Fig. 1

Frequency distribution of trait per environment in the GP X Otis recombinant inbred line (RIL) population. Values represented mean of each RIL. Parental values for each trait were indicated by arrows. X-axis represents the probability density estimation of the frequency of lines. Data obtained in each environment considered were indicated above each plot. For example, 2018BT and 2019BT represents biotron (BT) grown barley plants for year 2018 and 2019 respectively, while 2020ID represents field grown barley plants in Idaho for year 2020. Traits measured in those environments were indicated in brackets. A-C represents seed weight, D and E represents shoot dry weight, while F and G represents protein content
