Item Mother palm and seedling selection in coconut(Kerala Agricultural University, 1979) Kannan, K; Narayanan Nambiar, P KStudies were undertaken at the Coconut Research Station, Pilicode to find out influence of mother palm and seedling selection on the performance of the progenies. Palms yielding more than 80 nuts per annum and palms selected at random (bulk mother palms) are found to produce high yielding progenies. Palms giving an yield of less than 20 nuts are defenitely unsuitable for seednut selection. Seedling selection though necessary need not be as stringent as is advocated at present since the yield difference between vigorous and intermediate seedlings is not significant. However, for ensuring better establishment, early flowering and higher yield, poor seedlings should be rejected.Item Studies on the open pollinated progenies of tall X dwarf coconut hybrids(Kerala Agricultural University, 1976) Kannan, KA study of the performance of the open pollinated progenies of T x D palms was conducted at the Coconut Research Station, Pilicode. Considerable reduction in the expression of hybrid vigour was observed from the iiisi generation T x D to the second generation open pollinated progenies. In respect of age at first flowering growth rate and leaf production they were more equal to the West Coast Tall than to T x D. About half the population gave higher yield of nut and copra than the parents while the other half was low yielders. A few of the parent palms produced high percentage of high yielders which may be due to prepotency.
