不同类型油莎豆品种的群体质量特征与产量表现

Population Quality Characteristics and Yield Performances of Different Types of Chufa Varieties

对10个油莎豆品种2 a的群体质量特征与产量表现等数据进行了统计分析,结果表明:根据千粒重、株型及块茎分布等表现可以将油莎豆分为两大类型、4个小类型,即大粒型品种(包括普通大粒型、特大粒型)和小粒型品种(包括小粒型、中粒型);产量构成因素上,单穴粒数、总粒数均表现为小粒品种显著高于大粒品种,而千粒重方面则表现为大粒品种显著高于小粒品种;2个品种类型的块茎均比较集中,且小粒型品种集中度高于大粒型品种。

Two years experimental data of 10 chufa cuhivars, such as population quality characteristics, yield performances and so on, have been statistically analyzed. The results showed that according to 1000-tuber weight, plant types and the distribution of tuber, the chufa can be subdivided into two types： small tuber type and large tuber type, which also can be divided into four parts in detail： small tuber type, medium tuber type, large tuber type and super large tuber type; the tuber number per hole and the total tuber number of the small tuber type varieties were significantly higher than that of the large tuber type varieties, but the 1000-tuber weight of the large-tuber type varieties was significantly higher than that of the small tuber type varieties; the tubes of both type varieties were all concentrated, and the small tuber type varieties was more concentrated than the large tuber type varieties.
