湖南地区鲜食木薯品种比较试验初报

Preliminary Comparative Experiment on Fresh Cassava Varieties in Hunan

以木薯品种‘SC205’为对照,对‘SC9’、‘SC6068’、‘南植199’、‘面包木薯’4个鲜食木薯品种进行比较试验。结果表明:4个鲜食品种产量均低于对照,其中‘南植199’、‘SC9’、‘面包木薯’产量与对照相比差异不显著,‘SC6068’产量最低,显著低于对照;‘SC9’干物率和淀粉含量显著高于对照,其余品种之间均无显著性差异;‘SC9’生长势最强,与其他品种差异呈显著水平;综合4个鲜食木薯品种表现,以‘SC9’、‘南植199’和‘面包木薯’适宜在湖南地区种植。

Cassava variety‘SC205’was used as the control in the experiment, four fresh cassava varieties, which were‘SC9’‘,SC6068’, ‘Nam-sik199 ’and‘Bread Cassava,’were selected for comparative experiment. The results showed that：the yield of‘SC205（CK）’ was the highest. The yield of 4 fresh varieties were lower than ‘SC205（CK）’, and the yield of ‘Nam-sik199’ was in the first place. There was no significant difference between the yield of ‘SC9’、‘Bread Cassava’ and ‘SC205’. The yield of ‘SC6068’ was the lowest, which was significantly lower than ‘CS205（CK）’ .The dry matter and starch content of ‘SC9’were significantly higher than the control. There was no significant difference between the other varieties yield; The growth potential of ‘SC 9’ was the most powerful, which was significantly higher than other varieties. According to the comprehensive performance of four fresh cassava varieties, ‘SC9’,‘Nam-sik199’and ‘Bread Cassava’ were suitable for planting in Hunan.
