在进行大豆性状相关的研究时,有些研究采用地方品种,有些研究采用杂交分离世代的材料,研究的设计也各不相同,因此结果的波动也较大。因为性状间的相互关系,是一定的大豆品种群体或杂种群体,在特定的自然条件下或栽培条件下的反应。在品种及栽培水平改变的情况下,相关关系可能随之产生变化。同时,以往研究性状相关所基于的取样单位不同,因此,受环境的影响不同,梢关结果当然会有出入此外,相关系数 r 值,只表示性状间的简单直线关系。而实际上大豆性状间的关系综复杂,有的并 In studies related to soybean traits, some studies used local cultivars, others used hybridization to separate generations of material, and studies were designed differently, resulting in greater variability in the results. Because of the interrelationship of traits, it is the response of a certain soybean or hybrid population under certain natural or cultural conditions. In the case of changes in the level of varieties and cultivation, the relationship may change. In the meantime, the sampling units used to study trait correlation in the past are different. Therefore, depending on the environment, there are of course different results. The correlation coefficient r is only a simple linear relationship between traits. In fact, the relationship between the characteristics of soybean complex, some and
