Utilization of plant genetic resources for the improvement of temperate fruit crops

Published on

The Himalayas provide suitable ecological niches for the
prevalence of large number of temperate fruit germplasm.
Seven crab apples (Malus baccata) have been collected
from the region and evaluated for horticultural traits. Crab
apple from Shillong has been found to possess a high
level of resistance against powdery mildew than M. zumi.
Its performance as root stock and resistance to woolly
aphid is much superior to standard clonal root stocks M9
and MM106. It is compatible with all commercial apple
varieties and produces semi-vigorous tree suitable for high
density plantation. Wild pear (Pyrus pashia var. Kumaonii)
possesses desirable traits like good propagation potential
and recommended for root stock in root rot infested areas.
Wild kiwi fruit (Actinidia spp.) is small sized and non hairy
type which could be utilized for the improvement of
existing varieties. It can be used as desirable rootstock.
The region also inhabits many Prunus species and
indigenous edible temperate fruits, which could be
exploited for commercial traits. An unique walnut has been
collected which bear fruits both terminally and laterally
and therefore, it could be utilized for high density planting.
