It has been observed that infill percentage has major contribution i.e. 92% towards peak elongation, 91% towards break elongation and 80% towards yield stress.
Weed biomass played a major role as a nutrient source in MT systems and contributed towards yield stabilization and improvement in soil quality.
With insight as to the pathways that might be independently manipulated, and ideas as to the effect of environmental factors on the velocity in each path, one can move towards yield and productivity objectives.
Additional fixation of carbon due to exclusion of ambient UV-B was channeled towards yield as there was a decrease in the level of UV-B absorbing substances and an increase in soluble proteins in all the four plant species.
Key genes with tissue- and developmentally-specific expression have been identified which would be prime targets for genetic manipulation towards yield improvement in bread wheat breeding programmes, utilising TILLING and MAS strategies.
