| Abstract: | Summary The variation of the two parameters, harvest index and grain/straw-ratio, has been theoretically compared by applying the relative measure coefficient of variation. The harvest index exhibits a clear superiority (= lower variation) compared to the grain/straw-ratio.Applications to ten European winter oilseed rape cultivars and lines are in an excellent agreement with the theoretical findings. |
