【摘要】 将黔蔗08-558与全国通用原料蔗试验对照种ROC22进行品种比较试验,结果表明:黔蔗08-558属晚熟、中大茎种,其农艺性状及经济性状优于对照种或与对照种无显著差异,旱坡地和田坝地的新植蔗与宿根蔗单产分别超对照种35.91、29.03、26.88、20.68 t/hm2,新植蔗和宿根蔗的蔗糖含量分别超对照种0.5%、2.4%(绝对值),并且该品系适应性广,耐逆性强,宿根性好,丰产稳产。更多还原

【Abstract】 Comparison test between Qianzhe 08-558 and ROC22, the national universal check variety, was conducted. The results showed that Qianzhe 08-558 is of late maturity and of middle size, and its agronomic traits and economic characters are better than or close to those of ROC22. The yield of new-plant crop and ratoon in dry land and irrigated land were 35.91, 29.03, 26.88, 20.68 t/hm2 higher than that of CK respectively. The sucrose content of new-plant crop and ratoon was 0.5%, 2.4%(abosolute value) higher than that of CK respectively. Qianzhe 08-558 is a clone with wide adaptability, strong resistance, good ratooning ability and high yield.更多还原
