Abstract:

Field trial with wheat varieties Perfekta, KG 56S, Aleksandra and Vizija was set on vertisol-type soil during the vegetation season 2010/11 and 2011/12. The aim of the research was to analyse the yield and grain yield components in four varieties of wheat cultivated on acid soil. The highest values of yield components and grain quality were established in the year with moderate temperatures and high precipitation in the vegetation year 2010/11. The KG 56S and Vizija varieties had the highest yield of grain, the highest number of plants and spikes per m2. The Perfekta variety showed the highest

Abstract:

Abstract Triticale (x Triticosecale Wittmack) is a cereal used in Argentina as a winter seasonal pasture or feeding grain. Efforts made on breeding have led to varieties with potential grain yield similar or greater than with wheat. The aim of this study was to determine the gene effects, heritability, genetic gain, heterosis and inbreeding depression in various quantitative traits of a cross from contrasting lines of triticale using generation means analysis. The thousand kernel weight was adjusted to a model of additive-dominance, while the rest of the traits exhibited significant epistatic

The effect of European corn borer, Ostrinia nubilalis (Hübner), injury during the spring on yield and yield components of winter wheat, Triticum aestivum L. em Thell, was studied. Spike and grain characteristics of infested and uninfested culms were compared in three fields of ‘Florida 302’ winter wheat in eastern Georgia. Feeding on inner stem tissue by larvae killed the grain spike producing a “white head” symptom in wheat. Most larvae (95.2%) tunnelled in the peduncle which caused an average of 3.4% of spikes to be barren. Larval injury did not reduce spike length but did reduce grain weigh
