Research Notes : Poland : Performance of some important characters of hybrid soybean (F1) in a cool climate

Abstract

<p>Obtaining intervarietal hybrids of Glycine max (L.) Merrill in a cool climate such as in Poland (latitude above 50°N) is one of the most important problems for development and introduction of original cultivars of this species. In 1977, hybrid soybean seeds were obtained for the first time in our Academy through field crossing of various forms (cultivars and PI's). Charac-teristics of some important traits of F1 plants in comparison with their par-ental forms were the subject of this paper.</p>
