Growth Pattern and Classification of Soybean Under Semi-sodic Soils

Wide range of variation was observed in sixty genotypes of soybean evaluated under semi-sodic soil condition. Euclidian Non Hierarchical cluster analysis resulted in formation of four clusters. Cluster I exhibited the determinate habit, while cluster IV comprised indeterminate types. Cluster II and III both were found to be semi-determinate type. The semi-determinate growth habit recorded less biological yield in comparison to both determinate and indeterminate types but produced more seed yield and recorded the highest harvest index. The study demonstrated that selection of genotypes with semi-determinate growth habit would result in development of high yielding soybean lines under semi-sodic soils.
