Two method of plant breeding-:
Selection -:It is most ancient and basic procedure in plant breeding. It generally involves three distinct steps. First a large no. of selections were made from distinct .second progeny rows are grown from individual plant selection. after making several experiments finally the selected inbred lines are compared to existing commercial variety in their yielding performance.
polyploidy : Most plants are diplod. plants with three or more chromosomes are common and are referred to as polyploids .The increase of chromosomes sets per cell can be artificially induced by the chemical colchisine which leads to doubling of the chromosomes number. The main effect of polyploids is increase in size and genetic variability.
