Using native trees from near the northern and southern extremities of the relatively continuous eastern distribution of Eucalyptus globulus in Tasmania, we compared the progenies derived from natural open-pollination (OP) with those generated from within-region and long-distance outcrossing. Controlled outcrossing amongst eight parents - with four parents from each of the northern and southern ...

incompatibility in hazelnut (c. avellana l.) is the sporophytic type and under the control of a single s-locus with multiple alleles. compatibility of pollen-stigma in hazelnut is an important consideration in planning crosses in breeding program and in choosing pollinizers for orchard planting. in this study, fluorescence microscopy was used to determination of s-alleles and compatibility rela...

salinity is one of the abiotic stresses and exploitation of heterosis could increase the crop yield and extend the stress tolerance, especially in salinity stress. in this research, a set of full diallel design involving 7×7 crosses from cultivars including flat, bam, ghods, roshan, arg, kavir and pishtaz were conducted in a randomized complete block design with three replications under both no...

To assess differentiation and relationships between Anopheles lesteri and Anopheles paraliae we established three and five iso-female lines of An. lesteri from Korea and An. paraliae from Thailand, respectively. These isolines were used to investigate the genetic relationships between the two taxa by crossing experiments and by comparing DNA sequences of ribosomal DNA second internal transcribe...

prediction of superior crosses before their being performed, and an evaluation of the progeny in the field can lead to an increase in the efficiency of hybrid-seed production. a significant number of studies, during recent decades, have proved a positive relationship between heterosis and the genetic distance evaluated through molecular markers. ssr markers were employed to study the relationsh...
