영문 초록

To introduce the genes of Lead-rice resistant to rice blast and bacterial leaf blight, addition lines were grown and the multilines were to be developed by adding resistant gene from the addition lines. In the F₄ generation of addition lines, disomic lines and 2n=26 plant, the promising 11 resistant lines were used for reciprocal crosses with the commercial varieties. The grains of 1863 were obtained from the 93 crosses made between the females of commercial varieties and males of resistant lines, and 2545 havested from the 51 crosses between the females of resistant lines and males of commercial varieties. The rice blast resistance was examined on the F₁ plants obtained from the reciprocal crosses. Since all the plants tested are resistant the genes controlling resistance must be dominant. In the anther culture 53 green plants were obtained out of 758 callus culture. Screening the chromosome number of the 53 green plants produced from callus, 37 plants of those were found haploids and 9 plants diploids.
