1 Improvements in the production of doubled haploids in durum wheat ( Triticum turgidum L . ) through isolated microspore
The objective of this study was to produce durum wheat doubled haploid plants through the induction of microspore embryogenesis. The microspore culture technique was improved to maximize production of green plants per spike using three commercial cultivars. Studies on factors such as induction media composition, induction media support and the stage and growth of donor plants were carried out i...

haploid plant per floret (Devaux, 1988). Androgenesis induction in microspores may be affected by various An efficient doubled-haploid production technology that induces factors which cause low induction efficiency and by gehomozygosity can greatly reduce the time and cost of cultivar developnotype dependence (Dunwell, 1985). Most advances toment. Low efficiency of doubled-haploid production pr...
متن کاملThe wheat (Triticum aestivum L.) leaf proteome.
The wheat leaf proteome was mapped and partially characterized to function as a comparative template for future wheat research. In total, 404 proteins were visualized, and 277 of these were selected for analysis based on reproducibility and relative quantity. Using a combination of protein and expressed sequence tag database searching, 142 proteins were putatively identified with an identificat...
متن کاملVernalisation Response of Some Winter Wheat Cultivars (Triticum aestivum L.)
For 17 cultivars of winter wheat (Triticum aestivum L.) different vernalisation and photoperiod responses were detected. The effect of photoperiod sensitivity was not significantly changed by vernalisation; different vernalisation responses were probably due to the presence of multiple alleles at Vrn loci. The delay in heading depended on the vernalisation deficit exponentially: y = parameter (...
متن کاملSimulation of Maintenance Respiration in Wheat (Triticum aestivum L.)
Respiration has a profound influence on crop yield because dry matter accumulation by a crop is closely related to assimilation of CO and respiratory activity. This paper describes the development of a 2 simulation model for respiration in wheat. While the growth respiration can be assumed to be proportional to the assimilation of CO , the model concentrated on the effects of biotic and environ...
