Protein profile study in bittergourd (Momordica charantia L.)

The protein profile study in bitter gourd (Momordica charantia L.) was carried out at G.B.PANT Univ. of Agric & Tech., Pantnagar. Composite seed samples collected from 17 genotypes (6 indigenous &11F1s) grown under polyhouse condition were utilized for total seed protein electrophoresis. Similarity coefficient among 6 parents ranged from 0.27 to 0.93 with the divergence ranging from 7 to 73%. Cluster dendrogram constructed using UPGMA method showed two main clusters. Parents PBIG-4 & Kalyanpur Baramasi was distantly related with PBIG-2, PBIG-1, Kalyanpur Sona and Priya White. So any one of each cluster can be used for developing heterotic hybrid among the members of other clusters. Similarity co-efficient between two lines were approximately 0.38, whereas similarity coefficient between two main clusters was 0.27 (divergence73%).
