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。
The suitability test of cassava seed introduction was carried out in Hekou County, Yunnan Province, and its main agronomic economic traits were determined. The results showed that the harvest index of cassava varieties was SC10 = 0.77> South China SC9 = 0.69> South China SC7 = 0.68> South China SC5 = 0.61> South China 205 (CK) = South China 6068 = 0.59> South China SC8 = 0.54> South China SC6 = 0.53 . The average yield per plant of the tested varieties was 10.7-35.2 kg. The highest yield of single plant in South China SC10, South China SC7 and South China 6068 was 71, 48 and 47 kg, respectively, indicating that these cassava breeds have larger yield potential. The starch content of the tested varieties was as follows: SC10 = 28.9g / 100g> South China 205 (CK) = 23.7g / 100g> South China 6068 = 22.9g / 100g> South China SC6 = 21.7g / 100g> South China SC8 = 20.8g / 100 g> South China SC7 = 20.7 g / 100 g> South China SC9 = 18.2 g / 100 g> South China SC5 = 16.6 g / 100 g. The results of this research have a certain promotion effect on the development of local cassava industry.
