Two pairs of sister lines of hexaploid triticale (X Triticosecale Wittmack) differing by the presence (++) or absence (-) of telomeric heterochromatin on chromosome arms 7 RL (cv. Drira) and 6 RS (cv. Rosner) were used in order to study the effects of telomeric heterochromatin loss on twelve agronomic traits, The following multivariate statistical techniques were used : multivariate analysis of variance, partial correlation, multiple regression analysis and canonical correlation, The loss of telomeric heterochromatin was accompanied by significant changes in the means of the twelve traits as a whole as evidenced by the results of the multivariate analysis of variance and in the regression of yield on the other traits. Many more partial correlation coefficients were changed in the Drira lines than in the Rosner lines; most coefficients became larger in the Rosner line lacking heterochromatin while the opposite was true in the corresponding Drira line, The traits most affected differed from cultivar to cultivar, There were also changes in the regression of seed yield on the other traits with number of spikes contributing significantly only in the lines lacking telomeric heterochromatin with a concomitant loss of the significant contributions in these lines of spike length, number of spikelets per spike and the derived variable spike density. It is concluded that the loss of telomeric heterochromatin has significant effects on the expression and the relationships between agronomic traits and groups of traits in hexaploid triticale and that for some traits these effects can be cultivar and chromosome specific. |
