Genome wide selection and new methods of maize breeding The objectives of this work were to verify the accuracy of the Genome Wide Selection method (GWS) in the maize breeding for nutritional stress conditions and propose new breeding methods based on GWS. The efficiency of two components of use of nitrogen and phosphorus (absorption and utilization) was estimated in 41 single-cross hybrids ass...

Genomic selection is a promising development in agriculture, aiming improved production by exploiting molecular genetic markers to design novel breeding programs and to develop new markers-based models for genetic evaluation. It opens opportunities for research, as novel algorithms and lab methodologies are developed. Genomic selection can be applied in many breeds and species. Further research...

Multiple-objective programming was used to examine the effects various objectives had on the optimal portfolio of sires chosen for a given breeding problem in a Jersey cow dairy herd. It was assumed that the dairy producer had the following three objectives in the breeding decision: to maximize Net Merit, to minimize inbreeding, and to minimize total expenditure on semen. Integer programming mo...

Because most regions of Japan are in the temperate climate zone, many deciduous and evergreen fruit crops are cultivated in Japan. In addition to fruit cultivation in the temperate zone, some southern areas, such as the Ryukyu Islands that stretch from Kyushu to Taiwan, are at the northern limits for tropical fruit production without the need of artificial heating. At present, annual fruit prod...

The objective of this study is to know the system and practice breeding caprine in Abéché city. was undertaken by investigation town for two months (June July 2021), near 50 households. collected data carried on characteristics households (sex, matrimonial situation level surveyed), principal activities surveyed, mode acquisition objectives breeding, systems techniques breeding. results show th...

Background Eucalyptus globulus is a widely planted species in temperate regions of the world for pulpwood production. Its good characteristics for kraft pulping in addition to a broad adaptability to different site conditions have led this species to be employed in commercial plantations and to be included in breeding programs [1]. Uruguay has approximately 300.000 hectares forested with E. glo...

2 0 Prediction of single-cross hybrid performance has been a major goal of plant breeders since the 2 1 beginning of hybrid breeding. Genomic prediction has shown to be a promising approach, but 2 2 only limited studies have examined the accuracy of predicting single cross performance. Most of 2 3 the studies rather focused on predicting top cross performance using single tester to determine 2 ...
