摘　　要：本研究采用Griffing方法I,利用6×6完全双列杂交,对6个不同类型的冬小麦品种的子粒钾含量的遗传机制进行了初步分析。结果表明:不同品种子粒钾含量的一般配合力(GCA)效应,特殊配合力(SCA)效应和反交(R)效应,均达到极显著水平。钾含量的广义遗传力为91.18％,狭义遗传力为68.01％。冀麦36是较为理想的育种亲本。Genetic mechanism of grain kalium content in winter wheat was studied by applying 6×6 complete di-allel cross and Griffing I analysis method. The results showed that there was significant variances in general combining ability (GCA) ,special combining ability (SCA)and reciprocal cross (R) in grain kalium content. The broad and narrow heredity of grain kalium content was 91. 18% and 68. 01% respctively of the tested varieties,Jimai 36 was a preferable parent material.
