Assessment of Yield Attributes and Industrial Quality Parameters of Oat Cultivars (Avena sativa L.) Using Multivariate Techniques (PCA, PLS-DA and OLS-R)

Abstract

Triazoles and strobilurins group of fungicides have been reported to have dual properties (growth regulator and fungicide) and have been used to prevent the plant lodging. In this study four subsequent field experiments with oat cultivars with and without fungicide application were conducted from 2012 to 2015 aiming to find if fungicide application can improve some yield attributes and quality parameters of oats and find yield attributes that most affect the quality parameters of oats. Multivariate techniques were applied in other to find the most important variables that contribute to sample classification. Fungicide application has a role in reducing the plant stature of oat cultivars with consequent decreasing in lodging index of oat cultivars. Fungicide

“…Thousand-grain weight is an important parameter because higher grain yields can be achieved from the same number of embryos, only with the increase in reserves accumulated in the grain depends on up or bottom position of oat panicle (Mut et al, 2018). Uarrota et al (2017a), studied 21 white oat cultivars, with and without application of fungicide and found differences between URS Guria and URS Brava for important industrial traits, like thousand grain weight, sieve grain index and hectoliter weight. According to Schulz et al (2013) grain production in different wheat genotypes depends on the adjustment of yield components, number of tillers per plant, number of grains per spike and grain weight.…”
