报道了在棉花自花授粉后，利用花粉管通道将０．５ｍｍｏｌ／ＬＮａＮ３直接导入鲁锦６号的胚囊中，在变异后代中，采取系统选择的方法，选育出了一个早熟品系，它的熟期比鲁棉６号提前２５天，并且性状稳定。经过时鲁棉６号和早熟株系进行ＲＡＰＤ分析，结果表明，ＮａＮ３可以引起后代ＤＮＡ序列的广泛变异，并且棉花基因组可能存在着诱变剂作用的热点。
Reported that after self-pollination of cotton, 0.5 mmol / L NaN 3 was directly introduced into the embryo sac of Lujin 6 by means of pollen tube passage. In the mutant offspring, a precocious strain was bred by systematic selection Bilu cotton 6 mature 25 days in advance, and stable. The results of RAPD analysis showed that NaN3 could cause extensive variation of DNA sequences of offspring, and there might be hot spots in the cotton genome for mutagens.
