Agronomic evaluation and physiological quality in triticale, under two production systems in the Laguna Region

Abstract

Objective: to evaluate ten triticale genotypes to evaluate the quality of the seeds, under two production systems with one cut and without cut in the municipalities of Matamoros (L1) and Francisco I. Madero (L2), Coahuila.

Design/Methodology/Approach: the agronomic variables evaluated were:,Grain yield (RG), grains per ear (GPE), ear length (LE), spikelets per spike (EE) and plant height (AP). Variables at the laboratory level were: germination percentage (PG), anormal seedlings (PA), seeds without germinate (SSG), dry weight (PS), plumule length (LP) and radicle length (LR). Statistical analysis was performed with the PROC ANOVA procedure, of the SAS software.

Results: for L1, a higher grain yield, compared with L2, however, for the variable number of grains per ear it was higher in L2. In the physiological quality of seeds for L2, the highest values they were in the variables germination percentage and radicle length. In the comparison of production systems, the best answer was for the system  without  cut in both locations, therefore, good triticale seed can be produced quality with acceptable grain yield.

Study limitations/implications: It is required to describe the behavior of triticale in the spring-summer agricultural cycle in the central region of the country.

Findings/Conclusions: The productive behavior of triticale genotypes was variable depending on the production system, likewise different effect on the physiological quality of the harvested seed.
