实验多倍体,做为提高植物生产率的有效措施,现在已广泛利于糖甜菜育种实践之中。几十个高产的甜菜多倍体杂种,在苏联以及在欧洲所有甜菜生产国的农业生产中,已经大量的推广。与此同时,甜菜育种中实验获得的多倍体类型的利用,面临一系列严重的问题,这些问题的解决将在显著程度上决定育种的进一步成就。首先就是结实性问题,即植株的种子结

Experimental polyploid, as an effective measure to improve plant productivity, is now widely used in sugar beet breeding practice. Dozens of high-yielding sugarbeet polyploid hybrids have been extensively popularized in the Soviet Union and in agricultural production in all beet-producing countries in Europe. At the same time, the utilization of polyploidy types of experiments in beet breeding has faced a series of serious problems whose resolution will to a significant extent determine the further achievements of breeding. The first is a matter of solidity, the plant’s seed knot
