| ABSTRACT Seven genotypes of canola in two consecutive years 2019 and 2020 in a randomized complete block design with four replications were carried out at Mansoura special farm and 10 traits were measured. Correlation coefficients were computed between the seed yield and its related attributes. The genotype by trait (GT) biplot graph was used to compare genotypes based on multiple traits. The results of the experiment showed that there were significant differences among genotypes for all studied traits. The Serw 4 was superior in all traits followed by Line 1055.Highly significant and positive correlation was recorded between seed yield/plant and each of plant height, fruiting zone length, 1000-seed weight,and highly significant and negative correlation was recorded with days to 50% flowering but without significant with oil percentage. The obtained results by GT biplot graphs were coincided with those obtained by correlation matrix showing that GT biplot graph is considered a successful and effective technique beside or instead of these analyses. Undoubtedly, GT biplot graph is preferred because it is easy to interpret and gave more information. | ||||
