Item Breeding behaviour of certain hybrids and their parents of arecanut (Areca catechu L.)(Journal of Plantation Crops, 2006) Ananda, K.S.; Rajesh, B.Item Secondary selection in Mangala (VTL 3) cultivar of arecanut (Areca catechu L.)(2004) Ananda, K.S.; Rajesh, B.; Chowdhary, B.S.An attempt has been made to bring out the varietal purity and improved yield performance if any, through inter se /sib-mating of the typical palms of the arecanut variety Mangala, and secondary selection was exercised for desirable morphological, reproductive and yield components among the inter se mated progenies. A set of 13 inter se combinations were produced by selecting typical Mangala mother palms growing at CPCRI Regional Station. Vittal and planted in a randomized block design replicated six times with 9 palms per replication during 1986-87, with a view to undertaking secondary selection at CPCRI, seed Farm, Kidu. Recording of morphological growth parameters and also recovery of typical palms based on morphological and visual observations were done during 1991. Observations on yield components such as number of nuts produced per palm and chali yield/palm have been recorded for seven consecutive years from 1991-1997. Fruit component traits such as fruit length (cm), fresh fruit breadth (cm), fresh fruit weight (g), husk thickness (cm), dry fruit weight (g), kernel length (cm), kernel breadth (cm), dry kernel weight (g), d q husk weight (g) and recovery (%) were also worked out for the same. Among the progenies of thirteen inter se combinations. cent percent typical Mangala palms were recovered from three combinations namely Palm Nos. 56 x 3M), 157 x 71 and 35 x214 compared to other combinations and open-pollinated progenies. Analysis of data revealed the significant differences among the inter se combinations for characters studied. Among these, 47 x 93.185 x 42.35 x 214 and42 x 3M) inter se combinations showed higher values for production of nuts (378.08 350.27, 342.68 and 321.64 nuts/palm/year), and chali yield (3.59. 3.45.3.34 and 2.94 kg per palm/year) with 46.53,40.82, 36.33, 20.00 percent increase in chali yield over open-pollinated progenies. The highest (24.08%) recovery of chali was noticed in 47 x 93 combination followed by combinations 35 x 214 (23.53%). 154 x 7 (22.@%), 56 x 300 (22.48%), 42 x 300 (21.65%) and 150 x 19 (21.608). while the inter se combination 177 x 95 showed the lowest recovery of 17.28% and the open-pollinated Mangala recovered only 21.04% dry kernel from the fresh nut. Overall, the combinations 47 x 93,35 x 214 and 154 x 7 exhibited their superiority for most of the nut characters. In this study, it is observed that the superiority of inter se progenies of different combinations for recovery of typical Mangala palms as well as for their performance in production of nuts, chali yield and fruit components over the progenies obtained after open pollination, and the alternate bearing nature is also minimum in inter se progenies.Item Variation in germination, seedling morphology and bio-chemical traits among indigenous arecanut (Areca catechu L.) accessions(Indian Society for Plantation Crops, 2008) Ananda, K.S.; Rajesh, B.; Shobha, D.Item Variations in Chlorophyll and Polyphenols in Exotic Arecanut (Areca catechu L.)
