Broad-sense heritabilities and genetic correlations of maximal oxygen consumption (VO2max), blood hemoglobin levels, and ventricle mass were estimated in a natural population of snakes. Traits were measured for six or fewer presumed full-sibling offspring from each of 45 wild-caught gravid garter snakes (Thamnophis sirtalis). VO2max was highly reproducible between replicate trial days (r = 0.88...

the russian wheat aphid (rwa), diuraphis noxia (mordvilko), is a significant insect pest of wheat worldwide. the objective of this study was to assess the genetic variation within and between f2-derived families for reaction to rwa using f3 and f4 families originating from individual f2 plants of a cross between the susceptible line (synthetic hexaploid-11) and the resistance cultivar (‘halt’)....

Twelve genotypes of bread wheat, with four levels nitrogen (0, 75, 150, 225 kg N ha-1). were grown in split block design three replication growing season (2021), correlation, phenotypic and genotypic coefficient variation, heritability genetic advance estimated for (days 75% flowering, plant height, grain filling, yield, number spike/plant, spike length, weight, flag leaf area, biomes, protein ...

general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...

The genetic architecture of quantitative characters in plants can be influenced by stress due to environmental changes, combination with the decrease organism’s average performance, resulting and variances. main objective this study was determine how high-temperature affects sensitivity three populations soybean foliar blight pathogen Rhizoctonia solani AG-1 IA from Mato Grosso, Maranhão, Tocan...

This study included four genotypes of cucumber (IC257296, IC420405, GYNE-5, PUSA SANYOG) which were evaluated based on phenotypic traits when grown under two different soil zones Doha (Qatar) and Meerut (India). Statistical analysis to estimate various genetic parameters like genotypic variance, coefficient variation (PCV GCV), broad sense heritability gain principal component (PCA) was done in...

Sorghum is the second most important food crop after teff in Ethiopia. The objective of study was to estimate genetic variations, heritability, and expected advances selected sorghum genotypes. Sixty-four genotypes were evaluated for 17 quantitative traits 8x8 simple lattice designs at Boko research site. analysis variance revealed highly significant differences among all traits. Phenotypic Coe...

For most complex traits, results from genome-wide association studies show that the proportion of the phenotypic variance attributable to the additive effects of individual SNPs, that is, the heritability explained by the SNPs, is substantially less than the estimate of heritability obtained by standard methods using correlations between relatives. This difference has been called the "missing h...
