Abstract

Twenty hop genotypes were selected for the evaluation of resistance to primary and secondary Pseudoperonospora humuli infection and of alpha acid and hop oil content in the hops. From the wild hop genotypes, two from Canada and one from Belgium showed resistance. Among the registered hop varieties, the Czech varieties Kazbek and Boomerang were the most resistant. Both wild hop genotypes from Canada showed the highest content of alpha acids among the wild hop entries, namely 4% w/w. The lowest variability of the alpha acid content in the wild hop category was found in two wild hop varieties from the Caucasus, one from Austria and one from Lithuania. The highest content of hop oils was determined in two hop genotypes from Canada and two from Belgium. Wild hop genotypes from the Caucasus have the lowest variability of hop oils among the wild hop entries. Two hop genotypes from Canada and one from Belgium were selected for breeding aimed at drought resistance.

葎草遗传资源对腐殖质假假性孢子虫的抗性及酒花中α酸和酒花油含量的测定。

选取20个啤酒花基因型，测定其对腐殖质假假盘孢菌的初级和次级抗性以及啤酒花中α -酸和啤酒花油的含量。从野生啤酒花基因型来看，来自加拿大的两株和来自比利时的一株显示出抗性。在已登记的啤酒花品种中，捷克品种哈兹别克和回力棒的抗性最强。来自加拿大的两种野生啤酒花基因型的α -酸含量最高，为4% w/w。野生啤酒花中α -酸含量变异最小的品种是高加索地区的两个野生啤酒花品种，一个来自奥地利，一个来自立陶宛。两种来自加拿大的啤酒花基因型和两种来自比利时的啤酒花基因型的啤酒花油含量最高。来自高加索的野生啤酒花基因型在野生啤酒花条目中具有最低的啤酒花油变异性。选择来自加拿大的两种啤酒花基因型和来自比利时的一种啤酒花基因型进行抗旱育种。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
