Item Estimation of inbreeding depression through embryo and kernel analysis in coconut types(Kerala Agricultural University, 1994) Manju, P; Gopimony, RThe study was undertaken to assess the breeding value of the three Komadan generations, the WCT and the NCD by selfing them and studying the extent of inbreeding depression. The three Komadan generations behaved as a distinct group against WCT and NCD types for weight of embryo and kernel. The significant reduction in embryo and kernel weight in the selfed nuts of NCD and WCT indicated a high degree of inbreeding depression. The results indicate the high degree of homozygosity achieved by the Komadan types through natural self pollination as against heterozygosity in WCT and NCD.Item Seedling progeny analysis in coconut types(Kerala Agricultural University, 1995) Manju, P; Gopimony, R; Nampoothiri, K U K; Saraswathy, PThe study was undertaken to identity prepotent palms from among five coconut types vi/.., three Komadan generations. West Coast Tall and Natural Cross Dwarf based on growth rate of seedlings at the 9th month of germination. For most of the seedling characters, Komadan generations (Manju, 1992) showed significant superiority over WCT and they behaved as a distinct group with regard to total leaf area over both WCT and NCD. They were also found to be significantly superior to WCT for seedling vigour index and number of seedlings with split leaves. The three Komadan generations were on par regarding recovery ot quality seedlings and were significantly superior to WCT. Based on this character, 20 per cent of the palms in Komadan were identified to be prepotent.
