The objective of this study was to investigate the importance of maternal genetic effects on postweaning performance traits of Yorkshire, Landrace, Duroc, and Hampshire breeds of swine. Data consisted of performance test records collected in a commercial swine operation from 1992 to 1999. Boars from 60% of the litters were culled at weaning based on a combination of maternal and performance ind...

Concerns have been raised regarding selection against the boar taint compounds, androstenone and skatole, due to potential unfavorable genetic correlations with important male fertility traits (i.e., selection of boars with low levels of these boar taint compounds might also reduce male fertility). Hence, the objective of this investigation was to study the genetic association between direct me...

to evaluate the genetic diversity in sardari bread wheat landrace, purification and selection of lines with good agronomic traits, were carried out for ten cropping seasons (1995-2006) in maragheh and six other dryland agricultural research stations. one hundred and six individual spikes were selected among sardari landrace in the first phase of study (1995- 2000). results of morph-physiologica...

in order to evaluate the effects of harvesting dates on qualitative traits of safflower genotypes, an experiment was carried out under field conditions in the agricultural faculty of urmia university in 2009-10. factorial experiments were based on randomized complete blocks design with four replications was used under field condition. genotypes included isfahan landrace, sina, il111 and pi25053...

The term "landrace" has generally been defined as a cultivated, genetically heterogeneous variety that has evolved in a certain ecogeographical area and is therefore adapted to the edaphic and climatic conditions and to its traditional management and uses. Despite being considered by many to be inalterable, landraces have been and are in a constant state of evolution as a result of natural and ...

Muscle growth is regulated by the homeostatic balance of the biosynthesis and degradation of muscle proteins. To elucidate the molecular interactions among diet, pig genotype, and physiological stage, we examined the effect of dietary protein concentration, pig genotype, and physiological stages on amino acid (AA) pools, protein deposition, and related signaling pathways in different types of s...

Crop landraces are vanishing alarmingly worldwide, posing serious risks to the livelihoods of resource-poor farmers; this study, conducted using ‘vulnerability’ and ‘resilience theory’ frameworks, sought delineate social–ecological, climatic policy hindrances conservation a muskmelon landrace ‘Jaunpuri Netted’ traditionally grown in eastern Uttar Pradesh, India. Our results showed that blue bul...

The objective of this study was to examine the health and meat production of cloned sows and their progenies in order to demonstrate the application of somatic cell cloning to the pig industry. This study compared the growth, reproductive performance, carcass characteristics and meat quality of Landrace cloned sows, F1 progenies and F2 progenies. We measured their body weight, growth rate and f...

Wheat landraces in Turkey are an important genetic resource for wheat improvement. An exhaustive 5-year (2009-2014) effort made by the International Winter Wheat Improvement Programme (IWWIP), a cooperative program between the Ministry of Food, Agriculture and Livestock of Turkey, the International Center for Maize and Wheat Improvement (CIMMYT) and the International Center for Agricultural Res...
