摘要
花生品种88／BC2-11-1是采用栽野杂交后代“贺粤1号×A．correntinaF5”作母本．高抗青枯病品种“粤油92”作父本进行杂交选育而成的高产、优质栽野杂交种，具有单株结荚多、荚果均匀、果型美观、蛋白质含量高、稳产性好、抗旱性强等优良性状。2000～2002年参加广西花生品种区域试验，3年荚果平均产量3712．50kg／hm^2，比对照种桂花17增产425．70kg／hm^2．增产率为12．95％。2003～2005年在合浦、贺州、桂平进行中间试验与示范推广．3年荚果平均产最3826．80kg／hm^2，比对照种平均增产12．35％．达显著水平，累计示范推广2206．78hm^2。该品种的育成对加速项目区花生品种更新换代，缓解当地花生品种退化、杂乱，品质差的矛盾起到了积极的促进作用。
88/BC2-11-1 is a new hybrid peanut variety with high yield and good quality, which was bred through a crossbreeding between the hybrids of heyueyihao X A. correntiNa F5 as female parent and Yueyou 92 with strong resistance to bacterial wilt as male parent. The variety showed good characteristics with more pods per plant, uniform pod, beautiful appearance, high protein content, yield stability and strong drought resistance, etc. When tested in new peanut varieties regional trial in Guangxi during 2000 2002, the average yield of pods was 3712. 50kg/hm^2 increasing 425.70kg/hm^2 over the control variety Guihual7 with increase rate of 12.95%. When demonstrated in Hepu, Hezhou and Guiping during 2003-2005, the average yield of pods were 3826.80kg/hm^2, in^2creasing significantly by 12.35% over the control. The total demonstrated and extended area of 88/BC2-11-1 was 2206.78hm^2, and it has an active promotion to improve the variety renovation and ease the contradiction of degeneration, disorder and low quality of local peanut variety.
