| Abstract: | A mulberry variety, Morus alba 'Shidareguwa', has a weeping habit and is used as an ornamental and landscape plant. This variety is known for being difficult to propagate by hardwood cuttings. To clarify the mode of inheritance of the weeping character and its relationship to the difficulty in cutting propagation, we crossed 'Shidareguwa' with a non-weeping variety 'Noi' that has a very high rooting ability. The phenotypic segregations exhibited by the F1 and F2 plants suggested that the weeping habit is controlled by a single recessive gene. In tests of the F2 plants for cutting propagation, no obvious correlation was recognized between the weeping trait and the rooting ability of cuttings. As a result, we were able to develop new weeping mulberry strains with improved high rooting ability. |
