为了评价用甘蓝型油菜雄性不育系与红菜薹杂交培育适于华南种植的耐热红菜薹杂交种的可行性,研究了甘蓝型油菜雄性不育系117AB与红菜薹配制的5个组合(即186-1-96A/十月红,186-1-96A/优选十月红、186-1-96A/二早子、186-1-96A/改良十月红、186-1-96A/湘研菜薹)的叶色、伸展叶数、菜薹产量、经济效益以及甘红杂种增产的原因.结果表明,甘红杂交组合186-1-96A/十月红不仅在全生育期(4个月)内每667 m~2产量可达791 kg、产值达3 164元,且其叶色接近红菜薹,具有广阔的开发的景;甘红杂种能增产,除了其具有杂种优势外,主要是由于其对高温不敏感,生育期较长,出叶速度较慢,背养生长期较长.

In order to evaluate the feasibility of breeding hot resistant Purple Tsai-tai hybrids whether was suitable for South China by the cross between Brassica napus male sterile line and Brassica campestris, the leaf colour, leaf number, yield, output value and yield-increasing of 5 combines (186-1-96A/Shiyuehong, 186-1-96A/Youxuanshiyuehong, 186-1-96A/ Erzaozi, 186-1-96A/ Gailiangshiyuehong, 186-1-96A/Xiangyancaitai) were studied. The results showed that the yeild and output value of 186-1-96A/shiyuehong reached 791 kg and 3 164 yuan per 667 m~2, respectively. And the leaf colour was close to Brassica campestris.The reason for yield increasing of the combinations was mainly due to its high temperature resistance, longer growth period, slow-grow leaves, longer vegetative growth stage, except the heterosis.
