Question

what are the desirable agronomic characteristics for crop improvement​

Answer 1

These are:-

Higher Yield

Improved Quality

Biotic and Abiotic resistance

Change in maturity duration

Wider adaptibility

Desirable agronomic characteristics.

better size of grain

high nutritional value

early maturity of the crops

disease, drought resistant crops etc.

Tall branching plants in case where leaves are to be utilized (for example, fodder crops that are grown to feed farm animals).

Short plants in cereals so that nutrition is not consumed by plants to grow taller.

Answer 2

Desirable agronomic characteristics for crop improvements are:      

(a) Tallness and profuse branching are desirable characters for fodder crops.        

b) Dwarfness is desired in cereals, so that less nutrients are consumed by these crops.
