鄂北地区近年小麦倒伏现象频发,部分年份倒伏面积大且倒伏程度大,严重影响小麦灌浆成熟,降低穗粒数、千粒重,造成小麦产量损失甚至是大幅减产.当地小麦倒伏现象易在灌浆期前后发生,倒伏越早对产量影响越大,如抽穗期、灌浆前倒伏主要影响粒数和粒重,可减产30％～50％,灌浆期倒伏主要影响粒重,一般减产达20％左右,因此防止小麦倒伏是目前当地实现小麦高产、稳产的重要生产措施.

按照国家小麦产业技术体系要求,收集湖北全省主栽小麦品种和耐湿、抗穗发芽品种资源,在2011-2013年2个生产年度试验的基础上,筛选、鉴定适合鄂北麦区栽培的小麦耐湿、抗穗发芽高产稳产品种.结果表明,襄麦25和襄麦55两个品种耐渍(湿)、抗穗发芽能力及高产稳产性较强,可以作为鄂北麦区小麦耐湿、抗穗发芽的首选品种.

分析小麦倒伏主要种类及倒伏原因,提出生产上防止倒伏的对策。

According to the investigation and analysis on yield and component factors of three wheat(Triticum aestivum L.) cultivars,Zhengmai 9023,Xiangmai 55 and Xiangmai 25 during 2009～2012,effective spike number had the most significant positive correlation with actual production(path=0.412 5);1 000-kernel-weight was the second(path=0.2872);while grain number per spike had the lowest(path=0.151 7) correlation.The results of correlation analysis and path analysis were consistent.The variation coefficient of 1 000-kernel-weight during different year was the highest,followed by effective panicle;the lowest was of grain number per spike.In order to reach the maximum yield,the breakthrough should be realized on increasing the grain number and 1 000-kernel-weight based on the optimum effective spike number,and coordinate the relationship among the three indexes.

紫甘蓝是从国外引进的一个结球甘蓝的生理小种,是结球甘蓝的三个变种之一。紫甘蓝具有普通结球甘蓝适应性广、较耐寒和耐热、产量高、营养丰富、耐贮藏运输等特点,还由于其叶球是紫红色的,鲜艳诱人,所以特别受到消费者的青睐,目前,从紫甘蓝中提取的天然色素在食品加工和饮料生产中用途广泛。随着国内外市场对紫甘蓝色素需求量的加大销售前景广阔。

<正>襄麦55是湖北省襄樊市农科院作物所以高代品系7019(组合为8811/贵农24-7)与鄂麦19杂交后经系谱法选育而成的中筋小麦新品种。2009年8月通过湖北省农作物品种审定委员会审定,品种登记号为鄂审麦20090010

小麦温光敏雄性不育是杂种优势利用的重要部分.而小麦温光敏雄性不育受遗传和环境等因子影响,遗传机理较为复杂,因此,探讨小麦温光敏雄性不育机制及不育基因的控制方式对其利用极其重要.文章介绍了小麦温光敏雄性不育类型、生理生化研究、遗传学研究及分子生物学等方面的研究进展,并对小麦温光敏雄性不育选育策略及利用前景进行了讨论.

根据2008年小麦条锈病苗期发病动态,结合我市小麦品种布局及近期气候条件,分析我市2009年小麦条锈病流行趋势,并从小麦条锈病防治的整体战略角度,提出了扼制小麦条锈病流行为害的综合防治措施。

Xiangmai 25, a novel moderate gluten wheat cultivar, was developed from the progenies of hybridization between two wheat cultivars (the dwarf male-sterile wheat Tai1062 and the normal wheat Emai 19) by using pedigree method in Xiangfan Academy of Agricultural Sciences. It was named by the appraisal committee of crop variety of Hubei province in 2008. It had wide adaptability in all regions of Hubei province and good prospects for application. Its yield, quality and resistance were better than the control cultivar (Zhengmai 9023).
