Abstract
A random sample of 99 dura x pisifera (D x P) biparental progenies from six agencies were evaluated for their yield performance. The performances of the materials from the six agencies were significantly different. On the average the trial produced a fresh fruit bunch (FFB) yield of 123.57 kg/palm/year. Among the six agencies the highest mean yield was 132.01 kg/palm/year from Agency 4. Fifteen outstanding progenies had FFB productions ranging from 138.39 to 158.17 kg/palm/year: these high yields were a result of balanced bunch number (BNO) and average bunch weight (ABWT). A large proportion of the variation - between 80 to 90 percent - was confined to variation at the seedling level. The proportion of genetic variability attributed to progeny differences was 7-20 per cent. Broad sense heritabilities (h2B) using intra-class correlation were 0.39 for ABWT 0.19 for BNO and 0.13 for FFB
