Decoding the genetic basis of floret fertility in wheat
A high grain yield is undoubtedly a desirable trait in cereal crops. Floret fertility is a key factor which determines the number of grains per inflorescence of cereals such as bread wheat or barley. Nonetheless, until recently little was known about its genetic basis. Whilst investigating floret fertility, a group of researchers have now discovered the locus Grain Number Increase 1 (GNI1), an important contributor to floret fertility. A writeup from Science Daily of an international collaboration, including researchers from the Robert H. Smith Faculty of Agriculture, to decode the genetic basis of floret fertility in wheat. The research was published in PNAS:
