Abstract : The highest number of fruits per tree and yield of fruits (kg/tree) was recorded in Pottalma and the lowest number of fruits per tree and yield of fruits (kg/tree) were observed in Kalepad and Mulgoa, respectively. In respect of biochemical characters, the highest TSS was recorded in Himayuddin and the lowest TSS was recorded in Neelum. The highest acidity and ascorbic acid content were recorded in Kalepad and the lowest in Baneshan and Mulgoa, respectively. By the application of clustering technique, the twelve genotypes were grouped into four clusters. Among the four clusters, cluster I was the biggest one, consisting of six genotypes and cluster II contained four genotypes, while cluster three and four had one genotype each. Among sixteen traits studied, number of fruits per tree and yield in kg showed higher degree of phenotypic and genotypic coefficient of variation. In correlation studies, yield per tree, plant height, tree spread and tree girth had high correlation with yield.
