摘　　要：为选育株型好、高产、高淀粉、广适性等综合性状优良的木薯新品种,本研究以华南5号(SC5)为母本,华南205(SC205)为父本,通过系统选育程序,育成优良木薯新品种桂薯1289(Gui 1289)。该品种区域性试验的平均鲜薯产量为49.92 t/hm^(-2),比对照南植199(NZ 199)增产24.21%。生产性试验的平均鲜薯产量为50.76 t/hm^(-2),比对照增产21.26%,鲜薯产量表现突出。区域性试验的平均淀粉含量为30.22 g/100 g,比对照增加5.42 g/100 g。生产性试验的平均淀粉含量为29.96 g/100 g,比对照增加5.57 g/100 g。抗螨性田间鉴定结果为中抗。适宜在广西、广东、海南、江西等省(区)木薯种植区推广。本研究为我国实现木薯良种化生产提供新的种质资源,对促进薯农增收、企业增效具有重要意义。A new cassava variety Gui 1289 with excellent comprehensive traits such as good plant type,high yield,high starch,and wide adaptability was bred by systematic breeding procedures using SC5 as the maternal parent and SC205 as the paternal parent.The average yield of fresh roots for this variety was 49.92 t/hm^(-2) in regional test over the years,which was 24.21%higher than that of the control NZ 199.The average yield of fresh roots was 50.76 t/hm^(-2) in production test,which was 21.26%higher than that of NZ 199.The average starch content in regional test over the years was 30.22 g/100 g,an increase of 5.42 g/100 g compared to NZ 199.The average starch content in production test over the years was 29.96 g/100 g,an increase of 5.57 g/100 g compared to NZ 199.The field test of Tetranychus cinnabarinus showed moderate resistance.It is suitable for popularization in cassava planting areas such as Guangxi,Guangdong,Hainan and Jiangxi,and so on.This study would provide a new germplasm resource for achieving high-quality production of cassava in China,which is of great significance to increase the income of the farmers and increase the efficiency of enterprises.
