Understanding the mechanisms of plant salt tolerance as a complex trait is an integral part many studies, results which have been used in breeding process. The aim this study was to compare root response two tomato (Solanum lycopersicum L.) genotypes (breeding line YaLF and cultivar Recordsmen) differing tolerance. Rhizogenesis induced shoots vitro with different concentrations NaCl culture med...

Analysis of rare genetic variants has focused on region-based analysis wherein a subset of the variants within a genomic region is tested for association with a complex trait. Two important practical challenges have emerged. First, it is difficult to choose which test to use. Second, it is unclear which group of variants within a region should be tested. Both depend on the unknown true state of...

Analysis of genetic diversity among genotypes and differentiation populations are crucial for determination conservation strategies one the best plant breeding approaches. In this study, ISSR markers were used to determine variation population structure in 23 hulled wheats. Together with control durum wheat bread registered cultivars, 32 analyzed 14 located throughout genome. Number alleles per...

this study was carried out in order to investigate on chromosomal behavior during meiosis in herbaceum (iranian endemic), arboretum species, f1 hybrids of two species and bc4 genotypes. the endemic varieties used in this study were semnan and shahreza (herbaceum) and vtdl as arboretum cultivar. f1s investigations showed that in the adjacent and alternative quadrivalents frequently but the bc4 o...

Combination breeding and mutation are widely used methods in plant breeding. Intensive studies carried out on biotechnological that will allow obtaining homozygous lines a short time populations obtained with these two techniques. Numerous have been by different researchers wheat. There few anther culture response mutagen-treated genotypes. Two bread wheat promising advanced were as the materia...

the polymorphism in exon three of fabp4 gene and its association with growth traits of 45 sistani (n=30) and dashtiari (n=15) cattle were investigated. dna extraction from the whole blood was performed and its quality was determined by electrophoresis of one percent agarose gel. animal genotypes were determined based on polymerase chain reaction (pcr) products and their band size electrophorese...

Restriction fragment length polymorphisms (RFLP) have been identified at the goat. The objective of the present study was to determine polymorphisms of calpastatin locus in Raini and Tali goats of the goats in Kerman Province, improving meat quality traits superior meat quality by selection. Calpastatin gene effect on quality and tenderness meat, to identify different genotype of this gene was ...

Using 102 pepper (Capsicum annuum) genotypes, a greenhouse experiment has been conducted to study genotypic variation in tolerance to 100 mM sodium chloride (NaCl) in nutrient solution. Based on the severity of leaf symptoms caused by the NaCl treatment there was a substantial genotypic variation in salt tolerance. From this screening experiment, six sensitive and six tolerant genotypes were ch...

Abstract Knowledge of the impacts sex on plant mortality and biomass production has scientific practical importance. In case willows, we know relatively little about such effects. The main objective this study was to evaluate whether individuals different willow species determines their mortality. An additional goal determine secondary characteristics, as leaf traits, depend sex. experiment con...
