Nine soybean genotypes comprising of six lines, one variety and its two mutant lines were grown in five locations to stud) the genotype-location interaction. Analysis of variance showed significant differences among genotypes and among location; for the grain yield. The mean yields among genotypes ranged from 1244.74 kg/ha to 1986.65 kg/ha. The genotype-locatior interaction for the grain yield was highly significant. The partitioning of genotype-location interaction into heterogeneity ol regressions and deviations of regression, revealed that the mean square for heterogeneity of regression was not significant This suggested that the mean yield variations among genotypes across locations was mainly due to the nonlinear effect.


Sembilan genotip kacang soya yang terdiri daripada enam warisan, satu varieti dan dua warisan mutan telah ditanam di lima lokasi untuk kajian interaksi genotip-lokasi. Analisis varians menunjukkan terdapat perbezaan yang bererti antara genotip dan antara lokasi bagi hasil bijirin kacang soya. Min hasil bijirin antara genotip adalah dalam julat antara 1244.74 kg/ha dan 1986.65 kg/ha. Interaksi genotip-lokasi bagi hasil bijirin adalah sangat bererti. Daripada pemisahan min kuasadua interaksi genotip lokasi kepada heterogen antara regresi dan penyisihan daripada regresi, didapati min kuasadua untuk heterogen antara regresi adalah tidak bererti. Ini menunjukkan bahawa variasi min hasil antara genotip di lokasi-lokasi yang berbeza adalah disebabkan oleh kesan bukan-linear.
