Using target-parent selection and directive single-plant breeding, new high-yielding and low-temperature resistant japonica variety Bijing 41 was breed by Bijie district agriculture institute of Guizhou to counter ecological conditions and rice cultivation production reality of high-altitude and low-temperature mountain area in northwest Guizhou. It increased yield with 8.34% than the contrast Bijing 37 in japonica cultivars regional trail of Guizhou and increased yield with 11.58% than the contrast Bijing 37 in japonica cultivars production trail of Guizhou. Its whole growing period is about 170d,plant height is 95.0~105.0cm, effective panicles is about 292.5 myriad/hm2, mean grains per panicle is 110~140, seed setting rate is above 85% and 1000-grain weight is 26~28g. Rice quality measure analysis showed that Bijing 41 is a low amylose soft rice variety. It was examined and approved by the crops variety examine and approve committee on July in 2003.
