Abstract:
Sixteen guava genotypes were studied for genetic divergence (using Ward’s minimum variance method) on the basis of yield and yield related characters. The genetic variation among genotypes was high enough to divide them into five clusters. Majority of genotypes were grouped in cluster Ⅳ. The cluster Ⅰ showed the maximum intra cluster distance (53864.83) followed by cluster Ⅴ (46774.31) while, the maximum inter cluster D2 values were recorded between clusters Ⅳ and Ⅴ (168563.80). The genotypes belonging to cluster Ⅳ (Allahabad Safeda, Nagpur Seedless, Parkers Dessert, Kohir Safeda, Lalit, Lucknow-49 x Nagpur Seedless) and cluster V (Lucknow-49, VNR-Bihi selection line (ARP)) are genetically more divergent, which indicates that the genotypes in these two clusters are highly heterozygous and are useful in hybridization programme to exploit effective hybrid vigour in future breeding plan.
