Grain weight of genotypes of triticale (X Triticosecale Wittmack) in agroecological conditions of Banja Luka

Abstract

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 productive genotypes under the agroecological conditions of Banja Luka. [Projekat Ministarstva nauke Republike Srbije, br. TR-31092

Grain yield and its components in triticale grown on a pseudogley soil

“…Klimatski uslovi su naročito važni tokom nalivanja zrna, jer nedostatak vlage i visoke temperature tokom ovog perioda utiču na smanjenje mase 1000 zrna (Przulj et al, 2014), što potvrđuju i rezultati ovih istraživanja. Na značajne razlike u masi zrna tritikalea nezavisno od godine, kao i značajne razlike između godina nezavisno od genotipa, takođe ukazuju Kondić et al (2012).…”

Variability of grain weight per spike in wheat grown in different ecological conditions

“…To achieve a desirable combination of traits, breeders have developed methods for creating new high-yielding cultivars, based on extensive crossing and testing of early generation progenies. The increase in grain yield is possible through increasing values of yield components: spike traits, efficiency of photosynthesis and use of nutrients (Knežević et al, 2012). The increasing capacity of spike traits responds to environmental factors, such as temperature values, precipitation, nutrition (Petrović et al 2008).…”

“…Grain weight spike -1 is positively correlated with spike weight and total grain yield (Okuyama, 2005). Moreover, breeding wheat for improved capacity of the morphological and anatomical structure of plant and organs contributes to increasing grain weight spike -1 in selected cultivars (Kondić et al, 2012).…”

Economic importance of use of pesticides in wheat production

“…The aims of agricultural production are increasing yield and quality of crops and reducing losses (Knezevic et al, 2017). Improved crop management based on selection of high yielding genotypes, improved soil fertility by application of fertilizers, irrigation, application pesticide contributed to increasing of yield in agricultural crops (Paunovic et al 2009;Kondic et al, 2012). However, in diverse agro-ecosystems the crop production conducted under pressure of biotic and abiotic limited factors (pests, insects, rodents, drought, frost, high and low temperature air, etc.)…”
