چکیده مقاله:
Sorghum is one of the most important crops grown for human diet and bio-energy. An understanding of genotypes efficiency by evaluating multivariate methods like genotype by traits (GT) and genotype by yield×trait (GYT) biplot is essential to detect suitable genotypes of sorghum. Therefore, traits interrelationship of eighteen sorghum genotypes were investigated based on a randomized complete block design with three replications during ۲۰۱۶-۲۰۱۷. The data of various characters were subjected to ANOVA, Pearson correlation, the GT and the GYT biplot analysis via SAS and GGE biplot software. The analysis of variance depicted that there were significant differences among Genetype×Year interaction based on evaluated variables (P>۰.۰۱). The evaluation of traits and their association by GT and GYT biplot indicated that there were significant (P>۰.۰۰۱) differences among traits and yield-trait combination which was strongly approved by numerical Pearson correlation. Also, the GT biplot indicated that the best-ranked genotypes included G۴>G۱۵>G۶>G۱۷>G۱۸>G۱۶>G۱۳>G۳ and the GYT biplot superiority-ranked genotypes compris-ed of G۴>G۶>G۱۷>G۳>G۱۵>G۱۰>G۲>G۷>G۱۱. Both the GT and GYT biplot confirmed that FGCSI۰۴ (G۴) was the most suitable and ideal genotype strongly suitable to sorghum production according to prominent performances on plant height, panicle length, panicle width, grain yield and biological yield. This genotype evaluation showed that there were existed a high genetic diversity among genotypes for the studied variables in which GT and GYT approach simultaneously can help breeders to select prominent genotypes and reduce genetic load in the breeding programs.
