Thirty mango genotypes were studied to find out their variability, heritability, and genetic advance. Significant variations observed in 46 characters. There also considerable differences between the genotypic phenotypic coefficients of variation for almost all characters which indicated influence environment on expression these traits. Among characters, GCV PCV high 40 All showed considerably ...

Resistance breeding is the most effective method to control northern corn leaf blight (NCLB). The objectives were (1) Assess effects of dominant genes (Ht(s)), polygene (PG), and their combinations disease rating (DR), number lesions per (NLPL), lesion size (LS); (2) Estimate genetic components, general combining abilities (GCA), heritability under two Line × Tester analyses; (3) Determine gene...

The experiment was conducted with 60 hybrids developed by crossing two male sterile lines 30 diverse testers studied for gene action and heterosis. ANOVA combining abilities  revealed that the parents are significantly different all traits under study. ratio of gca:sca variance found less than unity indicating presence non-additive average degree dominance greater indicated predominance ov...

In the present study, a set of six female (lines) and seven restorers (testers) pearl millet were crossed in Line × Tester mating fashion. The newly synthesized hybrids evaluated for yield performance during Summer, 2020. high magnitude SCA variance indicates predominance non-additive gene action all characters. Hence, heterosis breeding method is suggested to exploit this kind action. estimate...

Six lines and five testers were crossed in line x tester fashion and the F1s were evaluated under coastal saline situation. The ratio between the estimates of additive and dominance variances indicated preponderance of nonadditive gene action for the characters namely, plant height, number of productive tillers, boot leaf length, panicle length, grain weight per primary panicle and grain yield ...

An emerging infectious pathogen Hymenoscyphus pseudoalbidus has spread across much of Europe within recent years causing devastating damage on European common ash trees (Fraxinus excelsior) and associated plant communities. The present study demonstrates the presence of additive genetic variation in susceptibility of natural F. excelsior populations to the new invasive disease. We observe high ...

Cotton germplasm was analyzed to investigate its potential for developing water stress tolerance in varieties in the future. Four tolerant (NIAB-78, CIM-482, BH-121, and VH-142) and four susceptible (CIM-446, FH-1000, FH-900, and FH-901) lines were identified of 50 accessions based on their seedling root length. A complete set of diallel crosses among eight selected genotypes was subjected to g...

In order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five CMS lines and four restorer lines (tester) were crossed in a line × tester scheme. Hybrids were evaluated in a randomized complete block design with three replications in the Agriculture Research Station, University of Tabriz, in 2009 and 2010 growing seasons. Plant height,...

The problem of nonlinear filtering with a non-Gaussian model of measurement errors is considered in this paper: Based on Bayes classification of the observations an approximate solution is introduced. The Bayesian estimator can be applied to any discrete time, lineal; or nonlinear system which is observed in additive non-Gaussian measurement noise. The problem of narrowband inte$erence suppress...

Introduction: Development of higher energy modalities such as positron emission tomography/computed tomography (PET/CT), has led to more complex shielding problems. This is due to several factors, such as the radiopharmaceutical relatively high-administered activity, high patient throughput, and high energies of 511 kilo-electron volt (keV) positron annihilation photon...
