  1. Only the additive genetic variance is transmissible by seed.

    僅僅加性遺傳方差是由種子遺傳的。
  2. The additive genetic variance of the same character, estimated from the covariance of half sibs, was 0. 9602.

    從半同胞協方差估計出來的，同一性狀的加性遺傳方差為09602。
  3. Additive variance was higher than dominance variance, which indicates quantitative inheritance.

    加性的變異高於顯性的變異，表明是數量遺傳。
  4. Additive genetic variance

    加性遣傳方差
  5. The additive genetic variance of the same character, estimated from the covariance of half sibs, was 0. 9602

    從半同胞協方差估計出來的，同一性狀的加性遺傳方差為0 9602 。
  6. ( 4 ) the results of qtl mapping indicated that the inheritance of yield traits was very complex, the explanation as follows : additive effects except for sterile spikelet number per spike ( ssns ), qtls of additive effects were tested for all other traits, with 10 qtls for 1000 grain weight ( kgw ). the large variance of the effect values and the contribution rate of qtls indicated that the effects are difference for different qtls

    14 。 （ 4 ）通過對產量性狀qtls作圖，發現產量性狀的遺傳非常復雜，可以從4個方面說明：加性效應除不孕小穗數外，各性狀均檢測到了表現加性效應的qtls 。其中，在各環境聯合分析下，檢測到了10個千粒重qtls ，各qtls的加性效應值和對群體變異的貢獻率也存在很大差異，說明不同的qtls不是等效的。
  7. The cyclic estimation approaches of chirp signals in additive nose or multiplicative noise are proposed, it presents a way for the parameters estimation of zero mean amplitude chirp signals. the estimation performances in the additive noise or multiplicative noise are analyzed by the first order perturbation analysis method, and the error variance expressions of the parameters estimation under large samples are derived

    針對加性噪聲情況及存在乘性噪聲的情況，提出了線性調頻信號參數的循環平穩估計方法，解決了零均值乘性噪聲的信號參數估計問題，並採用一階擾動分析方法，對兩種噪聲情況下的估計性能進行了分析，推導出了各參數的估計誤差方差公式。
