多倍体甜菜品种具有丰产、产糖量高、工艺品质好等特点,在高肥、足水的条件下,更能充分发挥其种性,在生产实践中具有较大的生产潜力。目前,我国甜菜生产上单产较低的情况下,推广多倍体甜菜新品种,可提供更多的原料来满足制糖工业生产发展的需要。二倍体甜菜经过人工诱变,使细胞内染色体加倍成为四倍体,再与相应的二倍体杂交成为三倍体,这种细胞染色体数目的改变,导致了内部生理结构和经济性状的改变,称之为多倍体甜菜。我所经过十年的努力,于1976年培育出第二批多倍体甜菜新品种:双丰305、双丰306、双丰307,1970年开始试配组合,经过六年田间试验、品种比较及
Polyploid beet varieties with high yield, high sugar content, good process quality and other characteristics, under the conditions of high fat, enough water, give full play to their species, in production practice has greater production potential. At present, under the condition of a low yield of sugar beet production in our country, the promotion of new varieties of polyploid beet can provide more raw materials to meet the needs of sugar industry production and development. Diploid beet has been artificially mutated to double the number of intracellular chromosomes to tetraploids and then hybridize with the corresponding diploids to become triploids. Changes in the number of such cells lead to changes in internal physiology and economic traits , Called polyploid beet. After ten years of hard work, I cultivated the second batch of new varieties of polyploid beet in 1976: Shuangfeng 305, Shuangfeng 306 and Shuangfeng 307, and began the trial combination in 1970. After six years of field trials, and
