Key principles for breeding spring-and-autumn using silkworm varieties: from our experience of breeding 873?874
author
Abstract:
The successfully breeding of the hybrids 873?874 had settled the problem that the yield was not uniform to the silk quality in silkworm varieties. In this paper, we illuminated the key technology, principle, hints and methods for selection in breeding spring-and-autumn rearing silkworm varieties were analyzed using the procedure of breeding the hybrid of 873?874 as example.

full textBreeding for Salt-Resistance Using Transgressive Segregation in Spring Wheat
Hybrid populations (F3) derived from cross between four moderate salt-resistant spring wheat (Triticum aestivum L.) were assessed for transgressive segregation of salt-tolerant genotypes allowing germination and emergence at 350 mM NaCl for 30 days. The achieved Selection intensity was the order of 0.24-0.27 in these segregation populations (22-25 seedlings from 9000 seeds). Assessment of trans...

Objectives to target: This relates to asking ‘Where to go?’, whereas Tools and Strategies below relate to ‘How to get there?’ Breeding objectives describe the type of animal that we might want to develop, or, more commonly, describe the utility of marginal genetic changes in each trait of commercial value. However, there is increasing concern about loss of genetic diversity, both within and b...

A territorial isolation is a danger to the game population, causing deterioration called the inbreeding depression. The typical signs are anomalous body proportions, such as short lower jaw, shortened lifetime, weak physique and lower birth rate. This is caused by low number of game in the community. White colored deer is in the location of the CzechRepublicbred in separation since 18th century...
full text2. Principles of Estimation of Breeding Values
The most obvious piece of phenotypic information we can use to estimate an animal’s breeding value is the animal’s own phenotype. But we can also use information from relatives, such as the sire, the dam, siblings and progeny. Commercial genetic evaluation systems produce EBVs for each animal for all traits of relevance. Such an evaluation is based on a statistical procedure leading to Best Lin...
