| 摘 要： | 本文分析了１６个水稻籼型（或籼粳中间型）光温敏不育系、两个光温敏不育系的杂交组合后代花粉育性、自交结实率与包颈长度的关系．结果表明，水稻籼型（或籼粳中间型）光温敏不育系的不育性与包颈长度呈极显著的相关，即包颈长度越大，不育度越高．根据包颈长度判断花粉育性程度可作为水稻籼型（或籼粳中间型）光温敏不育系田间选择的重要参考指标．

Study on the relationship of fertility and stem clasping length of Photo/temperature genic male sterile of indica rice ( Oryza sativa L.). |

| Abstract: | The relationship of pollen fertility, sel seed setting rate and stem clasping length of 16 photo/temperature sensitive genic male sterile lines(P/T GMS) of indica rice and two hybrid combinations derived from 2 P/T GMSEes were analyzed. The result indicated that obvious co relationship was found between fertility of P/T GMS and stem clasping length,namely the lengther of clasping stem, the higher the fertility rate.Therefore,judging the fertility rate accord stem clasping length,it will be used as an important index to select P/T GMS of indica rice in the field. |
