The crop is selected by breeding for various useful characteristics; like disease resistance, response to fertilizers, product quality and high yields. This process can be continued until the plant breeder feels the resulting plants are ready to be sold as a new variety. The Missouri Crop Improvement Association (MCIA) is an independent, not-for-profit organization providing unbiased, third-party inspection, audit and testing services in the areas of seed certification, seed quality assurance (QA), identity preserved grain (IP), source identified native plants and forbs and weed seed free hay/forage. Attempts must be taken to ensure higher yield. Plant breeding, and therefore crop improvement, depends on genetic variation. Crop variety improvement and its effect on productivity: the impact of international agricultural research. CROP VARIETY IMPROVEMENT For this purpose, a crop variety is chosen which can give good yield. Hybridisation is the crossing between genetically dissimilar plants to obtain crops having useful characteristics like disease resistance,good- … This is done by hybridisation. If current trends persist, as many as half of all plant species could face extinction. Plant breeders take this further by cross-pollinating plants (manually placing pollen from one plant on the stigma of another) that have desirable characteristics, harvesting the resulting seed, and selecting new individuals that have combined desirable traits from both parents. The section, crop variety improvement, lays emphasis on various factors for which crop variety improvement is done.

Plant breeders, on the other hand, select those plants that have qualities that are desired by humans: bigger fruit, higher yield, particular flavors (see section on domestication). Tissue Culture 6. Introduction to crop variety improvement The development of improved, fertilizer-responsive high-yielding varieties of wheat and rice during the early 1960s and their widespread adoptions by farmers, first in Asia and then in Latin America, marked the beginning of … Much of the success of this method during the early 1900s depended on the existence of genetically variable land varieties that were waiting to be exploited. This proposed variety is medium erect plant bears height more than 70-75cm. Plant Introduction 2.

It helps in the development of crops with desired traits such as high yields, disease resistance, quality product and response to fertilizers. (iv) Change in maturity duration: Shorter maturity period of crop reduces the cost of crop production and makes the variety economical. Source(s): https://shrinkurl.im/a92JT. Hybridization was first of all practically utilized in crop improvement by German botanist Joseph Koerauter in 1760. Crop Improvement :: Plant Genetics: ... Any progeny superior to an existing variety is then released as a new “pure-line” variety. Mendel onward, the hybridization had become the key method of crop improvement. The loss of biodiversity is considered one of today’s most serious environmental concerns by the Food and Agriculture Organization.
