Haploid production technology in wheat and some selected higher plants
Haploid plants are very important in various realms of research disciplines such as plant biotechnology, molecular genetics and traditional plant breeding. They provide useful information regarding recombination and genetic control of chromosomal pairing. Haploidy expedites the breeding process thereby increasing the crop yield. Researchers have been working on the haploidy approach for more th...

15 صفحه اولDevelopment of yellow rust resistant doubled haploid lines of wheat through wheat ´ maize Crosses
In order to produce doubled haploid lines of bread wheat resistant to strip or yellow rust, three F1 wheat hybrids were crossed using pollens of three maize hybrids. Out of 1071 pollinated florets, success in seed set ranged from 63.1% to 93.3% (mean 78%). Differences in seed set among the crosses were not significant. Embryo formation in the seeds developed on different crosses also varied fro...
متن کاملEfficient haploid and doubled haploid production from unfertilized ovule culture of gentians (Gentiana spp.)
Factors affecting reliable plant regeneration from unfertilized ovule culture of gentians (Gentiana spp.) were examined. Cold pretreatment (4°C) of flower buds enhanced or maintained production of embryo-like structure (ELS). When 43 genotypes were surveyed in two different labs, 40 of them produced ELSs ranging from 0.01 to 26.5 ELSs per flower bud. No ELSs could be obtained in three genotypes...
