    Genotype - environment interaction and stability analysis for bunch yield and its components, vegetative growth and bunch characters in the oil palm ( Elaeis guineensis Jacq )
    (2007) Ong, E.G.; Lee, C.H.; Law, I.H.; Ling, A.M.
    The development of oil palm planting material ('Dura' x 'Pisifera') with a high level of performance over a wide range of environments is an important objective for most breeding programs. In Malaysia, four companies cooperated and evaluated seven Nifor hybrids (Nigerian institute for Oil Palm Research) and four Malaysian hybrids for five years at four locations in Malaysia. There were significant differences among the hybrids for all the bunch yield and its components (bunch number and bunch weight), some vegetative growth and bunch characters analyzed. Significant G x E interactions were observed for the bunch yield and its components, some vegetative growth characters (height, petiole cross section and leaf area) and some of the bunch characters (kernel to fruit, wet mesocarp to fruit and oil,' * .ich). The significance of these GxE interactions was discussed. In the regression analysis for the yield and the vegetative growth characters, the growth response and stability indices of these traits were so examined.
