the factors for which variety improvement is done
Factors for which variety improvement is done are:
a)Higher yield - This involves the increase in the productivity of the crop per acre in order to sufficiently feed the growing population.
b)Improved quality - Improvements in quality are aimed to maintain the quality of crop plants (nutritional factors).
Quality depends on the type of crop, for e.g. baking quality of protein in pulses, quality (colour, taste) of oil from oil seeds.
c)Biotic and abiotic resistance- Biotic like insects and abiotic factors like water logging salinity, drought, heat, cold and frost have a negative impact on crop production. A crop resistant to these factors gives a better produce.
d)Change in maturity duration - Short duration crops reduce cost of crop production. Uniform maturity makes harvesting easy.
e)Wider adaptability - Such a trait is desirable as the same crop variety can grow in varied conditions.
