Under the traditional mutation load model based on multiplicative fitness effects, the load in a population is 1-e-U , where U is the genomic deleterious mutation rate. Because this load becomes high under large U, synergistic epistasis has been proposed as one possible means of reducing the load. However, experiments on model organisms attempting to detect synergistic epistasis have often focu...

Six diverse homozygous parents, BWR-1, BWR-6-1, BWR-29, BWR-39, EC-464107 and EC-464115 were evaluated for gene action, heritability combining ability using 6X6 diallel cross excluding reciprocals. The results showed that analysis of variance revealed significant differences due to crosses parent’s vs crosses. Mean squares GCA SCA all traits days 50% flowering, first picking, plant height, prim...

Increasing drought incidence and infertile soils require the improvement of maize for nitrogen use efficiency (NUE) under conditions. The objectives were to assess tolerance genetic effects Algerian populations no-nitrogen water stress. We evaluated a diallel among six vs. 120 kg/ha N fertilization control. Variability was significant their crosses NUE drought. Additive could be capitalized usi...

We examined whether single-nucleotide polymorphisms (SNPs) in the calpain (CAPN) and calpastatin (CAST) genes, described from Bos primigenius taurus, are polymorphic in Nellore cattle. We also looked for a possible association of linkage disequilibrium of this polymorphism with tenderness of the longissimus dorsi muscle after 7, 14 and 21 days of postmortem aging in 638 purebred Nellore bulls. ...

Analysis of generation mean was carried out in six crosses of rice viz., ADT 41 / ADT 46, ADT 41 / CO 47, ADT 41 /TKM 9, ADT 41/ Jeeragasamba, ADT 41/ACM 98003 and ADT 41/AS 90033 for hulling percentage, milling percentage, head rice recovery, kernel length, kernel breadth, kernel L/B ratio, kernel length after cooking, linear elongation ratio and alkali spreading value. The scaling test showed...

Due to the presence of polyphenols and phthalides in Kelussia odoratissima Mozzaf (Umbelliferae; K. odoratissima hereafter), this medicinal plant might be a robust in-feed additive to modulate lipid peroxidation in meat-type chickens. The present study evaluates antioxidative, antihyperlipidemic, and growth-promoting effects of K. odoratissima in meat-type chickens. In a 37-day trial (5-42 days...
