Evaluation of E. oleifera interspecific hybrids and backcrosses

Mohd Din A., . and Rajanaidu N., . (2006) Evaluation of E. oleifera interspecific hybrids and backcrosses. [Proceedings Paper]

The performance of Elaeis oleifera from Panama Costa Rica Colombia Honduras Brazil and Suriname was evaluated at MPOB Research Station Kluang Johor Malaysia. Fresh fruit bunch yield bunch components vegetative traits fatty acid components iodine value and total carotene were analysed. There were significant differences between the six countries for bunch yield oil to bunch height total economic product and iodine value. Generally oleiferas from Suriname recorded the lowest values for the above traits exceptfor oil to bunch. The yield bunch components and vegetative traits performance ofElaeis oleifera x Elaeis guineensis var. pisifera hybrids OxP created using the North Carolina mating deSign I NCM I were evaluated atfour locations in Peninsular Malaysia viz. Kluang Ulu Paka Teluk Intan and Carey Island. There were significant differences between pisiferas paternal parent for fresh fruit bunch bunch number and average bunch weight at Kluang Ulu Paka and Teluk Intan but not at Carey Island. Despite the lower annual rainfall at Teluk Intan and Carey IslandCoastal soils than Kluang and Ulu Paka inland soil the fresh fruit bunch of progenies in the former soil environments were generally higher. The heritability estimates of the three yield components showed great variation based on type of breeding material and the environment where the materials were tested. Generally yield of the hybrid was comparable to E. guineensis with the oil to bunch height total economic product and iodine value being intermediate between the parents. First generation backcrosses BC I using OxP as maternal parent and pisifera as paternal parent showed segregation for traits ofinterest.

Abstract

The performance of Elaeis oleifera from Panama Costa Rica Colombia Honduras Brazil and Suriname was evaluated at MPOB Research Station Kluang Johor Malaysia. Fresh fruit bunch yield bunch components vegetative traits fatty acid components iodine value and total carotene were analysed. There were significant differences between the six countries for bunch yield oil to bunch height total economic product and iodine value. Generally oleiferas from Suriname recorded the lowest values for the above traits exceptfor oil to bunch. The yield bunch components and vegetative traits performance ofElaeis oleifera x Elaeis guineensis var. pisifera hybrids OxP created using the North Carolina mating deSign I NCM I were evaluated atfour locations in Peninsular Malaysia viz. Kluang Ulu Paka Teluk Intan and Carey Island. There were significant differences between pisiferas paternal parent for fresh fruit bunch bunch number and average bunch weight at Kluang Ulu Paka and Teluk Intan but not at Carey Island. Despite the lower annual rainfall at Teluk Intan and Carey IslandCoastal soils than Kluang and Ulu Paka inland soil the fresh fruit bunch of progenies in the former soil environments were generally higher. The heritability estimates of the three yield components showed great variation based on type of breeding material and the environment where the materials were tested. Generally yield of the hybrid was comparable to E. guineensis with the oil to bunch height total economic product and iodine value being intermediate between the parents. First generation backcrosses BC I using OxP as maternal parent and pisifera as paternal parent showed segregation for traits ofinterest. Oil to bunch iodine value and carotene content ofsome individuals showed improvement and this suggests that transfer of genes for traits of interest has taken place from one species to the other.
