Abstract
The innovative method to assess the true genetic potentialities of inbreds was an effective way to identify potential inbreds. The pooled analysis methods viz., simple pooled gca method, per cent pooled gca method and weighted pooled gca method was used to calculate overall combining ability. In the present study, two heterotic populations were crossed in the line × tester method. These innovative methods were used to assess overall combining ability based on pooled analysis using eight different economic traits in baby corn. In Population A, the inbreds viz., P48, P41, P30, P14 and P50 were considered as top five for yield-related traits. Likewise, the inbreds viz., H95, H81, H51, H20 and H97 belonging to Population B were best combiners for yield and its related traits.
Keywords: Combing ability, simple pooled gca method, per cent pooled gca method, weighted pooled gca method.
