Figure 2. UPGMA cluster analysis showing the diversity and relationship among 75 landraces of rice based on 145 alleles generated by 32 SSR markers. Super-basmati, IR6 and JP5 indicated in circles.Group I (C = Cluster, SC= Sub Cluster)) C1: cluster 1 (cold tolerant, short grained genotypes), C2: cluster 2 (early maturing, tall height, medium seed length, zone II), Group II C3: cluster 3 (Three Sub clusters(SC): SC1: Early maturing Zone III, SC2: Non-Basmati type, SC3: Basmati type) C4: Cluster 4 (Japonica type landraces from northern areas).
