| Abstract: | In this text,the cold-resistance of cold-resistant rice variety-Yuhui 72 and its filial generation were identified contrasted with Zhuqing,Earlier indica rice14 and other varieties with the cold resistance.In 2003,the conductance rates of dry before freezing and after freezing were measured,the investigation of the influence on the root and stem was carried out with the freeze injury.The result indicated that new variety,Zhi 254 and 1401,was with extremely good cold resistance and with fine agricultural property. |
