| 摘 要： | 通过形态比较、细胞学观察、性亲和力测定,以及酯酶同工酶分析,研究了爪哇稻与云南高原粳之间的亲缘关系。结果是:爪哇稻与云南高原粳之间,在一些性状上表现出重叠变异现象;细胞学观察表明杂种F_1的花粉母细胞减数分裂基本正常;爪哇型内的布鲁稻品种对某些云南高原粳品种、布鲁稻和云南高原粳品种分别对普通粳稻、以及云南高原粳类群内的性亲和力相当高;在定量分析下,二者表现出相类似的酯酶同工酶的遗传物质基础。根据本研究结果,初步认为爪哇型内的布鲁稻与云南高原粳之间的亲缘关系较密切。本文还讨论了爪哇稻的分类地位和酯酶同工酶基因与调节体系等问题。

| Abstract: | Observations and analysis were made in morphology, cytology, sexual affinity, and esterase isozyme. Between the Javanica and the King types cultivated in Yunnan, the overlapping variation was found in some characters. Meiosis of pollen mother cells was regular in F_1 hybrids. The sexual affinity between two types was determined. Under fixed quantity, both types showed the similar genetic material relative to the esteras isozyme. The results showed that there existed a close relative relationship between the Bulu variety and the King type cultivated in Yunnan. The subjects on the position of Javanica type in classification, the genes of esterase isozyme, and the regulative system were also discussed. |
