  • The newly bred Fulong S2,a low-temperature sensitive genic male sterile line rice,was developed by crossing Tianfeng S2 with Longyou-2 and by combined selection of blast resistance in blast area,eco-stress for stable sterility and shuttle breeding.Tianfeng S2(used as TGMS gene donor)has characteristics of early mature,good flowering and low-temperature sensitive genic male sterility.Longyou-2 is of high quality,good plant type,late mature,blast resistance and cold tolerance.The new breed was appraised by Fujian Science and Technology Department in 2006.It has good characteristics,such as low critical sterility-inducing temperature(≤ 23.5 ℃),stable sterility,long and stable sterile duration(104d),basic vegetative growth type,moderate growth period,good blast resistance,good combining ability,high stigma exertion and out-crossing rate.These factors suggest that Fulong S2 could be suitable for developing new super hybrid rice of wide adaptability,good quality and high yield with practical applications.
