Chemical and morphological characteristics of common bean seed and evaluating genetic advance in commercial classes.

Common bean (Phaseolus vulagris L.) is a nutritionally important food crop with prospective health benefits in the world. The current study was evaluated the chemical components, morphological characteristics, and genetic advance of 22 common bean cultivars/lines seeds from three commercial classes (white, red, pinto beans) adapted to different climates of Iran.

Genomic Regions From an Iranian Landrace Increase Kernel Size in Durum Wheat.

Kernel size and shape are important parameters determining the wheat profitability, being main determinants of yield and its technological quality. In this study, a segregating population of 118 recombinant inbred lines, derived from a cross between the Iranian durum landrace accession "Iran_249" and the Iranian durum cultivar "Zardak", was used to investigate durum wheat kernel morphology factors and their relationships with kernel weight, and to map the corresponding QTLs. A high density genetic map, based on wheat 90k iSelect Infinium SNP assay, comprising 6,195 markers, was developed and used to perform the QTL analysis for kernel length and width, traits related to kernel shape and weight, and heading date, using phenotypic data from three environments.

Morphological and molecular genetic variations of oat genotypes grown in Kermanshah, Iran.

Morphological traits and molecular markers are two common methods for genetic variation studies. Molecular markers, morphological traits methods and relationship between the two were used to study genetic variation among 43 oat genotypes and varieties. For this purpose, an augmented design was conducted in three replicates at 2008-2009 cropping season in the experimental field of Campus of Agriculture and Natural Resources of Razi University, Kermanshah, Iran.

Effects of magnetic field on cell dedifferentiation and callus induction derived from embryo culture in bread wheat (Triticum aestivum. L) genotypes.

Current study was conducted to investigation of effect of magnetic field on cell dedifferentiation and follow it callus induction derived from mature embryo culture in bread wheat genotypes. For this purpose, a factorial experiment based on completely randomized design was carried out with two wheat genotypes and three level of magnetic field strength (0.0, 8.

Identification of RAPD markers and their use for molecular mapping in pea (Pisum sativum L.).

The RAPD method (Random Amplified Polymorphic DNA) was used for identifying and mapping new molecular markers in pea. RAPD analysis of various cultivars and lines of pea was carried out using 10-mer random primers. The presence of multiple polymorphism between cultivars and lines was revealed; at least one fragment for any given primer was present in the DNA of one form of pea and absent in the DNA of another line or cultivar.
