Effects of ten years organic and conventional farming on early seedling traits of evolving winter wheat composite cross populations.

ABSTRACT: Early vigour traits of wheat composite cross populations (CCPs) based on high yielding (Y) or high quality (Q) or Y*Q varietal intercross evolving under organic or conventional conditions in parallel populations were studied hydroponically. To eliminate storage and year effects, frozen F₆, F₁₀, F₁₁ and F₁₅ seeds were multiplied in one field, resulting in the respective F_x.1 generations. This eliminated generation and growing system effects on seed size for the F_6.1 F_10.1 and F_15.1. Due to a severe winter kill affecting the F₁₁, the generation effect persisted, leading to larger seeds and markedly different seedling traits in the F_11.1 compared to the F_10.1 and F_15.1
