| 摘 要： | 通过对木薯种质的寒害调查,表明木薯抗寒力因品种不同而异,抗寒能力较强的品种（系）有罗勇5号、华南6号、华南8号、CMR36-34-1等;其次是华南5号、GR891、GR1-1,SM1741、华南102;最弱的是野生木薯、桂热3号、桂热引1号、KM937-1、巴西900等,摸清了木薯种质间抗寒力的差异,从中筛选出抗寒品种（品系）,为木薯的北移种植研究和减少木薯寒害损失提供科学的依据。调查结果还表明,同一品种中未收获种茎比已收获的种茎抗寒强。

| Abstract: | This study investigates cold damage to Cassava cultivars and suggests that the cold hardiness of Cassava varies in different cultivars. The result indicates the cultivars with strongest freezing resistance ability are Luoyong 5,Huanan 6,Huanan 8,CMR36-34-1,and the stronger ones are Huanan 5,GR891,GR1-1,SM1741,Huanan 102,and the weaker ones are native cultivars：Guire 3,Guire 1,KM937-1 and Brazil 900. Knowing the differences of cold hardiness among different Cassava germ plasms so as to select cold resistant varieties can provide scientific evidence for planting in the North and decreasing cold damage The result also suggests the unharvested stem is stronger than the harvested one in cold resistance. |
