摘  要:新安S是安徽荃银农业高科技研究所以广占63-4S为母本,具隐性浅褐色颖壳的爪哇稻材料M95为父本杂交后经系选育成的籼型水稻光温敏核不育系,其不育起点温度低(在14.5 h日照下不育起点温度≤23.5℃),不育性持续时间长(在合肥长达30 d以上),败育彻底,抗病性较强(对白叶枯病抗性5级,对稻瘟病抗性1级),米质较优,尤其是其种子稃壳具有浅褐色标记性状。新安S配合力强,可繁性好,用其配制的杂交稻新组合新两优6号具有高产和标记防伪等特点,2005年3月通过安徽省品种审定,2006年1月通过江苏省品种审定,2006年被农业部确认为超级稻品种。Xin'an S, derived from the cross of Guangzhan 63 -4S (as the female) and M95, a javanica line with light brown glumes controlled by recessive genes and developed by the Anhui Win-All Hi-teeh Agricultural Research Institute by way of pedigree selection, is a new indica PTGMS line in rice. It was certified technically in Anhui in March, 2005. It had a long stable sterile period ( over 30 days at Hefei, Anhui) with a complete male sterility and a low CSIT ( ≤23.5℃ ) under the daylength of 14.5 hours). It showed a good resistance to blast (Scale 1 ) and bacterial leaf blight ( Scale 5 ) , a good flowering habit with a high outcrossing rate in hybrid seed production and good grain quality. Especially, its glume color is light brown thus it can be used as a morphological marker. Furthermore, its hybrids showed a strong yield heterosis. Among them, Xinliangyou 6 (Xin'an S/Anxuan 6) was registered and released in Anhui in March, 2005 and in Jiangsu in January, 2006, respectively. In 2006, it was approved as a super rice variety by the Ministry of Agriculture, China.
