培育更富有营养价值和工业价值的高产品种,是加拿大今后油菜育种的目标。前几年向这一目标前进的速度是相当快的,特别是在改进营养成分方面进展是显著的。由于育种上具备了三个主要条件,油菜遗传性的改变就有了可能。其主要条件是:(1)油菜及其相近的亲缘中,有益性状的变异很丰富;(2)对重要的经济性状有了快速而准确的测定方法;(3)在大量分离的种子和植株中有丰富的材料可用于试验和选择。 Breeding higher-yielding varieties that are more nutritious and of industrial value is the goal of future rapeseed breeding in Canada. A few years ago to this goal is very fast forward, especially in improving the nutritional content of the progress is significant. Because of the three main conditions for breeding, genetic changes in rape have been made possible. The main conditions are as follows: (1) There are abundant variations of beneficial traits in rapeseed and its relatives; (2) Rapid and accurate determination of important economic traits; (3) In a large number of isolated seeds and plants There is a wealth of materials available for testing and selection.
