improvement in crop yields

Two parents of known well defined characters belonging to two different species within a genus are crossed to achieve heterosis. Some important hybrids (both inter specific and intra specific) are listed ..

Breeding - Crop improvement by deliberate attempt to cross two parents of desirable characters to incorporate such characters in next generations is called breeding. The entire process of pollination, fertilization and regeneration is kept under control and selected parents are ..

Designer Plants - Many years ago, Frederick Steward and his co-workers cultured cells from carrot plants and induced some of them to develop into small embryos. Some of these embryos grew into whole plants. Today, researchers routinely regenerate crops, plants and many other plant species..

Beneficial Mutations - Crop - Reported benefits after mutations Barley - Reduction in height, increased yield and day neutrality Groundnut - Improved oil content Wheat - Grain colour improved Rice - dwarfing, increased yield. In India, g induced mut..

Question: How does mixed cropping increase yield? Answer: The yield is increased due to complementary effect. Example: Legume crops complemented with cereals and other non-legume crops increase the yield..
