摘　　要：新两优6380系南京农业大学水稻研究所用自育恢复系D208与光温敏核不育系03S配组育成的两系杂交中籼稻新组合,2007年1月通过江苏省品种审定。该组合高产稳产,在2004—2006年江苏和国家中籼区试中,产量均居参试组合第1位,比对照极显著增产;耐纹枯病、抗褐飞虱,对稻瘟病和白叶枯病抗性较强,综合抗性突出;米质优良,达国标优质稻谷3级标准;适应性广,适宜在长江中下游稻区中上等肥水条件下作中稻种植。Xinliangyou 6380 （03S/D208） is a new two-line medium indica hybrid rice combination developed by the Rice Research Institute of Nanjing Agricultural University, and it was certified and released to commercial production by the Jiangsu Provincial Crop Variety Appraisal Committee in January, 2007. In the trials from 2004 to 2006, this combination showed high-yielding ability （It yielded very significantly higher than check hybrids and ranked No. 1 in both the national or Jiangsu provincial yield trials and farmers＇ field demonstration during 2004 2006） , multiple resistances （rice blast, bacterial leaf blight, sheath blight and brown planthopper, etc. ） , good grain quality （reaching the 3^rd class of state standards of fine grain quality rice） and wide adaptability （suitable for growing in the provinces of Jiangsu, Anhui, Hubei, Hunan, Jiangxi, Henan and Fujian, etc. ）. The breeding procedure of its restorer line, and the applying technical points of high-yielding cultivation and hybrid seed production of Xinliangyou 6380 were also introduced in this paper.
