Statistical differences between means were determined by oneway analysis of variance (ANOVA) followed by Duncan's test.
The statistical differences between the means were determined using a two-tailed paired Student's t-test.
The differences between means were determined by Tukey's test at P < 0.01 and 0.05.
The differences among means were determined using the post hoc Tukey test.
Differences between the means were determined using one way analysis of variance (one way ANOVA) followed by Bonferroni's test.
Trial means were determined from eight randomly selected plants in the middle of the rows of all lines.
Comparison of the diets was analyzed using one-factor analysis of variance (ANOVA), and the differences between diets' means were determined by Duncan multiple range tests (Duncan, 1955).
The data were analyzed using analysis of variance (ANOVA) and significant differences (p < 0.05) among means were determined by R commander software.
SPSS 18 (SPSS Statistics 18.0, SPSS Institute, Inc., Chicago, IL, 2010, USA) was used for one-way analysis of variance and canonical correlation analysis (CCA), and significant differences (P < 0.05) among means were determined by the least significant difference test.
Significant differences in group means were determined using t-tests.
When significant differences were indicated, differences between means were determined by Dunnett's multiple comparison test.
