Image analysis measurements and repeatability estimates of siliqua morphological traits in Brassica campestris L

Euphytica Aims and scope Submit manuscript


The repeatabilities of six traits; peduncle, pod, beak, and total siliqua length, seed number/siliqua and seed mass/siliqua were estimated for the random-mating CrGC-1 Brassica campestris L. population. All length measurements were made using a fast digital image analysis technique. Beak, pod, and total siliqua length showed the highest repeatabilities of all six traits (0.73, 0.63, and 0.63, respectively). Both pod and total siliqua length were highly correlated with both seed number and seed mass/siliqua. These results suggest that these siliqua-related morphological traits could be used as indirect indices of selection in breeding for improved seed yields in Brassica campestris L.
