PERFORMANCE OF ALMOND GERMPLASM UNDER HIGH HILL TEMPERATE WET ZONE OF HIMACHAL PRADESH
Main Article Content
Abstract
Almond cultivation in high hill temperate wet zone of Himachal Pradesh is
attributed mainly to green almond marketing. Sixteen almond cultivars which were
introduced at Temperate Horticultural Research Station, Kotkhai (National Hortorium)
from 1961 to 1968 were evaluated for their growth, flowering, yield and resistance
to insect, pest and diseases. Cultivars namely Dhebar, Kashmir Seedling, I. X.
L. and Drake were recorded as vigorous. About 25 per cent twigs of all the
trees showed gummosis, however gum exudation on fruit was very less in
Kashmir Seedling (3.0 per cent). All thin shelled cultivars were highly infested
with gummosis on fruit and nut and kernel rotting was also more prevalent. No
particular relationship exists in bacterial leaf spot and extent of gummosis. Stem
gummosis was more associated with attack of flat headed peach tree borer and
its attack was more serious in varieties introduced from Kinnaur district. Kashmir
. Seedling, IXL.. Drake, Afghanistan Seedling were comparatively less affected
