    Studies on intervarietal hybrids of tomato
    (Division of Agricultural Botany, College of Agriculture, Vellayani, 1975) Rema Bai, N; Mary K George
    The present investigations were carried out in College of Agriculture, Vellayani during the year 1974-75. Five varieties of Lycopersion esculentum viz., YRFN-3, Mech9, VF36, Walter and Local were utilised for intercrossing. Investigations on the quantitative and qualitative characters, heterosis, hybrid sterility and sucrose content of the parents and hybrids were undertaken. Though the hybridisation work was done in all combinations, there was fruit setting only in fourteen crosses. YRFN-3 as male parent failed to cross with any other varieties except with Walter. In this case though fruit setting was occurred, seeds obtained were not viable. YRFN-3 as female parent also failed to cross with any other varieties except with Local.
