Note(s) : Genetically uniform cultivars in many self-pollinated cereal crops dominate commercial
production in high-input environments especially due to their high grain yields and
wide geographical adaptation. These cultivars generally perform well under favorable
and high-input farming systems but their optimal performance cannot be achieved on
marginal/organic lands or without the use of external chemical inputs (fertilizers,
herbicides and pesticides). Cereal breeding programs aim at evaluating candidate lines/cultivars
for agronomic, disease and quality traits in a weed free environment that makes it
impossible to identify traits conferring competitive ability against weeds. Moreover,
quantification of competitive ability is a complex phenomenon which is affected by
range of growth traits. Above (e.g. light) and below (e.g. water and nutrients) ground
resources also influence competitiveness to a greater extent. Competitiveness is quantitatively
inherited trait which is heavily influenced by many factors including genotype, management,
environment and their interaction. Sound plant breeding techniques and good experimental
designs are prerequisites for maximizing genetic gains to breed cultivars for organically
managed lands. The brief is focused on breeding wheat for enhanced competitive ability
along with other agronomic, genetic and molecular studies that have been undertaken
to improve weed suppression, disease resistance and quality in organically managed
lands. The examples from other cereals have also been highlighted to compare wheat
with other cereal crops
