一、棉花品种经济性状变异的特点 农作物的性状可以分为质量性状和数量性状两类,它们表现的特点和遗传的方式不同。质量性状,例如经典遗传学的创始人孟德尔(1822—1884)所研究的豌豆的红花和白花、种子的圆粒和皱粒、黄子叶和绿子叶等,性状之间区别明显,没有中间类型,表现间断性的变异,比较稳定,不容易受环境条件的影响而改变。数量性状,倒如早期遗传学家所研究的玉
First, the characteristics of cotton varieties of economic traits variation Crops traits can be divided into two types of quality traits and quantitative traits, their performance characteristics and genetic methods are different. Quality traits, such as safflower and white flowers of peas, round and wrinkled seeds of seeds, yellow cotyledons and green cotyledons, studied by Mendel (1822-1884), the founder of classical genetics, differ significantly between traits without intermediate Type, the performance of intermittent variation, more stable, not easily affected by environmental conditions change. Quantitative traits, like the jade studied by early geneticists
