| dc.description.abstract | Seedlings of eight combinations of Dwarf female x Tall male obtained from crosses between five Dwarf genotypes and three Tall genotypes were studied to identify the parental combination which would yield maximum number of hybrids. The palms were selected on the basis of nut characters like shell and copra content in the husked nuts of dwarf palms and husk and copra content in the fruits of tall palms. The seedlings obtained from these combinations were scored for heterotic hybrids on the basis of petiole colour and vigorous growth of the seedlings in the nursery. The study has indicated that to obtain maximum number of hybrid seedlings, it is preferable to select dwarf palms which yield nuts having a low shell content (less than 20 per cent of husked nut weight) as pistillate parents and tall palms which yield nuts which have less husk content (less than SO per cent of the weight of fruit) and a high copra content per nut (above 150 gm per nut) as pollen parents. It may be possible to identify individual palms in both the parents which when combined may yield a large number of hybrid seedlings. Seedlings of the best combiners should be utilized for laying out hybrid seed gardens for large scale production of hybrids. | en_US |
