Morpho-Phenological Characterization and Yield Attributes of Different Primary Mango (Mangifera indica L.) Genotypes Under Bihar Condition

Mango (Mangifera indica) is one of the most important tropical fruit crops cultivated across the world, including India. Morphological and phenotypic variations among the existing cultivars are essential parameters for assessing the genetic diversity of any crop for their further use in any systematic breeding programme. In this experiment, twenty five mango genotypes were assessed for different morpho-phenological attributes. Maximum male flower (95.51%) was recorded in G-37 genotype while maximum hermaphrodite flower (17.38%) with highest fruit retention (50.00%) was observed in G-03 genotype. However, highest sex ratio (31.83) was calculated in G-22 followed by G-11 (22.08) genotypes. The highest fruit set per panicle (8.00) was registered in G-18 followed by G-22 and G-12 genotypes. Consequently, maximum number of fruits per plant (140.00) was recorded in G-18 followed by G-22 (125.00). While maximum peel, pulp and stone weight were noticed in G-44 with highest pulp: stone ratio (7.27) in G-12 genotypes. Accordingly, the results of the present investigation recommends that G-18 and G-22 are the best suited genotypes for their utilization in the future mango breeding programme for improving the yield of the hybrids under the environmental conditions of Bihar, India.
