春、秋两季菜薹新品种多点比较试验

Muti-point Comparative Experiment on New Cultivars of Chinese Flowering Cabbages in Spring and Autumn

为选育出优质、丰产、适应性强及抗性好的杂交菜薹新品种,利用自交不亲和系或雄性不育系为母本进行杂交新品种选育,育成了粤薹1号、粤薹2号2个杂交新品种,并以油绿802菜薹为对照,对2个新品种的产量、主要农艺性状、品质以及抗性进行比较和分析。结果表明:粤薹1号菜薹主薹质量最大,为423.4 g,春、秋两季667 m^(2)产量分别是1 028.7、2 718.3 kg,均排名第1;粤薹2号菜薹次之;品质方面,粤薹2号最优,其次为粤薹1号。综合看来,粤薹1号、粤薹2号菜薹株型好、品质优、产量高,是适合出口和内销的优良品种,可以在广东省及周边地区广泛种植。

In order to breed new hybrid cultivars of Chinese flowering cabbage with high quality,high yield,strong adaptability and good resistance,two new hybrid cultivars ’Yuetai No.1’ and ’Yuetai No.2’ were bred by using self-incompatibility lines or male sterile lines as female parent.The yield,main agronomic characters,quality and resistance of the two new cultivars were compared and analyzed with the cultivar ’Youlü 802’ as control.The results showed that the main moss weight of ’Yuetai No.1’ was 423.4 g,and the yield in spring and autumn was 1 028.7 kg per 667 m^(2)and 2 718.3 kg per 667 m^(2),respectively,ranking first in both seasons,’Yuetai No.2’ was followed.In terms of quality,’Yuetai No.2’ was the best,followed by ’Yuetai No.1’.In general,’Yuetai No.1’ and ’Yuetai No.2’ had good plant type,excellent quality and high yield,which were suitable for export and domestic sales.These two cultivars could be widely planted in Guangdong province and surrounding areas.
