Grain weight of genotypes of triticale (X Triticosecale Wittmack) in agroecological conditions of Banja Luka [Bosnia and Herzegovina]

Grain weight is a genotypic characteristic that is directly related to the realization of yield. Analysis of average grain weight was performed in ten genotypes of winter hexaploid triticale (Trimaran, Ticino, Odisej, Agrano, BLT21, BLT17, BLT10, Max 1793, Bogo and Tornado). Experiment was conducted during 2005/06, 2006/07, 2007/08. in Trapisti, region Banja Luka. During the experiment of winter triticale standard agricultural practice was applied. Microclimatic conditions during triticale cultivation in 2006 and 2008. were relatively similar, while in 2007. there was drought period occurrence. Statistical analysis of observed genotypes for the specified parameter was performed with method analysis of variance 10x3. Analyses of significant differences were done by using LSD test, while interactive effect was analyzed by graphical method. The average weight of triticale genotypes grain regardless of the year showed highly statistically significant differences, while in observation of years regardless of the genotype showed mutually statistically significant differences. Analysis of these relationships was observed through the interaction effects as a final evaluation of the observed genotypes. Based on the average values of the grain weight, winter triticale genotypes were evaluated. The average grain weight of triticale genotypes in the observed years showed the lowest average weight in 2007 (0.0369 g), while the highest grain weight was obtained in 2006 (0.0406 g). Statistically significant difference of the average grain weight of the observed genotypes of triticale regardless of the year showed that genotypes Bogo (0.0465 g), Odisej (0.0453 g) and BLT10 (0.0424 g) were those of the highest average grain weight without significant differences between them. These genotypes were evaluated as potentially proproductive genotypes under the agroecological conditions of Banja Luka.
