Gametoclonal changes are an additional source of genetic variation suitable for use in crop improvement programs a range agronomic traits. The aim the study was to accelerate development genetically stable DH rice lines with high morphological and uniformity by method experimental haploidy vitro based on breeding valuable samples specified characteristics carrying genes wide spectrum blast resi...

poplar trees are appropriate species for plantation and forest rehabilitation because of fast growing and high wood yield, as well as adaptability to unfavorable climate. salinization of soil and high temperature are the inhibitory factors in khuzestan province. populus euphratica is a tree species that tolerates soil salinity and high temperature. acclimatization of cut seedling of three popul...

Plant tissue culture comprises a set of in vitro techniques, methods and strategies that are part of the group of technologies called plant biotechnology. Tissue culture has been exploited to create genetic variability from which crop plants can be improved, to improve the state of health of the planted material and to increase the number of desirable germplasms available to the plant breeder. ...

Putative gamete-derived progenies from two Hylocereus species, the diploid H. monacanthus and the tetraploid H. megalanthus, were studied with the dual aims to confirm their gamete origin and to evaluate their potential use as genetic resources. An additional goal was to determine the origin (allotetraploid vs. autotetraploid) of H. megalanthus by exploring morphological variations in the di-ha...

Head cabbage androgenic genotypes of R1 and R2 generations derived from Jaguar F1 donor hybrid were evaluated according to their agroeconomical characters, ability for generative propagation, self-incompatibility, intraline uniformity and stability of morphological characters. Most of R1 and R2 genotypes had desired morphological characters. However, in R1 generation 21 lines showed lack of int...
