2011～2012年对从美洲引进的15个矮秆蓖麻品种进行物候期、农艺性状和主要经济性状的大田鉴定,选拔可直接应用于生产的优良品种或优异的育种材料。引进的15个品种株高在75.5～89.3 cm之间,其中有7个品种的株高在80 cm以下,为超矮秆蓖麻品种。浙引15号、浙引10号、浙引2号、浙引5号、浙引12号、浙引6号和浙引14号7个品种的蓖麻叶产量为38 773～42 647 kg/hm2,与国内矮秆蓖麻对照品种相仿,而蓖麻籽产量为4 038.0～4 657.5 kg/hm2,均显著或极显著高于对照品种。7个高产品种中,有3个品种的含油率和蓖麻油酸含量高于国内对照矮秆品种。经初步鉴定,上述高产矮秆蓖麻品种的主要农艺性状及适应性优良,是良好的叶、籽兼用型蓖麻品种,进一步多点鉴定后可望直接应用于生产或作为新品种选育材料。
From 2011 to 2012, 15 dwarf castor cultivars introduced from the Americas were field-identified by phenology, agronomic traits and major economic traits. The selection could be directly applied to the production of fine varieties or excellent breeding materials. The plant height of the 15 cultivars introduced was between 75.5 and 89.3 cm, of which 7 cultivars had plant height below 80 cm, which was an ultra dwarf castor cultivar. The output of castor leaves from 7 varieties of Zhejiang lead 15, Zhejiang lead 10, Zhejiang lead 2, Zhejiang lead 5, Zhejiang lead 12, Zhejiang lead 6 and Zhejiang lead 14 was 38 773 ~ 42 647 kg / hm2, which is similar to the domestic dwarf castor varieties, while the castor bean yield is 4038.4 ~ 6565.5 kg / hm2, both significantly and extremely significantly higher than the control varieties. Among 7 high-yielding varieties, 3 varieties had higher oil content and ricinoleic acid content than domestic control dwarf varieties. After preliminary identification, the above-mentioned high-yield dwarf castor varieties are excellent in agronomic traits and adaptability and are good varieties of both castor leaves and seeds. Further multi-spot identification is expected to be applied directly to production or as a breeding material for new varieties .
