Study of the Influence of Cultivar and Biological Seed Category on Winter Wheat Production

Abstract

Wheat is one of the most cultivated agricultural species alongside corn and rice. In this study, we tested the influence of cultivars and seed biological class on yield in winter wheat. As a comparison, we used two Romanian varieties, Dropia and Faur, and two foreign varieties, Apache and Bercy in field-testing under normal agronomical practices. Data obtained in field trails was statistically processed by Duncan test for multiple comparisons between tested variants. Results indicate that yield decreases according to the seed biological class. Furthermore, the analysis of the distribution of significance differences in production, it resulted that both the cultivar and the biological category of the seeds act individually and combined on the average yields of winter wheat. Since the assortment of varieties in winter wheat is one that is renewed every year, and as a result of the fact that farmers have the option of multiplying the seed of autogamous varieties for their own use, we believe that the obtained results can be useful in evaluating the productive potential of winter wheat crops sown with seed from certified generations C1 and C2 or from subsequent generations of multiplication, which are not subject to the official certification process.
