How Crop variety improvement achieved. |
|
Answer» Crop variety improvement can be achieved by the process of selection. Factors for which variety improvement is done are higher yield, improved quality, biotic and abiotic resistance, change in maturity duration, wider adaptability, desirable agronomic characteristics etc. Hybridisation occurs by a cross between two different varieties, which is known as inter-varietal crossing, or between two different genera, known as inter-generic crossing, or between two different species, known as inter-specific crossing. Crop yield can also be increased by introducing desirable genes into the crop plant. This results in genetically modified crops. |
