Resumo

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.
