Growth, flowering and yield attributes of full-sib (Amrapali × Sensation) hybrids of mango

The present investigation was carried out to study the growth, flowering and yield attributes of 50 full-sib mango hybrids belonging to ‘Amrapali’ × ‘Sensation’ cross along with their parents during 2010–2012. The hybrids and their parents showed significant variation for growth, leaf, flowering and yield characters. Results revealed the maximum number of leaves in H-12-8 (48.60), maximum leaf area in H-13-7 (136.82 cm²) and longest petiole length in H-13-4 (5.22 cm). Hybrids such as H-1-10, H-13-1 and H-13-4 had the maximum inflorescence pigmentation (7.00 rating). Maximum number of hermaphrodite flowers per panicle was observed in H-1-1 (362.48), whereas male flowers were maximum in H-2-9 (1499.50). However, the maximum sex ratio was noted in H-3-5 (0.94). The longest flowering duration was obtained in H-1-14 (20.68 days). Maximum fruit weight was recorded in H-1-5 (315.43 g) and yield in H-1-1 (44.25 kg/tree). This study would be of great helpful in selection of potential parents for their further utilization in mango improvement programmes.
