| 1. | These forms are highly sterile, as would be expected of triploids and of autotetraploids derived from basic deploids . 这些类型都是高度不育的,正如由基本的二倍体衍生三倍体和同源四倍体一样。 |

| 4. | Studies on the hybrid between autotetraploid sorghum and johnson grass and the subsequent generation 同源四倍体高粱与约翰逊草杂交及其后代表现 |
| 5. | The correlation analysis between amylose content and agronomic traits of autotetraploid rice 同源四倍体水稻直链淀粉含量与农艺性状的相关性研究 |

| 7. | Development and character observation of autotetraploid polyembryonic mutant rice induced by ion beam implantatioon 离子注入后同源四倍体多胚苗突变水稻的筛选及其遗传稳定性 |
| 8. | And the regenerated tetraploid and its diploid were different in inheritance . by the upper research , the best induction method of pepper polyploid and appropriate concentration and periods of colchicines were obtained . the acknowledge of polyploid was deeper via the morphological and cytological examination and peroxidase isozymes 通过以上研究,我们得到了辣椒同源四倍体诱导的最佳方法和秋水仙碱的最佳处理浓度和处理时间,并从过氧化物同功酶变化,辅以形态解剖学观察、染色体鉴定,综合分析,对多倍体的认识更加深入细致。 |
| 9. | In some cases the observed segregation ratios even allowed us to clearly determine that m . xiaojinesis is a autotetraploid plants , at least is a isosyndetic allotetraploid . these were the cases of 32 m . xiaojinesis - specific markers and 50 markers present in both parents , which fit 5 : 1 and 11 : 1 ratio respectively . since these cases happened were owing to m . xiaojinesis ' s duplex loci 50个双亲共有标记和32个小金海棠特有标记分别适合11 : 1和5 : 1的分离系数,由这两个系数可以推测,小金海棠可能是同源四倍体,至少是同源异源四倍体,因这两个系数都表明其产生是源于小金海棠的双式位点。 |
| 10. | The authors discovered four peculiar phenomena , i . e . , the self seed - setting and its genetic stability of the autoteraploid rice , the early - generation stabilization in the cites between alloploid rices , the self embryogenesis of autoteraploid rice wider isolated conditions , and a high seed - setting percentage in some plants of autotetraploid rice after the treatment of ion beam , in the research of autotriploid and autotetraploid rices 在对同源三倍体水稻和同源四倍体水稻的研究中发现了值得注意的4种奇特现象,即同源三倍体水稻的结籽现象及其倍性的遗传稳定性、在异倍性水稻间的杂交后代中早世代性状稳定遗传的现象、在隔离条件下同源四倍体的胚自发现象和离子束注入后同源四倍体水稻单株的高结实现象。 |
