Description t-8738
The present investigation was carried out to study the growth, flowering, fruiting, yield
and physico-chemical attributes of seventy mango hybrids belonging to full-sib families of
Amrapali x Sensation and Amrapali x Lal Sundari along with their parents maintained at the
Division of Fruits and Horticultural Technology, I.A.R.I., New Delhi during 2010 to 2011.
Variation in quantitative traits among hybrids and their parents was estimated. The hybrids
derived from cross of Amrapali and Sensation were comparatively taller and had more tree
spread and canopy volume than the hybrids derived from ‘Amrapali x Lal Sundari’ in all age
groups. Leaf characters of hybrids from both crosses also showed wide variation. The full-sib
hybrids (Amrapali x Sensation) had more variation in leaf characteristics than full-sib family
derived from Amrapali x Lal Sundari. Similarly, flowering characteristics of mango hybrids
derived from different full-sib families also showed significant variation. None of the hybrids
exhibited very early panicle emergence i.e., before 10th February. However, hybrids belonging
to full-sib family of Amrapali x Sensation showed early panicle emergence in comparison to
hybrids of Amrapali and Lal Sundari, which showed medium to late panicle emergence. The
proportion of hermaphrodite flowers in hybrids belonging to Amrapali x Lal Sundari cross was
comparatively higher than hybrids derived from Amrapali x Sensation cross. Hybrids and
parent cultivars differed significantly for flowering duration, which ranged between 8.75 to
20.20 days.
Wide range of variability was observed among the hybrids for different physicochemical
characteristics. All 70 mango hybrids and three parental cultivars matured during 10-
20th July. The hybrids evolved from the cross Amrapali x Sensation produced average fruit
weight higher than hybrids derived from parentage Amrapal’ x Lal Sundari. The pulp
percentage ranged from 58.16% to 75.65% and majority of the hybrids gave higher fruit pulp
percentage than their male parents. Parental cultivar Sensation had fibrous on stones but 70%
hybrids belonging to full-sib family obtained from Amrapali x Sensation cross produced either
fibreless or scanty fibrous on stone. Mango hybrids and their parents showed significant
differences for peel thickness and 41.45 per cent hybrids had peel thickness more than
Amrapali. Hybrids of Amrapali x Sensation cross had longer shelf-life than those from
Amrapali x Lal Sundari cross. The hybrids had intermediate total soluble solids, acidity and
total carotenoid contents in comparison to their parents. Interestingly, none of the hybrids
belonging to two full-sib families had higher total carotenoid content than the seed parent
Amrapali. The peel a* value of hybrids evolved from the cross Amrapali x Sensation exhibited
41
higher values than hybrids of Amrapali x Lal Sundari. The pulp a* value also showed
variation in hybrids derived from Amrapali x Sensation and it showed greater variation than
hybrids derived from Amrapali x Lal Sundari. Present results suggest that the quantification of
traits would be of great help to identify the promising mango hybrids for domestic as well as
overseas markets, assist in selection of potential parents for their further utilization in mango
improvement programmes and ascertaining the segregation of traits in the biparental hybrid
progenies.
