  1. Abstract : the main characters and seed set of bc1 ， bc2 ， bc1f2 from ms line back - crossing with the pollen of hybrid rice were studied. the appearance of a large number of self fertile plants in ms line was analyzed. the effect of introgression of restoring genes on ms line purity and hybrid yield in indica and japonica rice was discussed. it was pointed out that “ iso - cytoplasm restorer line ” was seriously reducing the purity of ms line and that hybrid rice was unsuitable for isolation zone in the seed production fields

    文摘:研究了雜交稻花粉對母本不育系回交後代群體bc1 、 bc2 、 bc1f2的主要農藝性狀和育性表現，分析了不育系中出現大量自交結實株的原因，討論了恢復基因滲入對秈、粳不育系純度和雜交稻產量的影響，指出「同質恢」對降低不育系純度的嚴重性和雜交稻作制種田隔離區的不合理性。
  2. It will provide us to further study the function of xanthophyll cycle in photoprotection. the major results are as following : two cdna sequences encoding violaxanthin de - epoxidase were cloned from japonica rice ( jrvde ) and indica rice ( irvde ) with the full - length of 1887bp and 1647bp, respectively. the homology of the open reading frame is 98 % identity between two rvde genes, and more than 60 % identities with those of other species

    本論文從水稻和菠菜中克隆了編碼vde酶的基因，並通過轉基因植物進一步研究了葉黃素循環在熱耗散方面的作用，主要獲得了以下結果：首次從兩個水稻亞種（秈稻和粳稻）中克隆了rvde基因（分別命名為irvde和jrvde ）的全長cdna序列，分別長1647bp和1887bp ，兩者開放閱讀框的同源性為98 ，與其它已知vde基因的同源性在60以上。

  4. Subspecies characteristics in filial generation of cross between indica and japonica under different environments

    不同生態條件下秈粳稻雜交後代亞種特性的比較研究
  5. The genetic correlations of six agronomic characters in some indica - japonica crosses were analyzed using mixed - linear model method. the results indicated that there existed correlations to a certain degree among the measured traits. the phenotypic correlations of plant height with filled grain or seed setting were significant. panicle length with total grains or filled grain, total grains with filled grain or seed setting, and filled grain with seed setting were the same. for panicle length with plant height or seed setting, total grains with filled, and for filled grain with seed setting, genetic correlations were also significant. further analysis, the result showed that genetic correlations between the measured traits were mainly due to domimant effects. in addition, additive correlations were significant for grain weight with panicle length or total grains or filled grain, and for total grains with filled grain

    用混合線性模型方法對秈粳亞種間雜交組合農藝性狀的相關性進行了遺傳研究，結果表明：被測性狀之間大都存在一定程度的相關.其中，株高與實粒數、結實率，穗長與總粒數、實粒數，總粒數與實粒數和結實率，以及實粒數與結實率之間具有顯著的表型相關，總粒數與實粒數，實粒數與結實率，以及穗長與株高和結實率之間具有顯著的遺傳相關.進一步的分析表明，性狀之間的遺傳相關大多歸因於顯性效應，而粒重與穗長、總粒數和實粒數之間，以及總粒數與實粒數之間還具有極顯著的加性相關
