Reasearch on creating new germplasm of high oil content in B. napus

摘要

Microspore culture of four (F1) hybrid lines of B.napus was made and 1003 DH plantlets were obtained. By selection of 2 successive years for oil content, 16 new accessions were obtained whose oil content varied from 45% to 50.5% with adequate traits, days to flowering and maturing. This result suggested that microspore culture or doubled-haploid breeding would play an important role in creating new germplasm of B. napus, especially in polygenic traits such as oil content.
