Molecular Assisted Breeding and Adaptability Analysis of Zhongyouza 11 with Super High Oil Content

Using a three-line system of Shaan 2A cytoplasmic male sterility, a hybrid variety rapeseed, Zhongyouza 11, was developed by the combination of traditional methods and a molecular marker-assisted breeding technique. This hybrid variety had high grain yield, high oil content, wide adaptability, and good quality. The oil content of Zhongyouza 11 is steadily above 43% in the three ecological regions along the Yangtze River valley, which is the largest winter oilseed production area in China. The highest oil content of Zhongyouza 11 reached 46.68% in the upper reaches of the Yangtze River valley in 2003-2004, which was the highest among all lines involved in the national regional rapeseed variety trials. In the regional yield trials in Hubei Province, the average yield of Zhongyouza 11 reached 2 853 kg ha-1 (2002-2004), yielding more than the control variety Zhongshuang 6 by 11.34%. In the national trials, the yield of Zhongyouza 11 reached 2 405.7, 2 697.3, and 2 770.2 kg ha-1 in the upper, middle, and lower reaches of the Yangtze River valley, yielding more than the control varieties by 11.52, 12.9, and 14.92%, respectively, in 2003-2005. Both the high oil content and high grain yield contributed to the high oil yield of Zhongyouza 11. The oil yield of Zhongyouza 11 in the national trials reached 1083.3, 1210.2, and 1224.8 kg ha-1, yielding more than the controls by 29.42, 27.65, and 20.98%, respectively, in the upper, middle, and lower reaches of the Yangtze River valley. The highest oil yield reached 1369.65 kg ha-1 in the middle reach of the Yangtze River valley(2003-2004), with an increase of 46.21% compared to the control. The experimental sites distributed widely along the Yangtze River valley, cover most of the Chinese winter rapeseed production areas. Among the 89 experimental location/years, the yield of Zhongyouza 11 surpassed the controls at 77 location/years in the trials, indicating its wide adaptability.Zhongyouza 11 was the only one that passed the national regional trials in all three regions along the Yangtze River valley simultaneously in 2005. It is also the first rapeseed variety that contained seed oil exceeding 46% and passed the national regional trials. This study shows that heterosis prediction by the means of estimation of genetic distance between parental lines using single sequence repeat (SSR) and sequence related amplified polymorphism (SRAP) markers is an efficient way for the reduction of tedious field trials and the acceleration of breeding procedure.

 通过杂种优势利用来提高油菜产量的同时提高种子的含油量，从而获得油菜生产最终目标性状--产油量的总体提升是发展高效低成本油菜产业的保证。介绍了利用辐射诱变、有性杂交结合单株成对测交等方法，改良油菜细胞质雄性不育三系的育性、产量和含油量性状，选育高产油量杂交油菜品种中油杂8号的过程及其特性。在湖北省和中国油菜品种区试中，中油杂8号比对照中油821分别增产9.82%和10.64%，达极显著水平；含油量和产油量在湖北省区试中均居参试品种首位，分别达42.77% 和1 051.05 kg·ha-1，比对照品种分别提高3%和161.3 kg·ha-1，是目前长江中游区含油量最高的少数几个优质杂交油菜品种之一。文中还对中油杂8号的强优势基础、增产高油因素及通过大粒性状培育高产油量油菜品种的育种策略进行了讨论。     

高产油菜新品种的鉴定筛选

多点试验对10个油菜品种(含对照)的鉴定和筛选结果表明,产量在品种间、环境(地点)间存在极显著差异,并且还存在品种×地点交互作用.对照中油杂2号产量居第1位,H0302比对照减产2%,不显著,H0301和希望106比对照分别减产3.4%和3.5%,显著.除H0301外,其余品种均达到"双低"标准,其中希望106和H0304品质较优.沪油16、华油1087和希望106综合抗性相对较高;H0302和H0304与对照相比差异显著,为稳定性低的品种,而其余品种与对照相比未达到显著水平.产量性状和单产间简单相关分析和通径分析表明,单产与每角粒教之间呈极显著正相关,千粒重与单株有效角果数之间呈极显著负相关,产量性状对于单产的相对重要性依次为每角果粒数＞单株有效角果数＞千粒重.综合各项数据鉴定筛选出4个高产优质品种,分别为中油杂2号、H0302、H0301、希望106.     

轻简化栽培对甘蓝型油菜品质、农艺性状的影响

[目的]研究轻简化栽培对甘蓝型油菜品质和农艺性状的影响。[方法]对秦优7号在合肥国家区试点、长江下游及中油杂2号在长江中游于正常密度和高密度（正常密度的1.0～1.5倍）下品质、农艺性状进行了比较,并对农艺性状与产量之间的相关性进行了分析。[结果]2008～2009年中油杂2号在长江中游高密度种植时产量比正常密度种植略有减产,而秦优7号在长江下游高密度种植时增产7.31%。[结论]甘蓝型油菜高密度种植对产量影响最大的因子是主花序结角数。主花序结角数可以作为筛选适宜高密度种植高产品种的目标性状。

Breeding of Zhongyouza 8, a Canola Variety with Large Seeds and High Oil Yield

High oil yield resulted from a combination of high grain yield and high oil content is a prerequisite for the high efficient oilseed rape production. By using irradiation induced mutation and sexual hybridization combined with paired test cross, the fertility, yield and oil content of the three lines of cytoplasmic male sterility have been improved and a new hybrid variety Zhongyouza 8 with high oil yield was developed. It has been testified that the yield of Zhongyouza 8 was significantly higher than that of the control variety Zhongyou 821 with 9.82 and 10.64% increase in the regional trials of Hubei Province and nationwide, respectively. The oil content and oil yield of Zhongyouza 8 were the highest among all the lines involved in Hubei provincial trials, being 42.77% and 1 051.05 kg ha^-1 which was raised by 3% and 161.25 kg ha^-1 compared to the control Zhongyou 821, respectively. The genetic basis for the strong heterosis, and the factors contributing to the yield and oil content increase of Zhongyouza 8 as well as the strategy for high oil yielding variety improvement through increasing seed size were also discussed in this paper.

甘蓝型油菜中油杂8号种子纯度的SSR鉴定

细胞质雄性不育三系杂交种的纯度鉴定是油菜种子生产中重要的一环。选用173对SSR引物在中油杂8号的亲本间扩增,从中筛选到6对扩增效果好、条带清晰且差异片断在亲本间能够重复出现的引物,其中P051、P078和P203三对SSR引物在杂种F1中同时表现出父母本的特征条带。用这3对引物对32份中油杂8号的DNA进行鉴定,发现P078和P203的鉴定结果完全相同,因此采用其中的P078引物对经过田间种植鉴定的中油杂8号样品进行了鉴定。结果表明,SSR鉴定的结果与田间种植鉴定的结果非常接近,说明采用P078或P203都可以对中油杂8号进行快速准确的鉴定。
