The primary goal is to find crop varieties that can give a good yield.
Hybridisation refers to the crossing between genetically dissimilar plants to incorporate desirable characteristics.
The types are intervarietal (between different varieties), interspecific (between different species of the same genus), and intergeneric (between different genera).
A genetically modified crop is one that has had a gene introduced to provide a desired characteristic.
It is important to ensure that the variety can thrive in varying climates and soil conditions, making it useful for farmers in different areas.
Good quality seeds ensure that all seeds are of the same variety and germinate under the same conditions, leading to better crop yield.
Unpredictable weather conditions such as drought and floods can negatively impact crop yields, making it essential to develop resilient crop varieties.
Biotic stresses include diseases, insects, and nematodes that can reduce crop production.
Abiotic stresses include environmental factors such as drought, salinity, water logging, heat, cold, and frost that can negatively impact crop growth.
Higher yield increases the productivity of the crop per acre, which is economically beneficial for farmers.
Improved quality varies from crop to crop, focusing on factors like baking quality in wheat, protein quality in pulses, and oil quality in oilseeds.
Shorter maturity duration allows farmers to grow multiple rounds of crops in a year, reducing production costs.
Uniform maturity simplifies the harvesting process and reduces losses during harvesting.
Wider adaptability means developing varieties that can stabilize crop production under different environmental conditions.
Tallness and profuse branching are desirable agronomic characteristics for fodder crops.
Dwarfness is desired in cereals because it helps reduce nutrient consumption by these crops.
By developing varieties that can withstand varying climatic conditions, crop variety improvement can help mitigate the impacts of climate change on agriculture.
Crops that respond well to fertilisers can enhance yields, making them more effective for farmers.
Soil quality directly affects crop yield, as nutrient-rich soil typically leads to better crop growth and productivity.
Incorporating desirable characteristics helps improve the resilience, yield, and overall quality of crops, making them more viable for farmers.
