Viégas, G. P.
The State of São Paulo imports straw of Sorghum for its broom industry when this material could be satisfactorily produced in the State. The principal hereditary defects of the broom-corn which could be eliminated to a certain extent by selection are goose neck panicles, twisted panicles and stemmy panicles. Various introduced varieties were subjected to comparative field tests along with a local variety which came years ago from Argentine. This variety superseeded all the others when subjected to selection. All the lineages derived from it when tested with the primitive and recently introduced stock revealed far superior in many respects. Seeds of these lineages were turned over to the competent Department of the Instituto Agronómico to be increased in guantity and then distributed to farmers. In this work the X² test is recommend for analysis and interpretation of the results.
