目的我省为甜菜新产区,近年来甜菜生产迅速发展,种子远远不能满足需要,每年必须大量从外省调运,不仅耗费量大,而且品种类型多,易混杂,使我省甜菜块根含糖率有下降的趋势。因此,研究在我省自然条件下,甜菜种株开花特性,对甜菜杂交育种,繁殖优良品种是有重要的作用。 Purpose The province is a new sugar beet production area. In recent years, the production of sugar beet has been developing rapidly. The seeds are far from meeting the needs. Each year, a large number of seeds must be transported and transported from other provinces. Not only the consumption is large, but also the types of varieties are mixed. Rate of decline. Therefore, studying the flowering characteristics of sugar beet species under natural conditions in our province plays an important role in the crossbreeding and breeding of sugar beets.
