The role of root architecture and associated rhizosphere interactions in breeding for weed competitive wheat cultivars
I aim at identifying below ground traits to link these to the above ground traits, known to impact the competitive ability such as greater early leaf development; larger penultimate flag and flag leaves; greater tillering; taller planophile canopies in order to deliver understanding toward an ideotype of a competitive wheat.
I will be looking at root development, and allelopathy in controlled and field environments under rain-fed and irrigated conditions during the growth of the wheat plant, through sampling, washing and measuring the root systems of different wheat cultivars, historical cultivars and unique germplasm
