Combining ability studies with positional male sterile lines in tomato


Journal of Maharashtra Agricultural Universities 13(3): 261-262
Combining ability studies with positional male sterile lines in tomato
A line x tester analysis involving 16 newly developed 'positional' male-steriles and three pollinators revealed pre-dominance of non-additive gene action for number of branches, number, weight and yield of fruits in tomato. Pusa Ruby revealed high GCA for all characters. The 'positional' male steriles No 5-1 and 16-2 were desirable combiners for fruit yield. The male steriles No 95, 220 and 13-4 were desirable for fruit size. Number 10-3, No 4-3 and 5-1 were good combiners for fruit number. Generally high GCA for fruit yield was associated with high or medium GCA for fruit number.
