Genetic differences between 20 Chinese wheat (Triticum aestivum L.) landraces highly resistant to Fusarium head blight (FHB) and 4 wheat lines highly susceptible to FHB were evaluated by means of microsatellite markers, in order to select suitable parents for gene mapping studies. Thirty-nine out of 40 microsatellite markers (97.5%) were polymorphic among the 24 wheat genotypes. A total of 276 ...

Understanding the genetic variation in germplasm is of utmost importance for crop improvement. Therefore, efforts were made to analyse the molecular marker based genetic diversity of 20 Annona genotypes from five different species of family Annonaceae. During analysis, a set of 11 RAPD primers yielded a total of 152 bands with 80.01 % polymorphism and PIC for RAPD ranged from 0.86 to 0.92 with ...

The genus Theobroma comprises several trees species native to the Amazon. Theobroma cacao L. plays a key economic role mainly in the chocolate industry. Both cultivated and wild forms are described within the genus. Variations in genome size and chromosome number have been used for prediction purposes including the frequency of interspecific hybridization or inference about evolutionary relatio...

Pomegranate (Punica granatum L.) is one of the most important fruit crop cultivated in Morocco. However, little data is available on its genetic diversity. The genetic relationships among pomegranate cultivars were investigated using Amplified Fragment Length Polymorphism (AFLP) markers. Six pairs of primers were used to analyse 24 pomegranate cultivars obtained from the central regions of Moro...

Heterozygosity is the major constraint in perennial fruit crop like mango for regular bearing breeding. Majority of popular varieties have irregular habit. Many external and internal factors affect habit crops. Among factors, level carbohydrate reserves phytohormones plays a role on crops apple, citrus, mango, litchi etc., Therefore, present research work aimed to study metabolism pathways geno...

Cow milk is a rich source of protein and selected micronutrients such as calcium. Recently, a relationship between disease risk and consumption of a specific bovine β-casein fraction either A1 or A2 genetic variants has been identified. Polymorphism at codon 67 of the beta-casein gene: CCT→CAT causes a substitution of amino acid proline (in A2 variant) by histidine (in A1 variant). The presence...

Abstract Background The preferred choice for molecular marker development is identifying existing variation in populations through DNA sequencing. With the genome resources currently available bitter gourd ( Momordica charantia ), it now possible to detect genome-wide insertion-deletion (InDel) polymorphisms among populations, which guides efficient of InDel markers. Results Here, using bioinfo...

A study was aimed to evaluate a set of polymorphic microsatellite markers for their efficiency in testing parentage Jersey crossbred cattle available Tamil Nadu. The objective validation based on the criteria such as polymorphism information content, various genetic diversity parameters and ability exclude wrong parent. total 21 were included verify 24 trios (comprising dams, progenies 2 sires)...

BURÓCZIOVÁ, M., ŘÍHA, J., ŽIDEK, R., TRANDŽÍK, J., JAKABOVÁ, D.: Genetic structure of nine horse populations. Acta univ. agric. et silvic. Mendel. Brun., 2008, LVI, No. 2, pp. 57–60 In the present study was estimate the genetic diversity and relationships among nine horses breeds in Czech and Slovak Republic. In conclusion, the main objective of study was to show the level of genetic distance a...

Estimation of the heritability for a given phenotype would provide basic information potential breeding programs. As one most precious common carp strains, Yellow River was subject to selection fast growth and slender body meet market demands. In present study, heritabilities shape (body length, BL height, BH) weight (BW) were estimated based on molecular parentage assignment 750 progenies from...
