    Screening brinjal varieties for wilt resistance
    (Kerala Agricultural University, 1974) Gopimony, R; Mary K George
    Thirty six brinjal varieties including two wild ones were screened against bacterial wilt disease at Agricultural College, Vellayani, during 1975- 1976. Twelve varieties which were found to be disease free in the preliminary trial were subjected to artificial wilt infection under replicated trials and found that only one variety namely S. melongena var. insanum (wild brinjal) was resistant to wilt. Dipping of seedlings in fresh bacterial ooze just before transplanting was found to be equally effective in inducing the disease compared to the more complicated artificial inoculation methods.

    Pollination studies in pineapple varieties
    (Kerala Agricultural University, 1976) Gopimony, R; Balakrishnan, S; Kannan, K; Gopalakrishnan, R
    study was undertaken using four varieties of pineapple to find out the time of anther debiscence and flower opening, time interval between various stages of flower development and best time of hand pollination for maximum seed production, i !u- time of flower opening and anther dehiscence in 'Kew* pineapple was found to be between 4 . 1 5 am and S a m The time interval between various stages of flower development was studied and found to be much shorter than those observed under Hawaii conditions. The results from the pollination trialshave shown that hand pollination in 'K.ew' variety of pineapple using pollen from three other compatible varieties can be successfully done at any time between 4.15 and 10.45 am.

    Comparative study of certain fruit qualities of twenty pineapple varieties
    (Kerala Agricultural University, 1978) Gopimony, R; Balakrishnan, S; Marykutty, K C
    A study was undertaken to evaluate the fruit quality of twenty pineapple varieties during the fruiting season of 1975-76 at the Pineapple Research Centre, Vellanikkara, Trichur. In fruit weight, Kew was found to be far superior to all other varieties except Smooth Cayenne. But in certain other dessert qualities like colour and texture of flesh, flavour, sweetness and T. S. S. varieties like Mauritius, McGregor, Ripley Queen, Queen and Valerabalanga were found to be superior to Kew. The variety Valerabanga was found to show a superior sugar-acid blend as compared to Kew. This suggests its use as a parent material in breeding works for further improvement of Kew.

    Inheritance of fruit colour in normal and irradiated progenies of brinjal
    (Kerala Agricultural University, 1980) Gopimony, R; Mary K George; Gopinathan Nair, V
    The inheritance of fruit colour in brinja! (Solarium metongena) was studied by analysing the progeny belonging to the F, M2, FjM^ and F3M generations resulting from a cross between varieties insanum and purple giant followed by gamma irradiation. The F0 phenotypic frequencies fitted very well with the dihybrid ratio indicating that the fruit colour is governed by two independently inherited genes. Three colour mutants, namely, purple, mottled green and white were induced in the F]MI generation by the irradiation. The appearance of these mutants is explained as due to independent mutations at either or both of the two genetic loci. The colour pattern in the F3M., progenies derived from the F, Mj mutants substantiates the two gene mechanism for the inheritance of fruit colour. The genotypes for the different colour types in the FL, F, and FlMl mutants have been indicated and discussed.
