Estimates of combining ability are useful in determining the value of watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) lines in producing new hybrids with high yield and better quality. This research was conducted to estimate the general and specific combining abilities and heterosis in five inbred lines proposed for watermelon breeding at the University of Guilan, Iran. Analysis of variance indicated significant differences among hybrids for fruit weight and number of branches per plant. The highest specific combining ability (SCA) for the fruit weight was associated with the cross An × S. The cross S × Red had the highest SCA for the number of lateral branches. The high-parent heterosis was higher in the cross S × Red for the fruit weight and number of branches. Narrow sense heritability indicated low additive gene action governing watermelon fruit weight and number of side branches per plant. In conclusion, the hybrid S × Red was proposed for the hybrid production of watermelon. However, crossing among various genotypes to produce new recombinant lines is necessary for the hybrid breeding program of watermelons in Iran. | ||
