7个高油酸花生新品种的丰产性和脂肪酸成分评价

摘要

To promote the industrialization of high -oleic (HO)peanuts,7 newly -bred HO peanut va-rieties were evaluated at different locations.The results showed that,when cultivated in Laixi,Shandong Prov-ince as spring peanuts,the kernel yields of new cultivars were comparable to or even higher than those of nor-mal -oleic and high -yielding controls,such as Huayu 20 or Huayu 25,Huayu 33.When planted as summer peanuts in Anhui Province,the kernel yields of these new HO cultivars were superior to HO checks,Huayu 32 or Huayu 951.Among which,Huayu 664,Huayu 666,Huayu 963 and Huayu 964 performed very well.The oleic acid content of 7 HO cultivars were all over 80%,and the ratio of oleate to linoleate (O /L)was more than 23,in which,Huayu 964 had the highest O /L of 34.04.%为推进高油酸花生产业化，对山东省花生研究所最新育成的7个高油酸花生品种进行了多点鉴定。结果表明：山东莱西春播种植，供试新品种的子仁产量水平与当前推广的普通油酸高产品种花育20号或花育25号、花育33号相当或更高；在安徽夏播种植其子仁产量高于高油酸对照品种花育32号或花育951，尤以花育664、花育666、花育963和花育964的产量优势更为明显；7个品种油酸含量均在80％以上，油亚比均高于23，其中花育964油亚比最高，达34．04。
