  1. Secondly, based on the microbeam analytical technique, on the one hand, through investigating the characteristic of major elements in the mantle minerals the author acquired the static information from mantle ; on the other hand, through multi - point analysis of a part of the minerals from mantle, the auther got dynamic information from mantle. finally, generalizating the fruits of this study and predecessors, the autor holds that the constituents of lithospheric mantle possibly includes spinel lherzolites, clinopyroxenites, websterite, dunite, harzburgites, garnet lherzite, phlogopite lherzite, eclogites, clinopyroxene megacrysts ; compared with east china and north china platform, the research field mantle shows the characteristics of higher degree of partial melting processes and more depleted mantle ; the. upper mantle beneath north hetian area is heterogeneous, with a tendency of deficit in a12o3 and lree from kaliyang in west hetian to the river basin of kalakshi river and yulongkashi river ; the subduction of the crust beneath north hetian has ever occurred in geological history and caused the mixing of mantle - crust ; the depth of the origination of basaltic magmas beneath north hetian exceeds 73km ; the thickness of the lithosphere beneath the research area amounts to 204. 9km ; the mantle beneath north hetian has geological condtions for forming diamond deposits

    最後,綜合區幔源礦物和地幔巖石的特徵以及地球物理資料,得出如下結論:區上地幔的物質組成有尖晶石二輝橄欖巖、二輝巖、單斜輝石巖、純橄欖巖、方輝橄欖巖、石榴石二輝橄欖巖、金雲二輝橄欖巖、榴輝巖;與中國東部以及華北地臺上地幔相比,研究區上地幔具有富集主元素中相容元素和虧損其中的不相容元素的特徵,局部熔融程度較高;上地幔存在橫向和縱向的不均一,從西部的克里陽到喀拉喀什河和玉龍喀什河流域, al和lree富集程度呈下降趨勢,不同來源的相同礦物中主元素的含量差異較大;地質歷史時期這里可能發生過地殼俯沖並產生殼幔混合作用;玄武巖漿的起源深度73km ;從幔源重砂礦物的溫壓估算結果,可以推斷出巖石圈厚度可達204 . 9km ;綜合巖石圈物質組成特徵、巖石圈熱態、地幔溫壓態、氧逸度以及幔源巖石和幔源礦物的化學成分,認為研究區具備了金剛石成礦地幔地質條件。
  2. 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

  3. Twenty f1 combinations crossed among 5 varieties and strains different in fiber properties according to complete diallel crossing design were used to evaluate the heterosis and gene action of boll weight and lint percentage in high quality fiber property varieties in upland cotton in 1998 1999 for two year successively at nanjing. it was indicated that there existed small interactions with the environmental factors without maternal effects and the additive gene effect was in chief, attaining to 51. 2 % and 65. 4 % respectively for boll weight and lint percentage. the dominant effect was also in higher rate, 32. 6 % and 16. 8 % respectively. the population mean heterosis of boll weight and lint percentage over the mid - parental mean were relatively prominent 13. 3 % and 3. 5 % respectively in extreme significance. however, boll weight showed no significantly surpassing parental f1 heterosis over the better parent based on population mean ( 2. 0 % ) ; while the lint percentage expressed significant negative heterosis value ( - 2. 1 % ). the gene actions were in conformity with the heterosis expression. it was shown clearly that the f1 combinations crossed between parents with similar performances had relatively high dominant effects and significant positive f1 surpassing parental heterosis ( f1 heterosis over the better parent ) ; while no f1 combination crossed between the parents with prominent mutual difference surpassed the higher parent in yield components, which indicated that among those parents with less difference and close relationships, there still existed sufficient genetic variation or certain mechanism for creating variation and achieving greater advances in breeding. correlation analyses also indicated that there still existed severely undesirable negative correlation between yield and fiber properties as well as the difficulties for their simultaneous improvements

    利用5個具有不同纖維品質的品種(系)配製完全雙列雜交組合20個,通過親和f1的2年隨機區組試驗發現產量的鈴重和衣分與環境的互作效應小,不存在體效應,並以加遺傳效應為主,分別占表型方差的51 . 2 %和65 . 4 % ;顯遺傳效應所佔的比率也較高,分別為32 . 6 %和16 . 8 % .鈴重和衣分的群體平均優勢較大,分別為13 . 3 %和3 . 5 % ,達到了極顯著;鈴重的超親優勢為2 . 0 % ,不顯著;衣分為顯著的負值( - 2 . 1 % ) .遺傳分析與雜種優勢結果一致.具體表現在產量上,親相當配製的組合雜合顯較高,其超親優勢正向顯著,而極值親(差異較大)所配組合沒有超過高親的.這表明親差異小、親源關系較近的親中仍然存在足夠的遺傳變異或某種機制以創造變異使育種取得更大的進展.相關分析表明了仍然存在嚴重的品質與產量的負相關,遺傳改良的難度較大
