L62S是以DS为不育基因供体,与抗早衰、株型好的常规稻品种隆粳62号杂交选育而成的粳型光温敏核不育系,2011年9月通过天津市种子管理站成果鉴定。L62S茎秆韧性强,分蘖力强,成穗率高,偏紧穗型;不育起点温度较低(≤23.0℃),不育期间不育株率100%,套袋自交结实率<0.1%;柱头较大,柱头外露率40%左右,其中双边外露率13%,异交结实率较高;米质优,抗早衰能力强。
L62S is a japonica photo-thermo-sensitive genic male sterile line which is based on DS male sterility gene donor and anti-premature aging and good plant type conventional rice variety Longjing 62. In September 2011, it passed Tianjin seed Management station results identification. The stalk of L62S had strong toughness, strong tillering ability, high spike rate and tight spike type. The starting temperature of infertility was lower (≤23.0 ℃), the rate of sterile plants was 100% %; Stigma larger, stigma exposed rate of about 40%, of which bilateral exposure rate of 13%, outcrossing seed setting rate higher; good quality rice, anti-premature aging ability.
