Breeding value of dihaploid lines of spring rapeseed (Brassica napus L.)

In modern genetic researches and breeding of cruciferous oilseed crops, biotechnological methods are widely used to develop clean lines - doubled haploids through anther culture and isolated microspores in vitro. Unlike with the traditional breeding methods, using the haploidy method one can get completely homozygous plants within one year, which can significantly accelerate the breeding process. The studies were conducted at the fields of V.S. Pustovoit AllRussian Research Institute of Oil Crops. The aim of this work was to evaluate the dihaploid lines of spring rapeseed (Brassica napus L.) by a set of economic traits suitable for breeding of varieties and hybrids. We estimated economic value of dihaploid lines of spring rapeseed. These lines were developed by a method of anther culture and isolated microspores basing on intraspecific hybrids F1 From the 200 dihaploid lines after estimation in field, we selected nine lines promising by a complex of economic traits...
