The major results are as follows. 1. A genetic linkage map containing 150 SSR markers was constructed based on an F2 population with 500 individuals.
主要结果如下：1。以500个F 2单株为作图群体，利用150个共显性的SSR标记，构建了覆盖玉米全基因组的分子标记连锁图。
The main agronomic traits in three transgenic hybrid F2 populations and one non-transgenic hybrid population have been examined using "bulked segregation" method.
利用“集团分离法”对三个转基因杂交F_2群体和一个非转基因杂交F_2群体的主要农艺性状进行了考察。
The heterozygote genotypes in F2 population in this type of species are different from those in general species in which the genetic recombination occurs in meiosis of both male and female.
这类物种的杂交F2群体中杂合子基因型的与一般物种中雌雄个体的减数分裂细胞都发生遗传重组的F2群体杂合子表型不同。
The effects of interval mapping for quantitative trait loci(QTL) of single trait under different heritabilities and marker densities in a F2 population were compared by computer simulation.
采用计算机模拟方法系统比较了目标数量性状的遗传力和标记密度对F2设计下单个性状数量性状座位（QTL）区间定位效果的影响。
Permanent group competitive advantage was negative, so this immortalized F2 population could not be directly used theoretically in production, but it could be used as genetic group research materials.
永久群体的竞争优势为负向，理论上此永久F 2群体不能在生产上直接利用来作为杂交亲本，但可以作为遗传群体的研究材料。
Permanent group competitive advantage was negative, so this immortalized F2 population could not be directly used theoretically in production, but it could be used as genetic group research materials.
永久群体的竞争优势为负向，理论上此永久F 2群体不能在生产上直接利用来作为杂交亲本，但可以作为遗传群体的研究材料。
