四倍体品系选育是甜菜多倍体育种的中心环节。近年来,由于甜408、334等四倍体优良品系选育成功,培育出了诸如甜研301、甜研302、协作二号等优良甜菜多倍体品种,为了丰富四倍体品系材料,使多倍体育种有新的突破,几年来坚持“优中选优”的原则,依据多项指标在优良系内进行了较广泛的选择,形成了优良品系系列。为了从解剖、生理角度对这些品系作进一步测试,检验生理选择的效果,我们于1991年对几个四倍体系列进行了几项形态及解剖生理指标的测试,并与经济性状的关系作了分析,结果如下.
Tetraploid strains breeding is beet polyploidy breeding center. In recent years, due to the success of tetraploid sweet line selection such as sweet 408,334, polyploid varieties of sweet beet such as sweety 301, sweetyan 302 and No. 2 were developed. In order to enrich the tetraploid lineage material, New breed of polyploidy breed, the past few years adhere to the “excellent choice of the best” principle, according to a number of indicators in the Department of Excellence conducted a wider range of choices, formed a series of fine lines. In order to further test these lines anatomically and physiologically, and to examine the effect of physiological selection, we conducted several morphological and anatomical and physiological tests on several tetraploid lines in 1991 and compared them with the economic traits Analysis, the results are as follows.
