  1. 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性狀的品種(系)配製完全雙列雜交組合20個,通過親本和f1的2年隨機區組試驗發現產量性狀的鈴重和衣分與環境的互作效應小,不存在母體效應,並以加性遺傳效應為主,分別占表型方差的51 . 2 %和65 . 4 % ;顯性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.具體表現在產量性狀上,親本相當配製的組合雜合顯性較高,其超親優勢正向顯著,而極值親本(差異較大)所配組合沒有超過高親的.這表明親本差異小、親源關系較近的親本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
  2. The result showed that appraise and keep the same with traditional output result with weighting related degree to peanut breed, 100 - seed weight, 100 - grain weight, yield per plant, full - pod rate and offer the rice rate are dominant in affecting yield, but main stem height and side branches length are not dominant in affecting yield, the method is simple, easy to master

    結果表明:用加權關聯度對花生品種進行評價與用傳統產量比較結果一致,百果重、百仁重、單株生產力、飽果率、出米率在影響產量諸因素中佔主導地位,主莖高、側枝長對產量影響較小,且方法簡單,容易掌握。
