Heterosis in some bacterial wilt resistant intervarietal crosses of tomato

Thirty hybrids and thirteen parental lines were vevaluated for heterosis for plant height, weight and number of fruits/plant, size of fruit and T.S.S. in a bacterial wilt sick plot. Mean performance of hybrids was superior to that of the inbreeds for most of the traits. Nine hybrids significantly out yielded their better parents. The best ten hybrids for yield were identified. Heterotic hybrids can be developed from the parental lines possessing bacterial wilt resistance.
