对36个水稻骨干系进行了RFLP(限制性内切酶长度多态性)分析,并对这些水稻材料的162个杂交组合育性进行了分组分类研究。
The line Jiao 51 was found with high GCA and higher non-additive gene effect in the hybrids in which Jiao 51 was a parent. Therefore, Jiao 51 was an elite line.结果表明,自交系交51具有较高的一般配合力和其配出的组合易出现较强的非加性基因效应。
Are we not, therefore, in the process of creating a new elite, of drawing a new line to divide the world between those who have access to communication and knowledge, and those who are left out?因此,我们究竟是在创造一个新的精英阶层,还是在给世界划分一条新的界线,把拥有通讯和获取知识条件的人与无法获得这些条件的人区分开来?
