| 摘 要： | 试验以14个全国苦荞品种为材料,进行籽粒产量相关性状的分析,结果表明,主要相关性状对籽粒产量影响的顺序为:株高>主茎节数>出苗日数>单株粒重>单株粒数>现蕾至开花天数>生育日数>千粒重>出苗至现蕾天数>一级分枝。籽粒产量与开花至成熟天数关系不密切。增加株高、主茎节数、单株粒重、单株粒数是增加籽粒产量的主要途径。选择大粒和提高现蕾至开花天数是提高籽粒产量的重要途径。通过增加出苗至现蕾天数和一级分枝数可间接提高籽粒产量。出苗天数增加可导致籽粒产量减少。

| Abstract: | Fourteen tartary buckwheat were used in this study to conduct a analysis on some characters relevant to grain yields.Among the eleven characters observed,the sequense of their role on grain yields was as follows:plant height>nodal numbers of main stem>days of seedling>plant grain weight>plant grain numbers>days of squaring to flowering>days of growing>thousand kernel weight>days of seedling to squaring>numbers of first branchy stem.Between grain yields and days of flowering to ripening was small relations.G... |
