ASSESSMENT OF SOME CANOLA GENOTYPES BASED ON GENOTYPE BY TRAIT (GT) BIPLOT ANALYSIS

Abstract: This investigation was conducted at Giza Research Station, Agricultural Research Center (ARC), during 2016/17 and 2017/18 growing seasons, to study the behavior of eight canola genotypes including four promising mutants population, three French cultivar and one Local variety (Serw 4). A randomized complete block design with four replications was used. Correlation coefficients were computed between grain yield and its related attributes as well as factor analysis. The genotype by trait (GT) biplot graph was used to compare genotypes based on multiple traits. Results revealed significant differences among genotypes for all studied characters. The inbreed line 1055 was superior in all characters flowed by inbreed line 1056 and Mutant 39. Highly significant and positive correlation was recorded between seed yield/plant and each of days to 50% flowering, plant height , first racemes height , fruiting zone Length, number of racemes /plant , 1000- seed weight (g) but without significant with oil percentage. Factor analysis divided the studied variables into three factors that contributed (77.30%) of the total variability. First factor included, days to 50% flowering, first racemes height and fruiting zone Length that accounted for (31.34%) of the total variability. Second factor consisted of plant height, number of racemes /plant and 1000-seed weight that accounted for (29.78%) and the third factor endued only oil percentage that accounted for (16.18%) of the total variability. The obtained results by GT biplot graphs were coincided with those obtained by correlation matrix indicating that GT biplot graph is considered a successful and effective technique beside of these analyses. Undoubtedly, GT biplot graph is preferred because it is easy to interpret and gave more information
