10个木薯品种引种贵州低热河谷地区的适应性

Adaptability of 10 Newly Introduced Cassava Cultivars in Low and Hot River Valley Region in Guizhou

为探索贵州栽培木薯的适宜性,促进贵州木薯产业可持续发展,并为木薯产业发展提供品种和栽培技术储备,于2010年引进10个木薯品种,以地方栽培品种SC201为对照,进行木薯引种适应性栽培研究。结果表明:各引进品种均能正常完成生育期,其产量和淀粉含量均高于对照;出苗率以GR3和SC205最好,产量以SC10号和NZ199最好,干物率以GR891和GR3最好,干品淀粉含量以NZ199和GR3最高,鲜薯淀粉含量以GR891和GR3较高,淀粉产量以GR891和NZ199最高。说明贵州适宜种植木薯。

In order to explore the suitability of cassava in Guizhou, promote Guizhou cassava industry sustainable development, and to provide varieties and cultural technology reserve for cassava industry development. An experiment was carried out on 10 newly introduced cassava cultivars to study their adaptability taking SC201 as the control in 2010. The results showed that all the varieties could normally complete growth stages, yield and starch content of introduced cultivars were higher than CK, rate of emergence of GR3 and SC205 were the highest, yield of SC10 and NZ199 were the highest, dry matter rate of GR891 and GR3 were the highest, dry matter starch content of NZ199 and GR3 were the highest, fresh cassava starch content of GR891 and GR3 were the highest, starch yield of GR891and NZ199 were the highest. All above indicated that Guizhou was suitable for cassava planting.
