Objective: To evaluate ten triticale genotypes to assess the quality of the seeds under two production systems, with cut and without cut, in the municipalities of Matamoros (L1) and Francisco I. Madero (L2), Coahuila,Mexico.
Design/Methodology/Approach: The agronomic variables evaluated were: Grain yield (GY), number of seeds per spike (NSS), spike length (SL), number of spikelets per spike (SS) and plant height (PH). Variables in the laboratory were: normal seedlings (NS), abnormal seedlings (AS), seeds without germinating (SWG), dry seedling weight (DW), plumule length (PL) and radicle length (RL). Statistical analysis was performed with the PROC ANOVA procedure, of the SAS software.
Results: A higher grain yield was found for Matamoros (L1) compared to Francisco I. Madero (L2); however,for the variable number of seeds per spike it was higher in the latter (L2). For the physiological quality of seeds in L2, the highest values were in the variables normal seedlings and radicle length. In the comparison of production systems, the best response was for the system without cut in both locations; therefore, good quality triticale seed can be produced with acceptable grain yield.
Study Limitations/Implications: It is necessary to describe the performance of triticale in the springsummer agricultural cycle in the central region of the country.
Findings/Conclusions: The productive performance of triticale genotypes was variable depending on the production system, and there was also a different effect on the physiological quality of the harvested seed
