木薯无性系E—24是华南205自然杂交种的无性系后代,经过1983—1986年在广东、广西的多点适应性试验,初步结果表明,在瘦瘠至中等肥力条件下栽培,其块根产量为800～2600公斤/亩,比当前的当家品种华南205和东莞红尾分别增产26.7％和12.8％,有显著的增产效果。其块根干物质含量为32～44.5％,淀粉含量26.7～29.2％,与华南205和东莞红尾的无明显差异;氰酸含量为3.57毫克/100克,显著低于华南205和东莞红尾的。在持续三天10℃以下并有轻霜的天气情况下,冻害极轻,能继继生长,是个高产,低毒,耐寒的优良品系。
The cassava clones E-24 is a clonal descendant of 205 natural hybrids in South China. After the adaptability test in Guangdong and Guangxi from 1983 to 1986, the preliminary results showed that under the conditions of lean to moderate fertility, the root yield 800 ~ 2600 kg / mu, which is 26.7% and 12.8% more than the current varieties of South China 205 and Dongguan Hongwei, respectively, which have significant yield increase effect. The dry matter content of tuberous roots was 32-44.5% and starch content was 26.7-29.2%, which was not significantly different from that of South China 205 and Dongguan red tail. The content of cyanic acid was 3.57 mg / 100 g, significantly lower than that of South China 205 and Dongguan red tail . Under the condition that the temperature is below 10 ℃ for three days and there is light frost, the frost damage is extremely light and can continue to grow. It is a fine line with high yield, low toxicity and cold resistance.
