摘要

本研究爲了初步檢討水稻花藥培養所育成雙單元體植株之育種價值，乃選用遺傳質純接台稻株之花藥所誘得雙單元體品系進行本試驗。結果發現：從花藥之培養到雙單元體植株之誘導的整個過程中，產量4要素之有關遺傳因子極可能發生各類不易查覺之突變，且突變後之遺傳因子對本省一、二期作生育環境之適應能力也有若干程度之差異。文中曾就此等結果加以討論，並據此等結果推論水稻之花藥培養應有利於雜接合育種集團遺傳多樣性之擴大，而實際俾益於新品種之選育。

並列摘要

The present studies were conducted to evaluate the value of doubled-haploid plants in rice breeding. Four of 100 completely homozygous lines developed through anther culture were randomly selected for field trial. The results of statistical analysis showed that the micromutation of quantitative characters had been induced during the process of doubled haploid development following anther culture. The performance of four major yield components controlled by minor genes as well as mutated genes, differed from crop seasons due to different climatic conditions. The advantages of using hybrid anther for tissue culture to increase the genetic variability of doubled-haploid plants so that to increase the chance of selection had been stressed.
