Breeding and Utilization of Early Indica Hybrid Rice Weiyou D133

Weiyou D133,developed by the Rice Research Institute of Anhui Academy of Agricultural Sciences, is a new early indica hybrid rice combination for double-cropping system with its restorer line D133 selected and tested from Wenhui 10-35. As early rice,its growth duration is about 110 days,similar to that of Erjiufeng. The experimental results obtained from 4 trials in 3 years showed that it yielded 6.57 t/ha on average,and it was resistant to rice blast,rice whitebacked planthopper and brown planthopper,intermediate- ly resistant to rice bacterial leaf blight. In Sept. 1992,Weiyou D133 was approved by the Committee of Crop Variety Appraisal of Anhui Province and named as "Wandao 35".
