Doubled haploids of carnation (Dianthus caryophyllus L.) were obtained by pseudofertilized ovule culture. Emasculated ̄ower buds of carnation were pollinated with pollen inactivated by Xray irradiation. After 2±3 weeks, the ovaries were explanted and were cultured on solid MS medium containing 2 mM NAA, 2 mM BAP and 6% sucrose. Regenerated plants(R0) were morphologically different from the moth...

Lodging affects grain quality and yield in wheat (Triticum aestivum L.) is difficult to breed for because its sporadic incidence laborious protocols measure lodging traits. Thus, developing molecular markers these traits can increase selection efficiency breeding programs. The aim of this article identify quantitative trait loci (QTL) associated with stem/anchorage strength leverage (lodging tr...

Abstract Background Artificial synthesis of octoploid rapeseed double haploid (DH) induction lines Y3380 and Y3560 was made possible by interspecific hybridization genome doubling techniques. Production pure DH provides a new way to achieve homozygosity earlier in B.napus . Previously, the mechanism induction, whether has obvious maternal genotypic differences or not, are not known so far. Resu...
