The relative variability of corn crosses and varieties
1932
Arnold, L.E. | Jenkins, M.T.
It is a matter of common observation that corn varieties, single crosses, inbred-variety crosses, and double crosses differ in their relative variability. The present investigation was conducted to determine the differences in the amount of variability of varieties and these three kinds of crosses as measured by the standard deviations and coefficients of variation for various characters. The characters studied were plant height, ear height, total number of nodes, number of nodes below the upper ear, and number of kernel rows on the ears. Only the heights and numbers of nodes above the soil surface were measured or counted.
