Abstract:

Oil palm (Elaeis guineensis Jacq.) is a perennial monocotyledonous tree belonging to the family Palmae, with a diploid chromosome number, 2n=32. Oil palm (Elaeis guineensis Jacq) is an important edible vegetable oil crop which produces 4-6 tonnes of crude palm oil/ha. As oil palm crop is introduced in India from Africa, it is growing in India under different climatic conditions like high temperature, low humidity and less rainy days. There is a need to develop and strengthen the oil palm breeding program in India as there is a demand from the farmers to cultivate good yielding oil palm hybrids. In Parental analysis study, a total of 400 SSR markers of Elaeis guineensis were used to screen two parental genotypes. Out of 400 SSR markers analyzed for polymorphism, 19 SSR markers (4.75%) were polymorphic and these 19 polymorphic SSRs were used to genotype the 70 F1 progenies of the 240D x 281D cross. So these identified markers were used for further studies such as linkage map construction and mapping QTL’s for yield related traits by using simple interval mapping and composite interval mapping approaches.
