A study of the correlation of the characters of barley

Abstract

This study is made for the purpose of finding whether correlations are present in various characters of barley and also for the study of correlation in general. Until recently practically nothing has been done along this line, especially with barley. However, we find some attention has been paid to the correlation of nitrogen content, mealiness, color of grain and paleae, length and thickness of internodes, fineness of hull, average weight per kernel, and length of head. Most of this was done before the modern statistical method was introduced.
