| 摘 要： | 为了研究我国新疆白灵侧耳自然种群的遗传多样性,估测自然种群的遗传丰度,对51株新疆野生白灵侧耳的84个原生质体单核体的交配型因子进行分析。在84个单核体中存在54个不同的A因子和59个不同的B因子。x2检测表明交配型因子A和B的系列因子均为等概率分布。据此估算我国白灵侧耳自然群体中有79个A因子,100个B因子,自然群体中的单核交配型总数79×100=7,900个,双核交配型总数31,201,050个。可见,新疆白灵侧耳遗传多样性丰富,新疆是我国白灵侧耳的野生种质资源宝库。 |

| Abstract: | In order to investigate the genetic diversity and estimate the genetic abundance of natural populations of Pleurotus eryngii var. tuoliensis, mating type factors in 84 protoplast monokaryons derived from 51 isolations collected from Xinjiang were analyzed. There were 54 different A factors and 59 different B factors in the 84 monokaryons. Chi-square test indicated that A and B factors were distributed with equal probability. Therefore there would be 79 different A factors and 100 distinct B factors in natural populations of P. eryngii var. tuoliensis in Xinjiang, China, and the putative mating type factors from monokaryon are 7,900, and for dikaryon, there would be 31,201,050 in nature. In conclusion, genetic diversity of P. eryngii var. tuoliensis is very high in Xinjiang, and Xinjiang is a valuable wild P. eryngii var. tuoliensis germplasm resource pool. |
