摘　　要：以本地当家品种SC205为对照,对17个木薯新品系进行高级系比试验,结果显示,B16的产量极显著高于对照,鲜薯产量达51.83t/hm2,增幅达73.52%;B103、B86、B171、B165、B16、B81和B74品系的干物质含量和淀粉含量显著高于对照,而B107品系的干物质含量和淀粉含量极显著高于对照;另外,B16、B74、B1、B161、B83、B160和B103等7个品系表现出较强的抗逆性。综合各品系的农艺性状,表明B16是值得进一步进行生产性试验的木薯新品系。The advanced trial for 17 new cassava breeding lines was carried out, and local dominant variety SC205 was used as the CK. The results showed that the yield of breeding line B16 was significantly higher than that of SC205, and the fresh tuber yield was 51.83 t/hm^2 and increased by 73.52%. The dry matter and starch content of B103、B86、B171、B165、B16、B81 and B74 were significantly higher than those of SC205, and those of B107 was significantly higher than those of the control. Moreover, seven breeding lines including 1316、B74、B1、B161、B83、B160 and B103 had stronger resistance to stress. Therefore, according to the agronomic traits of these lines, B16 is a new one worth to be tested in further productive trial.
