What are the major biotic & abiotic factors effecting wheat grain/flour quality?
Please suggest factors which needs to be addressed.
I suggest to you these papers:-

Dear Mr. Khan,
Practically, all biotic and abiotic factors affect wheat grain and thereby flour quality. Especially directly grain effect factors such as sunn pest, aelia, smut and head blight impact grain and flour quality.
Dear Mr. Khan, it is very general question and you need to read quality in toto through guided texts. Wheat quality is very broad term. It depends on the quality for a given property such as based on its end use and of course it is having genetic basis for quality parameter per se as well as interactions of other abiotic parameters which can influence the development of grain and its maturity. In fact lodging at grain filling stage adversely affect most of the quality traits. Besides terminal heat stress lead to shrinkig of grains and apparently increase protein to starch ratio. Biotic stresses on the contrary can influence quality by contaimantion of aflatoxins and other toxins, bunts and smuts can devastate quality by destroying the endosperm.
Thank you Naresh Kumar Bainsla ,
Actually I want to study the effect of different fungal diseases on wheat grain, flour and bread making quality.
Could you please suggest list of important traits/analyses which needs to be done in such type of studies?
Dear Mr. Khan sir abiotic factors mainly influence the grain/seed development along with it also affects the crop maturity and flowering synchronization whereas biotic factors mostly affects the nutritional quality of wheat. The diseases like kernel bunts and smuts greatly influence the nutritional attributes.
Among the abiotic stress are drought and heat during the development stage that affect adversely grain filling and soundness of the grain.
As for the biotic factors, the kernel bunt, loose and cover smuts are found
Although, extreme heat and drought could be important factors affecting the grain quality but the most important factor is the pre-harvest sprouting (PHS) and seed dormancy. PHS is a critical quality issue affecting many areas of wheat production, especially in an environment characterized by summer rainfall and high humidity.
Mr. Khan sir,
Draught and heat plays a crucial role in gain quality during its growth and development stages. Seed size can be influenced by high temperatures during kernel filling stage, due to higher respiration rates and affects many other qualitative losses in the flour quality along with 3 – 4% loss in yield/°C rise over 15°C. and biotic factors mostly affect the nutritional quality of wheat grain.
in addition to the biotic abiotic factors (heat and temperature, a major threat to wheat production among biotic factors is disease caused by both fungi and fungi-like pathogens.
