A diallel cross of twelve cultivars of hexaploid Triticale was made in order to study genie action types for total culm length and for the length of its different segments. Culm length, and four partial lengths of the culm were studied in the F1 and F2 generations. The analysis was made according to the Griffing, Hayman and Jinks models. Heterosis in culm length is mainly due to its upper half. Spanish cultivars have, in general, positive GCA and transmit greater height in crosses, whereas the Mexican ones show a negative GCA effect and have a tendency to decrease in height when crossed. Additivity greatly influences the inheritance of culm length, this influence being lower at the first plant internodes. The environmental component has also a large influence in the phenotypic expression of Triticale height. Dominance is only partial for the five traits studied. The predominant kind of interaction seems to be of the duplicate type. All correlations between culm length and its components are high and positive, especially the genetic ones.
为了研究总穗长和不同节段长度的遗传作用类型，对 12 个六倍体小黑麦品种进行了双列杂交。在 F1 和 F2 代中研究了穗长和穗的四个部分长度。分析是根据格里芬、海曼和詹金斯模型进行的。穗长杂种优势主要来自其上半部分。西班牙品种通常具有正的一般配合力（GCA），在杂交中传递更高的株高，而墨西哥品种则表现出负的一般配合力效应，在杂交时表现出降低株高的趋势。加性对穗长的遗传有很大影响，这种影响在第一植物节间较低。环境因素对小黑麦株高的表型表达也有很大影响。对于所研究的五个性状，显性作用只是部分的。似乎主要的相互作用类型是重复类型。穗长及其组成部分之间的所有相关性都是高度正相关的，尤其是遗传相关性。
