将5个源于桑特拉∥389/marnoo后代的Y2D5(B.napus)黄籽株系及其中3个株系的人工粒选黄籽、褐黄籽分别种植,采用自交、成对互交和开放授粉3种处理。结果表明,在自交、互交条件下,后代的黄籽频率较高;人工粒选黄籽种植,有利于提高其后代黄籽频率;人工粒选黄籽和控制授粉相结合对提高后代的黄籽频率更有效。开放授粉籽粒含油量相对较高,株系间有差异。黄籽皮壳率低于褐黄籽,含油量高于褐黄籽。在育种工作后期阶段,要注重筛选在开放授粉条件下后代黄籽频率高、含油量也高的单株,并进行连续定向选择,有望选育出黄籽高含油量的品种。
Five Y2D5 (B.napus) yellow seed strains derived from Santrac ∥ 389 / marnoo offspring and three artificial grained yellow seed and yellow brown seed from three of them were planted separately and selfed. Pay and open pollination 3 kinds of treatment. The results showed that under the conditions of selfing and reciprocal crossover, the frequency of yellow seed of the offspring was higher. Artificial grain selection of yellow seed was beneficial to increase the frequency of the yellow seed of its offspring. The combination of artificial seed selection and yellow pollination to improve the progenies Yellow seed frequency more effective. Open pollinated grain oil content is relatively high, there are differences between strains. Yellow seed hull rate lower than brown seed, oil content is higher than brown seed. In the later stage of breeding work, we should pay attention to screening single plants with high frequency of yellow seeds and high oil content under the condition of open pollination and carry out continuous directional selection, which is expected to breed varieties with high oil content of yellow seeds.
