“锡御糯”选自“苏御糯”的矮秆变异株,经5年分离筛选于1989年育成,其株高较“苏御糯”矮30cm;叶片挺立、短、厚而色深,抗倒性强,增穗增粒、抗稻瘟病,增产40％左右。为探明“锡御糯”在水稻育种亲本应用上的特殊价值,故配组粳稻品种与“锡御糯”杂交试验。1 材料与方法1.1材料 以“锡御糯”为父本,“武育粳2号”及“93-25”为母本进行杂交。1.2方法 母本进行化杀去雄,自然授粉;小区为5行区。单株系统选择法;F_2代在抽穗结束后测定每
“Sikuanguo” was selected from “Suyu Nuo” dwarf mutant. After 5 years of isolation and screening, it was bred in 1989 and its plant height was 30cm shorter than that of Suyu Nuo. The leaves were erect, short, thick and dark in color, Strong resistance to lodging, by spike granulation, blast resistance, an increase of about 40%. In order to find out the special value of “Xi Yu Nuo” in the application of rice breeding parents, we crossed the hybrid rice experiment with japonica rice varieties and “Xi Yu Nuo”. 1 Materials and methods 1.1 Materials “Tin Yoo waxy” as the father, “Wuyujing 2” and “93-25” as the female hybrid. 1.2 method to kill the male parent to kill, natural pollination; district for the 5 line area. Single-plant selection method; F_2 generation was measured at the end of heading
