Taking care to prevent the biotic factors (diseases, insects and nematodes) andabiotic factors (drought, salinity, waterlogging, heat, cold and frost) that can affect the crop growth. Acclimatization 3. Plant breeders take this further by cross-pollinating plants (manually placing pollen from one plant on the stigma of another) that have desirable characteristics, harvesting the resulting seed, and selecting new individuals that have combined desirable traits from both parents. Looks like you’ve clipped this slide to already. Cross-pollinating plants that are similar cannot result in continued improvement. Early farmers did this simply by saving seed from those plants they thought had good characteristics. Genetic Engineering. Crop variety improvement: It can be done either by hybridisation or by introducing a gene. Two of them are as follows: Better quality: There are different reasons for improving the quality of different crops, such as improvement of the baking quality in cereals like wheat.
