    摘要:

    將育種家對(duì)作物性狀表現(xiàn)的綜合評(píng)價(jià)融入作物育種評(píng)價(jià)中,提出了一種基于序相關(guān)的作物育種評(píng)價(jià)性狀特征選擇方法。首先,,從育種數(shù)據(jù)中篩選訓(xùn)練樣本集及候選性狀特征集合,,計(jì)算候選性狀特征集合中各性狀與育種材料評(píng)價(jià)結(jié)果的相關(guān)性和作物在性狀特征間表現(xiàn)的相似性,,然后,,利用計(jì)算的相關(guān)系數(shù)同時(shí)綜合考慮性狀表現(xiàn)的相似性系數(shù),,以期望選擇的性狀特征的相關(guān)性最大,、相似性最小為目標(biāo),,建立基于序相關(guān)的作物育種評(píng)價(jià)性狀特征選擇模型。該模型可為不同育種目標(biāo)提供重點(diǎn)關(guān)注的性狀特征集合,為數(shù)據(jù)化育種提供支持及依據(jù),。利用該方法對(duì)2013年大豆品系鑒定試驗(yàn)中早熟,、中熟、毛豆3類育種材料進(jìn)行了性狀特征選擇試驗(yàn),,結(jié)果驗(yàn)證了方法的有效性,。該方法可以作為育種評(píng)價(jià)方法的前置步驟,與現(xiàn)有的綜合評(píng)價(jià),、模糊綜合評(píng)價(jià)等方法結(jié)合作為性狀特征權(quán)重的確定手段,,提高權(quán)重確定的科學(xué)性。

    Abstract:

    Traditional breeding evaluation methods focus on information of crop traits, while ignoring the previous evaluation results. In order to enhance the efficiency of material evaluation under the condition of large-scale breeding, the comprehensive evaluation of crop traits was integrated into the breeding evaluation, and a method of phenotype feature selection for crop breeding evaluation based on ranking relevance was proposed. Firstly, the training sample set and the candidate feature set were selected from breeding data, and the correlation between the phenotype feature and the results of evaluation and the similarity of the agronomic traits were calculated. Then, considering the characteristics of the maximum correlation coefficient and the minimum similarity, a model of phenotype feature selection for breeding evaluation based on ranking relevance was constructed. The established model can be used for different breeding objectives focusing on collection of characters, and validity of the model was verified by using three kinds of soybean identification trial in 2013. The model also can be used as the preprocess of breeding evaluation to determine the weights of the traits accurately.
