We examined the effect of incorporation of molecular markers on variability between and within populations in order to maximize heterotic effects and longevity of a maize reciprocal recurrent selection program. Molecular variability was quantified by inter-simple sequence repeat (ISSR) markers between and within the maize populations Cimmyt and Piranão in the 10th cycle of a reciprocal ... more

ISSR; Molecular marker; RAPD

Dalbergia oliveri is a leguminous tree of the Fabaceae family. This species is popular and valuable in Vietnam and is currently listed on the Vietnam Red List and on the IUCN Red List as endangered. Two PCR techniques using RAPD and inter-simple sequence repeat (ISSR) markers were used to make a comparative analysis of genetic diversity in this species. Fifty-six polymorphic primers (29 ... more

We evaluated the efficiency of the touchdown method to determine the ideal PCR conditions for distinct inter-simple sequence repeat primers for processing DNA from common corn, popcorn, sweet corn, and a Tripsacum-maize hybrid. Genomic DNA was extracted from eight accessions of corn: two of the dent type, one Tripsacum-maize hybrid, one sweet corn, one flint-type corn, ... more

Genetic variability; ISSR; Mandacaru; morphology; RAPD

This is the first study to examine the genetic diversity of mandacaru cactus (Cereus jamacaru P. DC.). Plants of spineless mandacaru are commonly found in gardens and parks of urban areas in northeastern Brazil. In addition to exploring their ornamental potential, morphological, and genetic characterization may contribute to the development of plant materials that can be used as ... more

Fusarium verticillioides; Intron; ISSR; RAPD

Fusarium verticillioides is a pathogen of agriculturally im­portant crops, especially maize. It is considered one of the most impor­tant pathogens responsible for fumonisin contamination of food products, which causes severe, chronic, and acute intoxication in humans and ani­mals. Moreover, it is recognized as a cause of localized infections in im­munocompetent patients and ... more

Interspecific hybrids; ISSR; Morphological trait; RAPD; Solanum melongena; Solanum torvum

Interspecific hybrids between cultivars of eggplant (Solanum melongena L.) and its wild relative S. torvum, which has disease resistance and desirable traits for crop improvement, were obtained by cross-hybridization and embryo rescue. Twenty-one hybrid progenies were obtained and examined based on morphological traits, RAPD and ISSR markers. Five of them were confirmed ... more

Agronomic traits; Genetic variation; Gossypium hirsutum L.; ISSR; RAPD; SSR

Cotton is one of the most economically important crops in Iran; hybridization is a means to increase the genetic diversity and obtain new elite cultivars in this crop. We examined agronomic characteristics and molecular genetic diversity in the Opal cotton (Gossypium hirsutum) cultivar and in F2 progenies. Ten homo-primers and seven hetero-primers of 26 RAPD primers ... more

Achillea species; Genetic diversity; ISSR; Marker; RAPD

Cultivation and preservation of yarrow has recently attracted wide attention due to its beneficial properties; however, genetic variation of Achillea species is still relatively unknown. We used RAPD and ISSR markers to assess genetic diversity in 16 accessions of yarrow belonging to two species native to Iran. Seven ISSR and nine RAPD primers generated 187 amplified fragments, ... more

ISSR; RAPD; Sequence characterized amplification region; Thinopyrum elongatum

Diploid Thinopyrum elongatum, a wild relative of wheat, contains many agronomically desirable traits and has potential for increasing genetic variability and introducing desirable characters in this crop. Few molecular markers are available for rapid screening of T. elongatum genome segments in the wheat genetic background. We used 36 RAPD primers and 33 ISSR primers to ... more

conservation genetics; Fishes; ISSR; Molecular markers; Morphometric analyses

Molecular genetic assessments that consider ecological information, in addition to endogamy levels, genetic diversity, and the genetic differentiation among species and populations, are particularly important for the conservation of biological diversity. Prime candidates for conservation genetic review are those subject to human use, including harvests for the ornamental fish trade. ... more
