| Abstract | This research aimed to evaluate crosses based on multiple traits and to observe trait interrelationships in tenera oilpalm. Eleven oil palm progenies were tested at Klong Hoi Khong research station, Songkhla province, Thailand. Numerousagronomic traits, yields, and yield components were recorded. The genotype by trait (GT) biplot, correlation coefficient andpath coefficient were applied in multiple trait data. GT biplot graphically displayed the interrelationships among traits andfacilitated visual comparison of each progenies for selection. Cross 132 and 135 were the best for bunch yield and agronomictraits respectively, whereas c119 was the poorest genotype. The useful agronomic traits correlated with yield and yieldcomponent were frond production and leaflet width, while the leaflet number proved to be an important trait as far as theaverage bunch weight was concerned. These traits would help to make the evaluation in the young oil palm possible. |
