Item Characterization of coconut germplasm based on fruit component analysis(2007-02-08) Rao, E.V.V.B.; Vasudevan Pillai, R.The coconut germplasm collection at the Central Plantation Crops Research Institute consists of 62 exotic and 32 indigenous accessions. It is by far the largest collection available anywhere in the world, comprising representative samples from geographically divergent populations. The germplasm collection is divided into four major geographical sets bated on the location of collection, namely, accessions from countries hi South-East Asia, Pacific Islands, North-Central and South-American, and African region. Data on yield and nut characters in 40 accessions are presented in mis paper. The annual out-turn of copra ranged from 7 to 30 kg/palm/year in Tall cidtivars while in the Dwarfs it was less than 10 kg/ palm/year. The classification system based on fruit component analysis, and the time taken for germination, has been adopted to identify the degree of introgression in different accessions. Priority areas for future collections are also discussed.Item Coconut cultivation in Lakshadweep its prospects and problems(2007-02-08) Vasudevan Pillai, R.Item Coconut varieties and hybrids(2007-02-08) Vasudevan Pillai, R.Item A note on the abnormal developments in an oil palms(1959) Gopinathan Nair, R.; Vasudevan Pillai, R.Item A note on the seasonal variation in yield, nut characters and copra content in a few cultivars of coconuts(1960) Vasudevan Pillai, R.; Satyabalan, K.Item Yield performance and nut and copra characters of eight germplasm introductions in coconut(1977-09) Satyabalan, K.; Vasudevan Pillai, R.The mean yield of nuts, yield attributes and nut and copra characters of 8 germplasm introductions in coconut, viz. San Ramon (Philippines) and Borneo* (South-East Asia), •Seychelles (Indian Ocean), Zanzibar and Kenya* (East Africa), British Solomon Islands and Guam (Pacific Islands) and Jamaica (West Indies) planted during 1955-56 was studied and compared with one another and with the local West Coast Tall, all grown under similar conditions. The yield attributes studied were spathe production, female flower production and setting percentage. For nut and copra characters, the weight of fruit, weight of husked nut and weight of components of husked nut (like water, kernel and shell and weight of copra) were studied. The varieties showed a wide range of variation in these characters. There was not much variation in the nut and copra characters of some varieties lite San Ramon, Seychelles and British Solomon Islands when compared with those in their habitats in spite of the different climatic and environmental conditions obtaining here. Zanzibar* and British Solomon Islands, besides the local West Coast Tall were better in the yield of nuts. San Ramon, Zanzibar, Guam and the local West Coast Tall* were better in copra outturn*. These tall varieties have been grouped into 4 forms on the basis of the percentage of husked nut in the fruit, and the percentage of water, kernel, shell and copra in the busked nut.
