Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high level of fertility. In the present paper, 29 populations of microspore-derived plantlets from cabbage (Brassica oleracea var. capitata) and brocc...

Abstract Background Flowering is an important inflection point in the transformation from vegetative to reproductive growth, and premature bolting severely decreases crop yield quality. Results In this study, a stable early-bolting mutant, ebm3 , was identified ethyl methanesulfonate (EMS)-mutagenized population of Chinese cabbage doubled haploid (DH) line ‘FT’. Compared with ‘FT’, showed early...

Wheat (Triticum aestivum L.) is a major cereal food crop in the world. End-use quality improvement objective wheat breeding programs. ‘Tiger’ hard white winter cultivar with excellent bread baking qualities. The of this study was to identify genetic loci underlying traits Tiger. A doubled-haploid (DH) population derived from cross between Tiger and ‘Danby’ grown two environments. total 17 toget...

Little is known about the genetics controlling the rate of embryonic development in salmonids, despite the fact that this trait plays an important role in the life history of wild and cultured stocks. We investigated the genetics of embryonic development rate by performing an analysis of quantitative trait loci (QTL) on two families of androgenetically derived doubled haploid rainbow trout prod...

Curly kale (Brassica oleracea L. convar. acephala var. sabellica), the most common type of edible kale, characterized by providing rich nutrition and health care functions, is sought after has been listed as top healthiest vegetables in recent trends, aroused interest breeders cultivating new varieties. However, it usually takes more than six years to obtain a homozygous inbred line for commerc...
