Measurements of the central culm and head of 256 plants of Marquis wheat were made in 1919 , which were called "mother heads" and "mother culms' ' respectively. Each head was threshed separately and an equal number of kernels from each, sown in nursery rows with the seed from long heads alternating with that from short heads. The same order of planting was followed during the length of the experiment. Each row was threshed separately and seed saved for the following year.
