甜菜选育的生理指标及其实践

Physiological Breeding Indexes and Its Application in Sugarbeet Breeding Practice

通过多年研究,确立了反映甜菜品种特性的选育生理指标,初步建立了甜菜生理指标选育新品种的程序,并通过系统的生理选择、组合、鉴定,从而培育出丰产、高糖、品质好、抗逆性强、适应性较广的新品种、新组合、新品系,为甜菜生理育种开辟了新途径。

Physiological indexes reflecting.The characteristics of sugarbeet varieti-es had been determined and a general procedure used for sugarbeet breedingbased on physiological indexes had been established after several yearsresearch.Varieties,combinations or lines with high yielding capacity,highsugar content,high resistance to stresses and wider adaptability had beenproduced by the systematic selection,combination and identification procedure.A new approach for sugarbeet physiological breeding was proposed.
