Item Advances in coconut research and development(2007-02-08) Nair, M.K.; Khan, H.H.; Gopalasundaram, P.; Bhaskara Rao, E.V.V.Item Breeding Methodology as Applicable to Coconut Improvement(1984) Iyer, R.D.; Satyabalan, K.; Bhaskara Rao, E.V.V.; Sukumaran, C.K.Item Cashew research and development(ISPC, CPCRI, 1984) Bhaskara Rao, E.V.V.; Hameed Khan, H.Item Current status of coconut genetic resources research in India(2007-02-08) Bhaskara Rao, E.V.V.; Pillai, R.V.; Ratnambal, M.J.In India coconut germplasm collection programme dates back to 1924, when some cultivars were introduced mainly from important coconut producing countries in Southeast Asia and Pacific Islands. These introductions formed the nucleus material for the crop improvement research programmes. Subsamples generated by collecting both open-pollinated and selfed seeds were assembled at Kasaragod in the forties which at present can be considered as the main germplasm holding. In the early fifties, systematic introductions of exotic germplasm as well as indigenous collections were undertaken. The present holding of 86 exotic and 40 indigenous accessions planted at Central Plantation Crops Research Institute, Kasaragod and World Coconut Germplasm Centre, Andamans forms probably the largest collection in the world. These collections comprise 102 tails and 24 dwarfs, with two accessions classified as semi-tails and one MAW A hybrid introduced from Ivory Coast. While the introductions were limited to few seednuts in each accession, the exotic collection from South Pacific consisted of 100 seednuts each. A limited number of subsamples of germplasm accessions (distinct types) are also being maintained in Agricultural University Research Centres in different coconut growing states. Efforts were made to characterise the germplasm based on the fruit component analysis. Characterisation of indigenous tall types also enabled identification of distinct indigenous types both in respect of morphological characters and fruit components. Efforts made in evaluation indicated the possibility of identifying the elite types by correlating the initial years yield with the stabilised yield.Item High density planting of cashew (Anacardium occidentale L.)(2010) Yadukumar, N.; Bhaskara Rao, E.V.V.Item High yielding coconut cultivars and hybrids(2007-02) Ratnambal, M.J.; Bhaskara Rao, E.V.V.; Iyer, R.D.Item IND 030-Laccadive Micro Tall (IC0430669; INGR13060), a Coconut (Cocos nucifera) Germplasm with Cluster Bearing Heavy Bunches of Micro Nuts(2014) Niral, V.; Augustine Jerard, B.; Samsudeen, K.; Nair, R.V.; Jacob, P.M.; Devakumar, K.; Ratnambal, M.J.; Kumaran, P.M.; Bhaskara Rao, E.V.V.; Pillai, R.V.; George V.

ThomasItem An Index for Evaluation of Coconut Germplasm in the Nursery(2007-02) Bhaskara Rao, E.V.V.; Jacob MathewCoconut (Cocus nucifera L.) is a monotypic species with pantro-pical natural distribution. There are two distinguishable morphological forms, tails and dwarfs. Evaluation of coconut germplasra is a long drawn process due to its long juvenile phase, and also the time it takes for stabilisation of yield. However, preliminary evaluation can be done at different stages ; nursery evaluation based on seedling characters, at the 12th month, juvenile evaluation based on prebearing growth, characters, and economic evaluation at the stabilised yield period, based on flowering and yield data. The possibility of using this index for planning breeding programmes for varietal improvement is discussed.Item An Index For Evaluation Of Coconut Germplasm In The Nursery(1982) Bhaskara Rao, E.V.V.; Jacob MathewCoconut (Cocus nucifera L.) is a monotypic species with pantro-pical natural distribution.

In addition to the Symposium, the following programmes were also arranged: an exhibition with accent on cashew entitled "CASHEW 79"; release of a 12 min long colour film Cashew, which was specially produced for the and occasion; four special slogan cancellations; release of two books "Cashew" and "Bibliography on Cashew". In addition, seven technical and agricultural journals had also brought out special numbers to mark the occasion. In the Symposium, 75 papers were presented, 49 orally and 26 as poster demonstrations, covering all aspects of cultivation, management, technology, and marketing. The highlight of the Symposium was a special discussion on vegetative prop?gation. In this, the work done so far in the various centres was reviewed and suitable recommendations were made for developing the work further. The other recommendations include: setting up of an international cashew germplasm collection centre; developing methodology for enhancement of root growth through growth regulators, rhizobial cultures, etc., developing meristum culture technique for large scale multiplication of elite trees; standardisation of sampling technique for soil and tissue analysis; identifying natural enemies of Helopeltis; studying the pest complex infesting the inflorescence; introducing small devices for processing cashew; studying the possibility of using CNSL for developing unconventional products like plant protection chemicals, drugs and food additives; and using aluminised paper for packing cashew to reduce the cost of cashew.Item Plantation Crops Genetic Resources Research in India(2007-02) Bhaskara Rao, E.V.V.Item Relative Drought Tolerance And Productivity Of Released Coconut Hybrids(1988) Bhaskara Rao, E.V.V.; Pillai, R.V.; Jacob MathewEightyseven coconut hybrids comprising of 21 different Tall x Dwarf, 10 Dwarf x Tall, 51 Tall x Tall, 4 Dwarf x Dwarf and one three way hybrid were studied. Evaluation at 18th year based on cumulative yield, which is representative of true yield potential, was carried out and three hybrid combinations namely, Chandrasankara (CDO x WCT), Chandralaksha (LO x CDO) and Lakshaganga (LO x GB) were identified as superior hybrid combinations. These hybrid combinations gave 19 to 42% more yield over the commonly cultivated WCT. Among these three hybrids, Chandrasankara (CDO x WCT) was found to give 47% higher copra over WCT. Hybrids Lakshaganga (LO x GB) and Chandralaksha (LO x CDO) performed well under drought situations. The drought tolerance in these hybrids was identified to be the contribution from the female parent Lakshadweep Ordinary. The performance of these three hybrids in relation to other hybrid combinations and drought situations is discussed.Item Response of coconut cultivars to the burrowing nematode, Radopholus similis(1988) Sosamma, V.K.; Koshy, P.K.; Bhaskara Rao, E.V.V.Item Response of coconut cultivars to the burrowing nematode, Radopholus similis(2007-02) Sosamma, V.K.; Koshy, P.K.; Bhaskara Rao, E.V.V.Item A Root (Wilt) Disease Resistant Coconut Hybrid And Strategy For Resistance Breeding(1996) Nair, M.K.; Koshy, P.K.; Jacob, P.M.; Nair, R.V.; Bhaskara Rao, E.V.V.; Nampoothiri, K.U.K.; Iyer, R.D.Item Super Yielders In Coconut(1979) Iyer, R.D.; Govindankutty, M.P.; Bhaskara Rao, E.V.V.Item Super Yielders in Coconut(1979) Iyer, R.D.; Bhaskara Rao, E.V.V.; Govindankutty, M.P.Item Susceptibility of Coconut Cultivars and Hybrids to Radopholus Similis in Field(1980) Sosamma, V.K.; Koshy, P.K.; Bhaskara Rao, E.V.V.Item Susceptibility Of Coconut Cultivars And Hybrids To Radopholus Similis In Field(1980) Sosamma, V.K.; Koshy, P.K.; Bhaskara Rao, E.V.V.
