A mutant form was found in an M(2) population of wheat Triticum aestivum L. em. Thell. (aestivum group) 'Seneca'. The population was derived from soaked grains treated with 3.2 kilorads of gamma rays. The first and second internodes below the spike were reduced in length 33 and 15 percent, respectively, and the total height was 18 percent shorter than the prototype. The flag leaf sheath was normal in length resulting in spike placement below the flag leaf lamina. Segregation data suggest that one dominant gene controls this character. The canopy structure of a population of mutant plants is different from that of the normal type; therefore, this mutant can be used to evaluate light interception and physiological aspects of crop productivity.
在小麦（Triticum aestivum L. em. Thell.，aestivum 组）“塞内卡”的 M（2）群体中发现了一种突变体形式。该群体源自用 3.2 千拉德的伽马射线处理过的浸泡过的谷物。穗下第一和第二节间分别缩短了 33%和 15%，总高度比原型矮 18%。旗叶鞘的长度正常，导致穗部位于旗叶叶片下方。分离数据表明，一个显性基因控制着这个特征。突变体植物群体的冠层结构与正常类型不同；因此，这种突变体可用于评估作物生产力的光截获和生理方面。
