Evaluation of Resistance of Transgenic Rice with Lysozyme Gene Transferring Indica Rice Parents Minghui63 Against Rice Blast

Traditional breeding method and modern genetic engineering technology are combined in order to efficiently obtain new strains of high resistance and create new hybrid rice with fine agronomic characters and strong resistance to rice blast germ.By crossing and continual back crossing,lysozyme gene has been transferred from transgenic rice Zhonghua9 (ZH9(R))—japonica rice to hybrid rice parents Minghui63(MH63)—indica rice.That has been proved by way of filtration of resistance and PCR analysis.The resistance of transferring generations are much better than their indica type rice parent.Disease index of leaf blast and loss percent of spike blast are respectively decreased by 39.39 and 10.21%.Now 167 offspring has been attained.
