The cultivars showed significant variability with respect to tree, foliage and inflorescence characters. Pusa Arunima showed the maximum plant height (2.23 m) and crown spread (2.02 m) while Amrapali had the minimum height (1.33 m) and crown spread (1.48 m) among all the cultivars. The maximum leaf length, leaf width and leaf area were recorded in Pusa Shreshth (24.02 cm, 6.14 cm and 118.35 cm2 respectively) while these were the minimum in Pusa Surya (20.35 cm, 4.67 cm and 83.63 cm2 respectively). Significant variations were recorded among the cultivars for various inflorescence characters. The longest and the shortest panicle was recorded in Pusa Lalima (35.99 cm) and Pusa Surya (19.92 cm) respectively. Pusa Arunima showed the maximum percentage of hermaphrodite flowers (47.92%). The maximum fruit retention was recorded in Pusa Shreshth (16.21%) while Pusa Arunima showed the least fruit retention (7.46%). Initial number of fruits set per panicle, number of hermaphrodite flowers, leaf width and leaf area showed a positive and significant correlation with fruit retention. Initial number of fruit set per panicle showed the maximum direct positive effect on fruit retention.EnglishThesis
