Environmental Conditions and Genotype Influence Upon Some Correlations Value to Few Lines of Winter Wheat

Abstract

Twenty-five mutant/recombinant lines and the two parental forms of winter wheat were taken into study to assess the correlations between grain yield and some quality traits. This investigation was carried out at ARDS Caracal of University of Craiova, during 2015-2018 cropping seasons in randomized blocks design with 3 replications. It included two factors: A– influence of climatic conditions (2016-2017 favorable conditions (A1); 2017-2018 less favorable (A2) and 2018-2019 abnormal conditions (A3) and b – genotype. Observations were recorded after harvest for grain yield and some quality traits every year after harvest. All the analyzed traits such as proteins, starch, TKW, seeds number/ear, seeds weight/100, seeds weight/ear indicate the experimented material combine well high level of yield and superior quality percent in the grains.

Effect of Climatic Conditions on Wheat Starch Granule Size Distribution, Gelatinization and Flour Pasting Properties

“…Bread wheat (Triticum aestivum L.) is identified as one of the world's most important cereal crops and it is cultivated around the world in diverse environments which can affect productivity and quality. It is predicted that the demand for wheat will increase by 50% until 2050, so the identification of wheat varieties of acceptable yield and constant technological traits is of high importance for breeders [1]. It has long been recognized that wheat quality varies considerably as a result of the genotype, environment, which plays a major role in the expression of the genotype, as well as the interaction between genotype and environmental conditions [2,3].…”
