NEWS RELEASE
Increasing Grain Yield in Sorghum
MADISON, WI, April 5th, 2010-The size and number of kernels determines the grain yield of cereal crops. These characteristics are interrelated, since genetic variation in kernel size is often compensated by an adjustment in kernel number. This trade-off is associated with the balance between grain demand for available supply of nutrients and water. The mechanisms underlying genotypic variation in potential kernel size and number remain unclear, the relative importance of potential grain size in grain yield improvement remains uncertain.
