【Abstract】 "Xiangnong Xiaohuasheng",a spanish type small peanut cultivar,was bred by sexual hybridization (Xianghuasheng 1×Xiangtan Xiaozi) by Hunan Agricultural University. It has outstanding characteristics: 1) On the basis of keeping nice traditional taste quality of local small-seed cultivar,it amounted 3717.6 kg/hm2 pod yield,stably and significantly higher than control cultivar Qiyang Xiaozi by 12.5% in Hunan provincial peanut cultivar regional trial. 2) The oleic acid to linoleic acid ratio (O/L) amounts to 1.36,higher than the exporting peanut breeding target (1.30) made by national science and technology planning project,means long shelf life. It has good commercial quality as well. 3) Early maturation,strong seed dormancy,strong synthetical resistance,i.e. high acid soil resistance,bear to barren land,high resistance to leaf spot disease,middle resistance to rust disease,Leptosphaerulira crussiasa (Sechet) Jackson & Bell,light Corticium rolfsii Saccardo and Rhizoctonia spp infection. It was registered and released by Crops Variety Approval Committee of Hunan Province in April 2009.更多还原
