鄂沙28皮棉产量较高,纤维品质也较好。但种子品质较差,给播种及田间成苗带来一定的影响。分析种子品质不高的原因,可能与品种遗传特性,种子贮藏和处理等因素有关,同时也不可忽视目前种用子棉沿用商业部门的规定,按皮棉的级别作为种子定级标准带来的鱼目混珠现象。因此,我们特于1983-1984年初步探讨了鄂沙28分期采收的子棉级别与种子播种品质的关系,试图为提高鄂沙28种子播种品质提供依据。
E’sha 28 lint yield higher fiber quality is better. However, the quality of the seeds is poorer, which has a certain impact on sowing and field seedling. Analysis of seed quality is not high, may be related to the genetic characteristics of varieties, seed storage and processing and other factors, but also can not ignore the current use of seed cotton business sectors, according to the lint level as a seed grading standards brought fish head phenomenon. Therefore, we tentatively discussed the relationship between the seed cottonseed level and seed sowing quality of E’sha 28 collected in 1983-1984, and tried to provide the basis for improving the sowing quality of 28 seed in E’sha.
