Generation and characterization of Brassica rapa ssp. pekinensis - B. oleracea var. capitata monosomic and disomic alien addition lines.

Five monosomic alien addition lines (MAALs) of Brassica rapa ssp. pekinensis - B. oleracea var.

Generation and identification of Brassica alboglabra-Brassica campestris monosomic alien addition lines.

Four monosomic alien addition lines (MAALs) for Brassica alboglabra-Brassica campestris were developed through digenomic triploid (ACC) backcrossing with the recurrent parent B. alboglabra (CC). The objectives of this study were to compare morphological traits, microsatellite markers (simple sequence repeats), chromosomal karyotypes, and meiotic behaviors.

Determination of n+1 gamete transmission rate of trisomics and location of gene controlling 2n gamete formation in Chinese cabbage (Brassica rapa).

A set of trisomics of Chinese cabbage was used for determining the n+1 gamete transmission rate and locating the gene controlling 2n gamete formation on the corresponding chromosome. The results showed that the transmission rates of extra chromosomes in different trisomics varied from 0% to 15.38% by male gametes and from 0% to 17.
