PARENT OFFSPRING RELATIONS OF NUTRITIONAL QUALITY TRAITS IN 8 X 8PARTIAL DIALLEL CROSS OF FRESH TOMATOES

Combining abilities for nutritional quality content were examined in tomato to understand the inheritance pattern of total soluble solids, titrable acidity, carbohydrates, proteins, carotenoids, ascorbic acid, potassium, lycopene and fruit yield plant -1 . This experiment comprising a total of 64 treatments (28 F1+28 F2+ 8 parents) was evaluated in RBD. The results indicated that most of the traits were governed by additive gene action however non additive gene actionwas also important. The parent Pusa Ruby was found to be good general combiners for yield and nutritional traits and hence could be utilized in multiple breeding programs in future. The cross Pusa Ruby x Arka Vikas was desirable for fruit yield as well as nutritional characters since it inherited all nutritional traits except TSS content in F1generation and carotene content in F2 generation in desired direction.
