영문 초록

The present study was focused on variability of anther-derived plants in quantitative characters to obtain basic information for rice breeding through anther culture. Variability of progeny of anther-derived plants, A₂ Lines, were compared with F₂ generation of the same combination. The salient findings obtained are summarized as follows; The segregation and recombination of major characters such as days to heading, panicle length, and panicles per plant both 175 anther-derived A₂ lines and 594 F₂ plants derived from Milyang 74/Dashukei 2 F₁ hybrids presented normal distribution curves and refered to the inheritance of quantitative characters controlled by multiple genes. Expression of gene recombinants related to culm length of 48 anther-derived A₂ lines from singwangbyeo/Eunhatyeo F₁ hybrids showed similar to those of 406 F₂ plants, although average culm length of A₂ population was shorter than that of F₂ population. The segregation and recombination of fertility of 71 anther-derived A₂ lines from Milyang 62/Akibare F₁ hybids as remote cross showed clearly different from those of 578 F₂ plants. The curve of A₂ population appeared more centered, and tilted to higher fertility. This tendency was also appeared both anther-derived A₂ lines and F₂ population derived from Singwangbyeo/Eunhabyeo F₁ hybrids.
