Crop variety improvement

  1. 1. Crop Variety Improvement
  2. 2. Crop variety improvement Crop Variety Improvement depends on finding a crop variety that can give a good yield. This is done by hybridisation. Hybridisation is the crossing between genetically dissimilar plants to obtain crops having useful characteristics like disease resistance,good- quality and high yields. Hybridisation may be intervarietal (between different varieties) Interspecific (between two different species of the same genus) or intergeneric (between genera). Another way of improving crop variety is by introducing a gene to obtain the desired caracteristic.This produces genetically modified crops.
  3. 3. Higher Yield: To increase the productivity of the crop per acre. Improved quality: Quality considerations of crop products vary from crop to crop. Baking quality is important in wheat, protein quality in pulses, oil quality in oilseeds and preserving quality in fruits and vegetables. Biotic and Abiotic resistance: Crops production can go down due to biotic and abiotic stresses under different situations.Varieties resistant to these stresses can improve crop production. Change in maturity duration: The shorter the duration of the crop from sowing to harvesting,
  4. 4. The more economical is the variety.Such short durations allow farmers to grow multiple rounds of crops in a year. Short Duration also reduces the cost of crop production.Uniform maturity makes the harvesting process easy and reduces losses during harvesting.  Wider adaptability: Developing varieties for wider adaptability will help in stabilising the crop production under different evironmental conditions. One variety can then be grown under different
