Association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. This study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. This investigation was performed using 77 barley genotypes and AFLP markers. In phenotypic evaluation, reaction of seedlings to powdery mild...

Characterization of saffl ower (Carthamus tinctorius L.) with molecular markers is needed to enhance germplasm management and utilization. Amplifi ed fragment length polymorphism (AFLP) analysis was completed in saffl ower resulting in 102 unambiguous polymorphic markers. Pairwise distances were calculated for eight diverse populations of 12 plants each, and on bulked leaf tissue of 96 accessio...

Canola quality Brassica juncea has been under development at the Saskatoon Research Centre for several years. Breeding efforts have focused on the development of germplasm with improved seed quality characteristics including superior fatty acid profiles, low glucosinolates and high oil content. Future breeding efforts in this crop would be greatly facilitated through the development of molecula...

A natural male sterile mutant of Salvia miltiorrhiza (Labiatae, Sh-B) was found during field survey in 2002. Our objective was to analyze its genetic mechanism for producing F1 hybrid seeds and to develop a molecular marker linked to male sterile gene for selection of a hybrid parent line. The segregation ratios of male sterile plants to fertile plants in the progenies of both testcross and bac...

Random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers were used to assess the genetic diversity in 31 species of mangroves and mangrove associates. Four AFLP primer combinations resulted in the amplification of 840 bands with an average of 210 bands per primer combination and 11 RAPD primers yielded 319 bands with an average of 29 bands per primer. Th...

This study was carried out to compare agro-morphological traits and nutritive value of 25 tall fescue (Festuca arundinacea) ecotypes grown in Tehran, Iran. The experiments were carried out in a split plot design during 2016-2018 growing seasons. The results showed that there was a significant genetic variation in existing germplasm. The highest heritability was related to dry forage yi...

 Flowering period and longevity play important roles in determining the quality of commercial flowers. Marker-trait associations for eight flowering and 12 ornamental traits have been studied using a GLM and MLM analysis with a set of 2099 AFLP polymorphic markers in Chrysanthemum. The GLM model identified 453 markers for phenotypic traits whereas the MLM association analysis model revealed a t...

The amplified fragment length polymorphism (AFLP) method produces anonymous genetic markers from throughout a genome. We extend the nucleotide substitution model of AFLP evolution to additionally include insertion and deletion processes. The new Sub-ID model relaxes the common assumption that markers are independent and homologous. We build a Markov chain Monte Carlo methodology tailored for th...

This article refers to viewing the role of molecular markers during analyzing genome plants and their importance in plant biotechnology. In recent years, we observed techniques programs for improving breeding preserving genetic resources has been observed, biochemical indicators which represent basic material through determining diversity between genotypes it is never affected by external surro...

Amplified fragment length polymorphism (AFLP) markers allow a rapid assessment of the level of genetic variation that would be difficult to evaluate using a limited number of morphological markers. AFLP was used to assess the level of genetic variation among 16 different Phalaenopsis species and hybrids. Ten AFLP primer combinations were used for genetic analysis of these Phalaenopsis and 95% o...
