Acidity is one of the main determinants taste and quality melon fruit, together with sugars volatilecompounds. The aim this study was to investigate inheritance hydrogen potential (pH) titratable acidity in fruit.A randomized block design three replications used evaluate F1and F2generations backcrosses (RC1and RC2) ofthe Védrantais (Cucumis melo subsp. var. reticulatus) high pH low acidity, AC-...

The estimates of general combining ability effects suggested that among females GDM-4 and males IC-399819 EC-766060 were the best combiners for seed yield few other characters. specific revealed hybrids GM-2 x EC-766437 followed by RH-406 EC-766378 exhibited positive sca in desirable direction per plant. hybrid EC-766043 RH-749 EC-766495 significant negative days to 50 cent flowering GM-3 matur...

partial diallel design can be used to investigate the general and specific combining ability, and heterosis. combining ability and heterosis were studied in a 6×6 partial diallel cross to see the nature of gene action for fruit quality indices in cucumber (cucumis sativus l.) during 2007 to 2009. analysis of variance revealed highly significant differences among all the f1 hybrid means and thei...

genetic parameters for birth weight (bw), weaning weight (ww), 6 months weight (6mw), 9 months weight (9mw) and yearling weight (yw) in baluchi sheep were estimated using data collected during a 26-year period (1984-2010). estimates of (co)variance components were obtained by reml procedures by fitting a linear mixed animal model. significant random effects for each trait were explored by fitti...

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...

Eight quantitative traits of an F2 MAGIC population in rice were subjected to analyze variability, correlation and path analysis. The results third fourth degree statistics (skewness kurtosis) showed that Individual dried straw weight, 1000-seed grain yield, Number effective tillers are associated with complementary gene interaction, requiring intense selection, while Plant height, Panicle leng...

Regulation of transcription can be a complex process in which many cis- and trans-interactions determine the final pattern of expression. Among these interactions are trans-interactions mediated by the pairing of homologous chromosomes. These trans-effects are wide ranging, affecting gene regulation in many species and creating complex possibilities in gene regulation. Here we describe a novel ...

We show how the phenomena of genetic dominance, overdominance, additivity, and epistasis are generic features of simple diploid gene regulatory networks. These regulatory network models are together sufficiently complex to catch most of the suggested molecular mechanisms responsible for generating dominant mutations. These include reduced gene dosage, expression or protein activity (haploinsuff...

Human memory is a highly heritable polygenic trait with complex inheritance patterns. To study the genetics of memory and memory-related diseases, hippocampal functioning has served as an intermediate phenotype. The importance of investigating gene-gene effects on complex phenotypes has been emphasized, but most imaging studies still focus on single polymorphisms. APOE ε4 and BDNF Met, two of t...
