以新引进的8个油棕品种(R1-R8)为材料,从农艺性状方面对其进行了评价.结果表明:从产量性状来看,平均每株每年产棕油量最多的是R7品种(14.75kg),最少的是R4品种(3.58 kg)；从品质性状来看,碘值最高的是R3品种(67.85),最低的是R5品种(59.23).供试品种不饱和脂肪酸(油酸+亚油酸)含量变幅为55.51％～60.54％,食用品质较好.从农艺性状指标的综合评价结果来看,R7品种具有比较理想的株形,生长缓慢、冠幅偏小,而叶片数和果穗数较多,单株产油量最高.%The eight oil palm varieties (Rl-R8) introduced in recent years were evaluated for the morphological-agronomic characters. The analysis of yield characters showed that R7 and R4 accounted for the most and least palm oil production (14. 75 and 3. 58 kg/year), respectively; the variety R3 had the highest iodine value 67. 85 and R5 had the least 59. 23,according to the detection of their quality characters. Addionally,the content of unsaturated fatty acid(oleic acid+oleic acid) in all eight varieties ranged from 55. 51% to 60. 54%, indicating a good edible quality. Judged from the comprehensive evaluation in the agronomic traits, variety R7 possessed a good plant type, including slow growth, lower crown extent, more leaves and bunches, and above all, higher palm oil yield.
