Abstract：Yuanza 9847 is a peanut variety derived from cross between a cultivar Yuhua 15 as female parent and an interspecific F1 hybrid(Yuhua 7 ×Arachis sp.30136)as male parent by Industrial Crops Research Institute of Henan Academy of Agricultural Sciences.It is characterized with high yield,high oil content and high resistance to multiple diseases.The average pod and kernel yields were 4 180.88 kg/ha and 2 878·58 kg/ha in the summer peanut regional test of Henan province in 2007 - 2008.The yields were 4 715·70 kg/ha and 3 454·50 kg/ha in the summer peanut production test of Henan province in 2009,and were 4 736·70 kg/ha and 3 366·75 kg/ha in the national northern district big peanut regional test in 2008 - 2009.And the same indices were 4 373·25 kg/ha and 3 226·65 kg/ha in the national northern district big peanut production test in 2010.Yuanza 9847 had crude fat content of 55·79%,was highly resistant to net blotch,and resistant to leaf spot,rust,virus diseases and root rot.This variety was released by Henan Variety Evaluation Committee in 2010 and was identified by National Agricultural Technology Extension and Service Center in 2011.It was suitable for planting in Henan, Shandong,Jiangsu,Anhui,Hebei,Hubei and other big peanut production areas.The successful development of the variety revealed the great potentials of elite wild Arachis species in the genetic enhancement of the cultivated peanut and shed some enlightenments in the handling of interspecific hybrids.
