甘蔗×斑茅杂种及其双亲的农艺、工艺、植物学性状和染色体观察

Observations on the Agronomic,Milling and Botanical Characters and the Chromosome in Commercial Cane × E. Arundlnaceus Hybrid and Its Parents

本研究对甘蔗（ＣＰ６５－３５７）×斑茅的杂种及其父母本进行了植物学性状、农艺性状观察；锤度、含糖量、纤维含量以及染色体数目与减数分裂染色体动态也进行了观察和分析，对甘蔗与斑茅远缘杂交后代的性状遗传、染色体传递和育种利用等方面提出了一些看法。

The paper presents the observations on the botanical and agronomic characters, Brix,con-tents of sucrose and fibre in cane, and the number and perfoimanee of chromosomes in the PMC dur-ing the meiosis in the hybrid of commercial cane × E.arundinaceus, Some ideas about the character in-heritanee,chromosome transmission and breeding utilization of distant hybrid of sugareane×E.arundinaceus are given.
