correlated traits 中文意思是什麼

This study was conducted to examine the interrelationship of 10 seed vigor traits in 12 wheat genotypes through variance, co - variance and path coefficient analysis, to determine broad - sense heritability, and to estimate genetic advance under selection. the genotypes showed significant difference for all traits, except for percentage of normal seedling. genetic correlation between conversion efficiency of seed reserve, electrical conductivity with other traits were not significant, showed that selection for any of them might be possible without hampering any other traits. however path coefficient analysis indicated that conversion efficiency of seed reserve, seed reserve utilization ratio have strong direct effect in affecting seedling weight, and that mean germination time has significantly negatively correlated in affecting gi. moderate to high estimates of broad - sense heritability, genetic coefficient of variation and expected genetic advance were obtained for electrical conductivity, germination index, mean germination time, seed dry weigh, seedling dry weigh, seed reserve depletion ratio indicating the possibility for improving these traits
本研究利用12個普通小麥品種對10個種子活力性狀的遺傳變異和相關研究，表明除正常幼苗百分率外，其餘種子活力性狀在品種間均存在顯著的差異.種子貯藏物質轉換效率、電導率兩個性狀間及與其它性狀均無顯著的遺傳相關，因此對他們的選擇不會影響到其它性狀.通徑分析表明幼苗干重主要取決于種子貯藏物質轉換效率、種子貯藏物質利用速率;發芽指數主要由平均發芽時間決定.電導率、發芽勢、幼苗干重、種子干重、發芽指數、種子貯藏物質消耗比率6個性狀表現中到高的遺傳力、遺傳變異系數和相對遺傳進展，指明通過遺傳育種手段改良這些性狀是可能的 -
Quality besides micronaire value and elongation of relevance not significant, other quality traits of both showed significant level ; yield and quality traits associated single boll weight and the first half of the average length uniformity index significantly related, and the breaking strength of correlation was significant, and micronaire value was negatively correlated ; lint and micronaire value elongation reached significant levels and a very significant level, and on average half the length uniformity index, breaking strength of correlation was significant but was negatively correlated
品質性狀間除了麥克隆值與伸長率的相關性不顯著之外，其餘品質性狀間均呈現出極顯著水平；產量性狀與品質性狀的相關性中單鈴重與上半部平均長度、整齊度指數相關性顯著，與斷裂比強度相關性極顯著，與麥克隆值呈負相關；衣分與麥克隆值、伸長率分別達到顯著水平和極顯著水平，與上半部平均長度、整齊度指數、斷裂比強度等相關性極顯著但呈負相關。
