通过整理提纯并按已制定的繁殖技术规程所繁殖的原原种(原种繁殖群体,下同)和原料(制种母本群体,下同)的不育率均可在较高水平上保持高度稳定,分别可达到49.8%-50.6%和49.1%-49.8%;其异形株率原原种可控制在0.17%-0.5296,原种可控制在0.38%-0.52%;初花整齐,原种从第一株初花到全部植株开花可控制在25天以下,其中95.3-99.6%的植株初花在15天的延续期内。用所繁殖的原种配制的杂交种油研五号在大面积生产上所生产的商品菜籽的芥酸含量可稳定在1.2-1.24%,含油量可稳定在39%左右,其杂交种丰产性和抗性得到了稳定并略有增强,多年来大面积平均产量在1884.0-1957.5kg/hm2,这说明达到了连年保持所配杂交种的产量优势和增产潜力.并稳定其优良品质的目的。
The sterility rate of the original seed (original breeding population, the same below) and the raw materials (seed breeding female population, the same below) which are purified and purified according to the established breeding technical regulations can be maintained at a relatively high level Highly stable, respectively, up to 49.8% -50.6% and 49.1% -49.8%; the original strain can be controlled at 0.17% -0.5296, the original species can be controlled at 0.38% -0.52%; the first flowering neat, the original species from the first flowering to flowering of all plants can be controlled at 25 days or less, of which 95.3-99.6% of the plants early flowering in 15 days During the extension. Hybrid seed oil prepared by the breed of the original research on the 5th large-scale production of commercial products rapeseed erucic acid content can be stabilized at 1.2-1.24%, oil content can be stabilized at about 39% Its hybrid yield and resistance have been stabilized and slightly enhanced, over the years a large area of the average yield of 1884.0-1957.5kg / hm2, which shows that the hybrids to maintain the annual production of hybrid yield and yield potential. And stabilize the good quality of its purpose.
