영문 초록

Spontaneously doubled-haploid plants (A₀) were recovered from anther culture of japonica rice cultivar “Hwayeongbyeo” which developed by anther culture techniques. Culm length, panicle length, and 1,000-grain weight were compared with those of the donor plants for the determination of variability in A₁ and A₂ generation. Sixty-three percent of 52 A₁ lines were similar to the donor plants, while 21.1% were putative homozygous mutants that had no segregation within the lines and 15.4% showed heterozygous variants in one or more characters. One hundred and fifty seven A₂ lines derived from 33 A₁ lines which were simmilar to the donor plants in A₁ generation showed no significant difference in culm length, panicle length, heading date, and 1,000-grain weight. However, 114 descendents (A₂) of 19 lines varied in A₁ generation showed higher coefficient of variation than those of the donor cultivar “Hwayeongbyeo” in investigated characters, espacially in 1,000-grain weight.
