摘  要：
【目的】研究不同食用木薯品种的生长发育及产量性状,筛选综合性状表现较好的木薯品种,为在生产上推广种植鲜食木薯提供理论依据。【方法】采用田试验方法,以华南205(SC205)为对照,研究不同食用木薯品种SC9、GR891、SC201、沙田木薯、ZM8229的出苗率、生长发育、节点数、节点距、产量、淀粉含量。【结果】SC205(CK)发芽快、出苗早、出苗整齐、出苗率高;SC201生长最快,其次是GR891,最慢的是SC9;SC205(CK)的节点数最多,节点距最短,SC201节点数最少,节点距最长;SC9产量最高,比SC205(CK)增产9.14%,其余品种均比对照低,以沙田木薯产量最低;淀粉含量SC201最高,为30.35﹪,其次是GR891,为30.12%,分别比对照增加32.71%和31.71%。【结论】综合性状表现最好的木薯品种是SC9,其次是GR891和SC201,沙田木薯和ZM8229居中,最差的是SC205(CK)。

摘  要：
【Objective】The growth,yield traits of several edible cassava cultivars was studied to screen cultivars with good comprehensive characters and provide a theoretical basis for the cassava production.【Method】Germination rate,growth,number of nodes,length of internodes,yield and starch of six cassava varieties including SC9,GR891,SC201,shatian cassava,ZM8229 were analyzed with cultivar South China 205( SC205) as the control.【Result】The results showed that not only the germination of SC205( CK) was the fastest and the earliest but also the germination rate the highest,the SC201 was the highest in growth rate,followed by the GR891,with the SC9 was the slowest during the whole stage of growth and development. The SC205( CK) had the shortest internodes length and the highest number of nodes. SC201 had the longest internodes length and the least number of nodes. The SC9 out yield was the highest,which increased by 9. 14% than the control SC205,and the yield of other varieties were lower than the control SC205,in which the shatian cassava give the lowest. As to starch content,the SC201 was the highest( 30. 35 %),followed by the GR891( 30. 12 %),and which increased by 7. 48 %and7. 25 % than the control SC205,respectively.【Conclusion】According to the evaluation of comprehensive traits,the best variety was the SC9,followed by the GR891 and SC201,shatian cassava and ZM8229,the poorest was SC205( CK).
