Genetic Control of Root Weight, Root Volume and Root to Shoot Weight Ratio in Peas

The genetic control of root weight, root volume and root to shoot weight ratio was studied in peas (Pisum sativum L.) at flowering. The four populations used were developed from crosses between lines and cultivars differing in size of the root systems. Plants of the F1, F2 , back cross and parenta...
