  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. The results indicated that opposite maize had widespread heterosis like alternative maize ; yield advantage of opposite f1 ( alternative alternative ) was better than that of f1 ( opposite opposite ) and f1 ( alternative opposite or reverse ) ; general combining ability of yield characters was decreased by opposite characters transfer maize, but alternative maize with opposite genes has high general combining ability, so that on the opposite maize breeding, alternative inbred lines with different opposite genes can be parents for breeding hybrid lines ( alternative alternative ) and hybrid varieties with more seeds and high yield can be obtained

    結果表明：對生玉米同互生玉米一樣具有普遍的雜種優勢，在產量性狀上f1對生株優勢互互組合大於對對組合和對互（互對）組合；對生性狀的轉育對產量性狀的一般配合力有降低效應，而含有對生基因的互生玉米具有較高的一般配合力效應，因此，在對生玉米育種中可以利用含有不同對生基因的互生自交系作親本來組配雜交組合（互互） ，從而獲得較高的制種產量和高產的對生雜交種。
  3. " xiyuan4 ", a b. olereacea l. and " 2001817 ", a b. napus l. were bred by southwest agricultural university. here using them as materials, we studied and explored thoroughly the dna and cdna sequences of thl2 gene and mod gene with bioinformatical methods. for the first time, based on sequence data, we analyzed the structure, heredity and variation of the dna sequences encoding thl2 and mod, and foresaw the molecular mechanism in self - incompatibility signal process

    本研究以西南農業大學繁育的高度自交不親和的『西園4號』甘藍和『 2001817 』油菜為試材，採用生物信息學的方法全面研究和探索性的分析了thl2基因和mod基因的dna與cdna序列，首次從序列數據出發研究這兩個編碼基因的結構與遺傳變異，以及在自交不親和性信號轉導中的作用機理
  4. Question - answer is the key to the teaching - learning activities, but the network ' s getting involved hinders this two - way exchange between learners and instructors. thus, research and developing question - answering system, that is, how to giving learners satisfied reply efficiently is the core mission to the development of web - based distance education
