甘蓝型黄籽油菜主要品质性状与环境效应基因型差异研究

Study of Genotype Discrepancy between Main Quality Characters and Environment Reciprocity in Yellow-Seeded Rapeseed (Brassica napus L.)

以8个不同来源的甘蓝型黄籽油菜基因型为材料,研究了4种不同密、肥(氮素)处理条件下粒色及其它主要品质性状的变化。结果表明:不同来源的甘蓝型黄籽油菜基因型,其粒色等品质性状存在极显著差异;甘蓝型黄籽油菜的品质性状主要决定于基因遗传效应,同时密肥效应和基因型与密肥的互作效应对甘蓝型黄籽油菜的品质也有极显著影响。不同基因型甘蓝型黄籽油菜的品质性状在密肥处理间变异程度不同。

The seed color and other main quality characters of eight yellow-seeded rapeseed （Brassica napus L.） genotypes were studied in 4 different planting density and nitrogenous fertilizer treatments .The results showed that there are significant difference in seed color and other main quality characters of different genotype yellow-seeded rapeseed （Brassica napus L.）. The main quality characters of yellow- seeded rapeseed （Brassica napus L.） were mostly determined by the genotype. Planting density, nitrogenous fertilizer and the interaction of them have significant effects on the main quality characters. The variation of the main quality characters of different genotype yellow-seeded rapeseed （Brassica ncrpus L.） is different to the planting density and nitrogenous fertilizer treatments.
