Studies on morphology in backcross generations of interspecific hybrids between Oryza sativa and Oryza officinalis



Studies on morphology in backcross generations of interspecific hybrids between Oryza sativa and Oryza officinalis



Acta Agriculturae Zhejiangensis 9(4): 169-173



F1 hybrids were obtained by crossing the male sterile O. sativa cultivars Zhong 86-44 and Zhong 156 with lines YD1785 and 3-66, respectively, of the distant wild species O. officinalis. Upon backcrossing with the respective female parents, 6 and 7 types of BC1F1 plants, respectively, were obtained by embryo rescue. All were male sterile. Upon further backcrossing to O. sativa and embryo rescue, 4 types of BC2F1 plants were obtained, the majority of which were fertile.
