摘　　要：全151S是以柱头外露率高和抗倒性强的1892S与分蘖力强、米质优的新安S杂交后再与1892S回交育成的新的水稻光温敏核不育系。该不育系具有株高矮、茎秆粗壮、配组优势强、异交结实率高等优点,2017年通过安徽省技术鉴定。利用全151S组配育成的杂交组合Q两优851和Q两优丝苗已经通过长江中下游中籼品种审定,审定编号分别为国审稻20196111和国审稻20196109。Quan 151S, developed by crossing 1892S(high stigma exsertion rate and strong lodging resistance) with Xin’an S(strong tillering ability and good grain quality) and backcrossing to 1892S, is a new photoperiod-and thermo-sensitive genic male sterile(PTGMS) line in rice. With the advantages of short plant, thick and sturdy culm, strong heterosis and high outcrossing rate, etc., it was technically identified in Anhui Province in 2017. The hybrid combinations Qliangyou 851 and Qliangyou Simiao derived from Quan 151S have been registered and released as a medium indica rice for the middle and lower reaches of Yangtze River with the registration numbers of Guoshendao 20196111 and Guoshendao 20196109, respectively.
