha), PJ-22 (66.32 t/ha), PP-31 (65.80 t/ha) and PB-14 (57.57 t/ha) also showed good yield performance. The PB-38 had the maximum TSS(14%), which was statistically identical to PB-18 (13.6%), and it was closely followed by PP-36 (12.25%). The minimum (6.59%) TSS was recorded from ISD-002, which was statistically similar to local (7.0%).
