Experimental Study on Glutinous Variety Improvement of Maize Population Yuzong 5

The representative samples were selected from Yuzong 5,and the methods of field planting and indoor measuring were employed for investigation and data processing on 894 plants of Yuzong 5.The results showed that the coefficients of variation about some traits of 894 plants were as follows: ear height(19.9%); panicle weight(35.1%); ear length(18.1%); ear row number(19.7%); number of kernels per row(22.5%); grain weight per panicle(36.3%); ear diameter(11.1%).It was found that there was large variation in these traits for various plants which could represent Yuzong 5 for glutinous variety improvement.

豫综5号糯质化改良取样可行性分析

[目的]分析豫综5号糯质化改良取样的可行性,明确选取的样品是否具有代表性。[方法]采用田间种植、室内测量等方法对豫综5号的894个单株进行调查和数据处理。[结果]894个单株穗位高变异系数为19.9%,单穗重变异系数为35.1%,穗长变异系数为18.1%,穗行数变异系数为19.7%,行粒数变异系数为22.5%,单穗粒重变异系数为36.3%。[结论]这些性状在各单株之间变异比较大,能够代表豫综5号进行糯质化改良。

《元世祖出猎图》流传考略

台北故宫博物馆藏刘贯道《元世祖出猎图》(轴)是一幅以描述元世祖忽必烈游猎活动为主题的蒙元宫廷画,颇为著名,一直备受蒙元史及美术史学者关注。然而关于这幅图像的历史流传过程,目前却很少有人探讨。本文从书画流传史的角度对《元世祖出猎图》做了一番考证,通过将文献资料与图像相结合,首次指出钱宰《临安诗集·题藩王出猎图》、顾复《平生壮观·元裕宗御容》及纳兰揆叙撰《益戒堂诗后集·题元世祖岀猎图》所涉内容皆指今本《元世祖出猎图》,这为今后研究美术史及蒙元游猎制度奠定文献学基础。
