花生新品种粤油5号的选育研究

Development of a New Peanut Variety,Yueyou 5, with High Yield, Early Maturity and Tolerant to Cold

早熟、耐寒、高产、抗锈病花生新品种粤油5号是以"粤油116"作为高产亲本材料,以国际半干旱作物所的早熟品种"ICGV8641"为早熟亲本,以美国引进种质"PI381622"为耐寒亲本,通过有性复合杂交,多世代轮回交替选择、定向选择和多点鉴定等方法培育而成。该品种1998年通过广东省品种审定,1999年被列为广东省重大科技成果推广项目并获全国农牧渔业丰收三等奖,2000～2001年连续两年被国家科技部列为国家重大科技成果推广项目,2002年获广东省科技进步三等奖。

Yueyou 5, a highyielding peanut variety with early maturity and tolerance to cold was derived from a multicross of F1 ×(Guiyou 28×ICG 8641) F1. It gave an average seed yield of 2.9 t ha1 and outyielded the control variety by 9.85% in Guangdong Provincial New Peanut Varieties Trial during 1996～1997. Yueyou 5 matures 6～7 days earlier than the local varieties and tolerance to cold stress during germination in spring season. It was released by Crops Varieties Approval Committee in Guangdong and rewarded by the Guangdong Provincial Government in 2002.
