摘要:

为选育高产稳产、高淀粉、抗朱砂叶螨且适应性广的木薯新品种,以株型紧凑、高产木薯品种‘华南11号’(‘SC11’)为母本,以高淀粉、抗朱砂叶螨木薯品种‘桂热891’(‘GR891’)为父本,通过系统选育程序,育成优良木薯新品种‘云热薯1号’。在区域试验和生产试验中,其鲜薯产量分别达42.42 t/hm2和40.44 t/hm2,比中国主栽品种‘华南205’(‘SC205’)分别增产14.09%和16.41%;鲜薯淀粉含量分别为26.11%(比重法)和36.02%(酸水解法),均高于对照‘SC205’;平均螨害指数分别为23.72%和26.01%,表现为抗螨。2023年12月25日‘云热薯1号’通过全国热带作物品种审定委员会审定,审定编号为热品审2023004。‘云热薯1号’是一个高产稳产、高淀粉、抗朱砂叶螨的木薯新品种,在云南、海南、江西、广西等主要木薯宜种植区具有较强的市场竞争力,对促进木薯产业增产、增收、增效具有重要意义。

Abstract:

This study aimed to develop a new cassava cultivar with high and stable yield, high starch content, resistance to carmine spider mites, and wide adaptability. Using the compact and high-yielding cassava cultivar 'South China 11' ('SC11') as the female parent and the high-starch, carmine spider mite-resistant cultivar 'Guire 891' ('GR891') as the male parent, a systematic breeding procedure was implemented to develop the new elite cassava cultivar 'Yunreshu No.1'. In regional and production trials, its fresh root yields reached 42.42 t/ha and 40.44 t/ha, representing yield increases of 14.09% and 16.41%, respectively, compared with the main Chinese cultivar 'South China 205' ('SC205'). The starch content of fresh roots was 26.11% (specific gravity method) and 36.02% (acid hydrolysis method), both higher than the control 'SC205'. The average mite damage indices were 23.72% and 26.01%, respectively, demonstrating mite resistance. This variety was officially certified by the National Tropical Crops Variety Approval Committee on December 25, 2023 (Approval No.: Repinshen 2023004). 'Yunreshu No.1' is a new cassava cultivar characterized by high and stable yield, high starch content, and resistance to carmine spider mites. It exhibits strong market competitiveness in major cassava-growing regions such as Yunnan, Hainan, Jiangxi, and Guangxi, and holds significant potential for enhancing cassava production, farmer income, and industrial efficiency.
