Furthermore, their early maturity frees the land quickly, often allowing an additional planting of rice or other crop the same year. Inbred line: It is a relatively true-breeding strain resulting from at least 3 successive generations of controlled self-fertilization or back crossing. That’s called domestication, and it resulted in local varieties that were well adapted to the local conditions. After that point the plant breeder can work with the genetically engineered line in the same manner they work with other parents in their breeding program. Plant breeding is a slow and long process involving several steps and. method of altering the genetic pattern of plants to increase their value and utility for human welfare Smith defined plant breeding as the art and science of improving the genetic pattern of plants in relation to their economic use.
