前言生产上利用杂交棉是棉花增产的重要途径之一。棉花为常异花授粉作物,在自然条件下是以自花授粉占优势的,但常因蜜蜂采蜜而发生生物学混杂。因此,及时对高优势组合的亲本做好防杂保纯工作是非常必要的。自交是保纯的重要手段,但自交对棉花后代发育影响如何呢?为此,我们采用了人工控制下的自交方式,研究自花授粉对棉花的自交当代和自交一代的籽棉发育的影响。 Introduction The use of hybrid cotton production is one of the important ways to increase cotton production. Cotton is an evergreen pollination crop that is dominated by self-pollination under natural conditions, but is often biologically confused by bees collecting honey. Therefore, it is necessary to do a good job of preventing and cleaning up the parents of high-performing combinations in time. Selfing is an important means to preserve purity, but how does selfing affect the development of cotton progeny? To do this, we used a self-pollination method under artificial control to study the effects of self- Developmental effects.
