Application of Selection Concepts for Genetic Improvement

چکیده
How Genetic Improvement Is Achieved To obtain genetic improvement, the breeding value of the animals must be estimated from the phenotypes (that which can be observed or measured) of the animals themselves and (or) those of their relatives. The phenotypes may be performance records on the prospective replacement stock, performance records on the relatives of the prospective replacement stock, or a visual evaluation of the animals or their relatives. Visual evaluation is not recommended for traits which can be measured.

متن کاملEvaluation of genetic parameters in agro-physiological traits of wheat (Triticum aestivum L.) under irrigated condition
Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...
