Item Evaluation of tendernut water in coconut cultivars(2007-02) Dhamodaran, S.; Ratnambal, M.J.; Chempakam, B.; Pillai, R.V.; Viraktamath, B.C.The tendernut water of 12 coconut cultivars was evaluated biochemically to find out a suitable tendernut cultivar. Biochemical evaluation indicated that Chowghat Orange Dwarf (COD) had the maximum amount of total sugars (7.0 g/100 ml) and reducing sugars (4.7g/100 ml) and low sodium and potassium content (20 and 2003 ppm respectively). Scores and weightage were given for tendernut characters following Andersons method and a maximum index score of 73 was given to COD. Four cultivars selected based on biochemical evaluation were subjected to organoleptic test by seven tasters following a non-parametric statistical method. This study also confirmed the superior tendernut quality of COD.Item Heterosis breeding in coconut - Past, present and future(2007-02) Dhamodaran, S.; Viraktamath, B.C.; Iyer, R.D.The coconut improvement programme through breeding was initiated in the early part of the current century. The discovery of hybrid vigour in coconut in India by Patel (1937) was a significant landmark in the history of coconut improvement. Subsequently, systematic efforts were made in Sri Lanka, Ivory Coast and Jamaica which led to the successful exploitation of hybrid vigour in coconut. Selection of elite parental palms, testing their combining ability and establishing seed gardens with promising parental lines for hybrid seed production, are the important steps in heterosis breeding. The desired traits both from Dwarf and Tall parents are brought together in hybrids. Due to the concerted efforts of coconut breeders many hybrids have been relesedfor cultivation in different coconut growing countries. Notable among them is the Ivory Coast hybridMAWA ofl.R.H.O., whichhas been widely distributed in different S.E. Asian countries like Indonesia, Thailand, Malaysia, Philippines etc. The historical background of heterosis breeding, present status and future programmes envisaged in various coconut growing countries have been reviewed in this paper.Item Heterosis breeding in coconut - Past, present and future(1992-05) Dhamodaran, S.; Viraktamath, B.C.; Iyer, R.D.The coconut improvement programme through breeding was initiated in the early part of the current century.

Selection of elite parental palms, testing their combining ability and establishing seed gardens with promising parental lines for hybrid seed production, are the important steps in heterosis breeding. The desired traits both from Dwarf and Tall pareuts are brought together in hybrids. Due to the concerted efforts of coconut breeders many hybrids have been released for cultivation in different coconut grOWing countries. Notable among them is the Ivory Coast hybrid MAWA of I.R.H.O., which has been widely distributed in different S. E. Asian countries like Indonesia, Thailand, Malaysia, Philippines etc. The historical background of heterosis breeding, present status and future programmes envisaged in various coconut growing countries have been reviewed in this paper.Item International Directory of Coconut Workers(2007-02) Rajagopal, V.; Vidyasagar, P.S.P.V.; Viraktamath, B.C.; Solomon, J.J.Item On Visit to the Philippines IBPGR Training Course on Collection, Conservation and Characterization of Coconut Genetic Resources.(1990) Viraktamath, B.C.; Dhamodaran, S.Item Yield of Mangala Arecanut in Goa(1993-09) Mathew, P.A.; Dhandar, D.G.; Viraktamath, B.C.
