Abstract: To breed rapeseed resources of dwarf and compact type, the microspore culture of filial generation F1 from cross of‘3H004’(female parent) and‘7399-8’(male parent) was carried out and DH separation group was obtained. Phenotypic characteristics of the DH separation group were authenticated by plant height, branch characteristics, length of main inflorescence, the total number of pod, growth period and the oil content in many sites and many years, rapeseed resource‘DH09-3048’was bred, which had natural caps and limited pods of main inflorescence, short flowering phase, focused pod layer, dwarf and compact type of plant. In the test of hybrid combinations, the combinations matched by‘DH09-3048’showed the characteristics of high yield, compact type and lodging resistance and suitable for mechanized harvesting, which had strong application potential.
