摘要
在云南省河口县开展木薯良种引种适宜性试验研究,并对其主要农艺经济性状进行测定。结果表明,木薯品种的收获指数依次为华南SC10=0.77>华南SC9=0.69>华南SC7=0.68>华南SC5=0.61>华南205(CK)=华南6068=0.59>华南SC8=0.54>华南SC6=0.53。参试品种的平均单株产量为10.7~35.2 kg,其中华南SC10、华南SC7及华南6068的单株最高产量分别为71、48和47 kg,表明这些木薯良种具有较大的增产潜能。参试品种淀粉含量依次为华南SC10=28.9g/100g>华南205(CK)=23.7g/100 g>华南6068=22.9 g/100 g>华南SC6=21.7 g/100 g>华南SC8=20.8 g/100 g>华南SC7=20.7 g/100 g>华南SC9=18.2 g/100 g>华南SC5=16.6g/100 g。此研究成果对当地木薯产业的发展具有一定的促进作用。
Cassavas were introduced and suitability studied in Hekou County of Yunnan Province. Cassava's main characters were determined. The results show that harvest index of the eight cassava varieties respectively is SC10:0.77 〉SC9:0.69 〉SC7:0.68 〉SC5:0.61 〉205 :SC6068:0.59 〉 SC8:0.54〉SC6:0.53, and yield per plant is between 10.7and 35.2 kg. Yield per plant of SC10, SC7 and SC6068 is the highest as follow: 71kg, 48 kg and 47 kg. These results show that these cassavas have a lot space about yield. Starch content of the eight cassava varieties respectively is SC10=28.9 g/100 g 〉 C205:23.7 g/100 g〉SC6068=22.9 g/100 g〉SC6=21.7 g/100 g〉SC8:20.8 g/100 g〉SC7:20.7 g /100 g〉SC9=18.2 g/100 g〉SC5=16.6 g/100 g. These research results may stimulate development of Hekou county cassavas industry .
