متن کاملEfficient Doubled Haploid Production in Brassica napus via Microspore Colchicine Treatment in vitro and Ploidy Determination by Flow Cytometry
An efficient microspore culture protocol was used to rapidly produce homozygous doubled haploid (DH) progeny of crosses between low erucic canola and high erucic resynthesized rapeseed (Brassica napus L.). Microspores of Canadian cultivars ‘Excel’ and ‘Profit’ as well as three F1 hybrids with the resynthetic line RS239 were treated with colchicine immediately after isolation. Flow cytometry was...

this study involves in vitro androgenesis of zea maysl. via anther culture. combination of two embryoinduction media (imss & ypm) in presence of different colchicine concentrations (0, 100, 200, 250, 300and 400 mg/l ) in the pretreatment medium (iml) andpretreatment duration (0, 3, 6 and 9 days) in twogenotypes (dh5×dh7 and eth-m82) were tested.after colchicine pretreatment, anthers were tr...
متن کاملDoubled Haploidy Research for Saskatchewan Crops
Doubled haploidy methodology is commonly used in many agronomically important crops to speed the development of new cultivars. There are a number of advantages in using haploidy technology in both practical application (varietal development, mutagenesis, transformation) and basic research (genomics, biochemical, and physiological studies). Haploid plants are commonly produced using one of four ...
