为筛选适应在武平种植的双季晚稻品种,武平县十方镇引进试种了泰优656、天优596、两优842、谷优1186共4个杂交水稻新品种。4个新引进的水稻品种均比对照品种汕优46有不同程度的增产,其中产量较高的泰优656和谷优1186比对照增产均达极显著水平。

Four later rice varieties were introduced and planted in Wuping country, and Shanyou 64 was considered as a control. The results showed that Taiyou 656 and Guyou 1186 showed high and stable yield, which had wide popularizing prospect.

[目的]调查8个蓝莓品种在天津地区的适应性。[方法]以引进的8个蓝莓品种为试材，从植株性状、结果枝类型、物候期、果实经济性状、丰产性等方面进行调查分析。[结果]在合理改良土壤的基础上以上几个品种均可以适应天津的自然气候，基本体现出品种自身的生长特性。B、D、E、F、G品种适应性强，口感佳，可作为鲜食品种在露地条件下种植；A、H品种成熟期早，果实品质优良适宜设施栽培，而 C品种口感略酸可作为加工品种种植。[结论]为其它相近生态条件的地区开展蓝莓引进、选择和栽培利用，提供一定的理论参考依据。

Objective The aim was to research the adaptability of 8 blueberry species in Tianjin. [Method] With 8 blueberry species as materials, blueberry was explored in terms of plant characters, the type of fruit-bearing branch, phenological phase, fruit economic characters, and yielding capacity. [Result] Al blueberry species were suitable to be grown in Tianjin with improved soils, showing blueberry growth characters, without any virus or diseases. General y speaking, species B, C, D, E, F and G can be grown in soils exposed to the air as fresh food; species A and H are suitable to be cultivation; species C tastes sour, which can be planted for fur-ther production. [Conclusion] The research provides references for blueberry intro-duction, selection, and cultivation in the region with similar ecological characters.

本文对河北省油用亚麻育种历程进行了回顾,从育成品种应用推广、核心种质资源引进和利用、抗病和丰产育种目标提升、育种方法研究以及项目完成、成果奖励、人才培养等九个方面总结了育种成就;从杂交亲本遗传基础、育种测试手段、品种选育方法、育成品种适应性等四个方面指出存在不足;并从育种目标的准确定位、种质资源挖掘和引进、提高育种测试手段和培育具有广泛适应性抗病高产优质品种四个方面提出来今后育种工作方向。

This paper reviewed the breeding history and experiments of oil flax in Hebei province , 9 breeding achievements were summarized , including application and promotion of varieties , introduction and utilization of germplasm resources , improvement of disease resistance and high -yield breeding tar-gets, research on breeding theory and methods , as well as projects completed , awards and talents culti-vation.And 4 shortages were pointed out , including the hybrid parent genetic basis , breeding test meth-ods, variety breeding methods, variety adaptability, and so on.Directions for the future were brought up based on the following factors , including determination of breeding target , excavation and introduction of germplasm resource , improvement of detection means and development of adaptable varieties with disease-resistant, high-yield and good quality .

采用灰色关联度分析方法,对11个从荷兰引进的观赏菊花品种的主要性状进行了综合分析评价,并对所引进的品种主要性状与理想性状进行等权与加权关联度分析。结果表明:等权关联度大小依次为:romanovBretagneml.yellowKastelliAmadeaJeanny pinkRadosVenniceBacticaBiarritcpp.golden。加权关联度大小依次为:romanovBretagneml.yellowKastelliAmadeaJeanny pinkVenniceRadosBacticaBiarritcpp.golden。即romanov的综合表现最好,其次为Bretagne和ml.yellow,这3个品种适合在昆明地区大力推广种植。

The comprehensive analysis and evaluation on the main characters of 11 ornamental chrysanthemum varieties intro-duced from Holland were carried out , and the equal -weight and weighted correlation degrees between their main characters and ide-al characters were analyzed by using the method of grey correlation degree analysis .The results indicated that the equal -weight cor-relation degrees of various varieties had the following order: romanov>bretagne>ml.yellow>Kastelli>Amadea>Jeanny pink >Rados>Vennice>Bactica>Biarritc>pp.golden .The weighted correlation degrees showed the following sequence:romanov>bret-agne>ml.yellow>Kastelli>Amadea>Jeanny pink >Vennice >Rados>Bactica >Biarritc>pp.golden.Thus, romanov had the best comprehensive performance , followed by bretagne and ml .yellow.These three varieties were suitable to be planted in Kunming district.

为了引进抗腐烂病新品种，调整云南苹果品种结构，需要对新拟引进品种抗性进行鉴定。以目前主栽品种红富士作为对照，通过观察果园自然发病程度和人工接种腐烂病原菌进行抗性鉴定相结合，对苹果品种对腐烂病的抗性进行鉴定。结果表明，这些测试的苹果新品种对苹果树腐烂病的抗性均存在差异，云南6个苹果新品种对腐烂病的抗性均比主栽品种红富士强。其中斯维塔、玉华早富对腐烂病的抗性表现较好，其次为新嘎啦、短枝富士、皇家嘎啦和金世纪。通过鉴定，明确这些品种均为云南未来可以推广使用的抗腐烂病的新品种。

For importing new apple varieties into Yunnan and adjust apple variety structures ,new apple varie-ties imported were need identified their resistance to Valsa Canker .Combining analysis of the investigation of natural infection incidence in orchards and incidence of artificial inoculation ,resistance to Valsa Canker in six apple varie-ties planted in Yunnan were evaluated with Fuji as a control .The results indicated that those varieties showed differ-ent resistant to Valsa Canker .All of them showed more resistant to Valsa canker than Fuji .Yuhua Early Fuji and Si-weita showed the highest resistant to Valsa canker following by Gala ,spur Fuji ,Royal gala and Golden century .With identification ,make sure that those varieties can be used as resistant vaieties to Valsa canker in Yunanan .
