摘　　要：新品种‘华南16号’(‘SC16’)(Manihot esculenta Crantz cv.SC No.16)是以木薯品种‘华南8号’(‘SC8’)为母本和引进品种‘Q10’(I93/0665)为父本进行人工杂交获得F1杂交种子,经实生苗试验、初级品比、高级品比、区域试验和生产性试验等选育而成。其鲜薯产量在区域试验和生产性试验分别为50.15 t/hm2和45.82 t/hm2,比我国主栽品种‘华南205’(‘SC205’)分别增产55.45%和35.85%;块根淀粉率分别为25.42%和26.10%,略低于‘SC205’(对照);鲜薯氰苷含量为29.70μg/g,属于甜木薯品种。综合试验结果表明,‘华南16号’是1个株型优良、高产,且能够密植与机械化采收的工业用、食用兼饲用的新品种,适宜在我国广西、广东沿海、海南,以及东南亚地区推广种植。Cassava,an important crop for industrial material in China,has potential for food and feeding.‘South China No.16’(‘SC16’)is a new approved variety,which originating from F1 by crossing between female parent‘SC8’and male parent‘Q10’(I93/0665),and tested by seedling test,primary and advanced line performance test,regional line test and productive test.The average fresh root yields of‘SC16’in the regional trials and productive trials was 50.15 t/hm2 and 45.82 t/hm2,55.45%and 35.85%more over‘SC205’,the main cultivated variety in China,respectively.The root starch content of‘SC16’was 25.42%and 26.10%,which was slightly less than that of‘SC205’.The average cyanogenic glycosides content was 29.70μg/g in its fresh root,meaning that‘SC16’is a sweet cassava variety.Taken together,‘SC16’is a new variety with excellent plant type,high fresh root yield,lodging resistance,concentrated tuberization and better for high dense planting and mechanized harvesting,and could be used for starch industry,food processing and feeding.‘SC16’is suitable for planting in the coastland of Guangxi and Guangdong province,Hainan and Southeast Asia.
