The objective of this study was to estimate genetic parameters and to investigate the type of gene action in controlling androgenesis in wheat. Two wheat cultivars of Grebe and Houtman were reciprocally crossed with two synthetic genotypes of Do1 and Pol and then a complete set of the parents, F1, reciprocal F1 (RF1), F2 and back-cross generations (BC1 and BC2) of each cross were used for anthe...

Castor (Ricinus communis L.) is one of the most ancient medicinal oil crops in the world. It has been vastly distributed in different parts of Iran. In the present study, the inter simple sequence repeat (ISSR) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of Iran. Totally, 16 ISSR primers amplified 166 loci...

Genetic study of pistachio, especially male genotypes due to the effects of pollen on nut quality and quantity and next generation characterizations, help to improve its management and breeding programs. We studied the genetic diversity among 20 male and 36 female pistachio genotypes using ISSR marker. In total 178 DNA frgments were proliferated using 12 primers that 169 fragments were polymorp...

the citrus leafminer, phyllocnistis citrella stainton (lepidoptera: gracillariidae) is a major invasive pest of citrus in tunisia. in order to help the implementation of an efficient integrated management strategy, it was essential to assess the genetic diversity and population structure of the pest. for this purpose, random-amplified polymorphic dna-polymerase chain reaction (rapd-pcr) was app...

iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. the amplified fragment length polymorphism (aflp) marker was applied to investigate the genetic variations among five major iranian melon cultigens (cucumis melo) and ‘ananasi’ as a general well-known cultivar. ten primer pairs were used on 90 indiv...

the genetic diversity of 20 iranian populations of bunium persicum has been evaluated with random amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp) markers. fresh leaves of seedlings from each population were used for genomic dna extraction. analysis of banding patterns of 15 rapd primers and 17 aflp primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

genetic diversity is necessary for breeding program and increasing genetic gain of selection in crop plants. with the onset of spring growth, spring cold stress is a problem for wheat crops at heading and also may be damaged some other parts of this plant. the aim of this study is the investigation of genetic diversity duo to artificial cold stress on the physiological traits, chlorophyll a, ch...
