ThesisItem Open Access Identification of prepotent motherpalms in coconut (Cocos nucifera L.) variety, KOMADAN(Department of Plant Breeding, College of Agriculture, Vellayani, 1982) Shylaraj, K S; KAU; Gopakumar, KA systematically arranged experiment on Pedigree Progeny Analysis was conducted during 1981-82 in the premises of the College of Agriculture, Vellayani, with 40 randomnly chosen trees of the coconutpalm, type KOMADAN. The advantages of following a Triphasic Selection Schedule carried out at the levels of the motherpalm population, seednuts and the one year old seedling progeny in the nursery, and the special worth of identifying, on the basis of the information made available through the conduct of the early seedling progeny analysis, the prepotent palms, are substantiated. Accordingly, a recommendation in favour of confining for benefit, extensive seednut collection, exclusively to such palms as mentioned above, identified from among those in a chosen lot, characterized by phenotypically distinguishable overall healthy outlook, followed by exposure to a procedure of more intensively rigorousselection in the nursery, of superior seedlings is proposed.ArticleItem Open Access Seed germination in lemongrass and palmarosa(Kerala Agricultural University, 1988) Kuriakose, K P; Shylaraj, K S; KAUArticleItem Open Access Suitability of Vyttila-4 as a rice variety for coastal saline areas(Kerala Agricultural University, 1998) Shylaraj, K S; George, T U; George, K M; Sasidharan, N K; KAUA breeding programme was undertaken at the Rice Research Station, Vyttila to evolve high yielding saline tolerant rice variety suitable for pokkali ecosystem. A cross was made between Chettivirippu and IR 4630-22-2-17 and effective selection was made for the high yielding saline tolerant genotypes suited to coastal saline soils. The selected genotype K AU 906 performed best in comparative yield trials, farm trials and national level screening trials. The high yield of the genotype is mainly due to higher number of productive tillers and filled grains per panicle, low sterility percentage and higher 1000 grain weight. The genotype was also found to be having maximum stability of performance over years and was released as Vyttila 4 for cultivation in coastal saline soils.ArticleItem Open Access Testing for prepotency in coconut palm(Kerala Agricultural University, 1987) Shylaraj, K S; Gopakumar, K; KAU
