Cytological Basis and Molecular Mechanism of Variation in Number of Seeds Per Pod in Brassica napus

Abstract

The number of seeds per pod in Brassica napus shows great variation among different cultivars, lines and germplasm resources. Studies on this trait are important in increasing rapeseed yield by utilizing advantageous variations. In this study, we revealed the cytological basis and molecular mechanism of the formation of variation in number of seeds per pod in Brassica napus through analyzing a series of doubled haploid lines and cultivars. The results showed that a part of ovule primordiums could not develop into mature seeds …
