Morpho-physiological characterisation of quadra and pentafoliate soybean[Glycine max (L.) Merrill] genotypes for yield potential

Abstract

A field experiment was carried out during Kharif 2019 at the Main Agricultural Research Station (MARS),University of Agricultural Sciences, Dharwad to study Morpho-physiological characterisation of quadra and pentafoliatesoybean genotypes for yield potential. The experiment was laid out in Randomized block design with eight genotypes (DSb31, DSb 21, DSb 23, DSb 32, DSb 36, JS 335, JS 93-05 and DSM considering each these genotypes as individual treatmentsand laid out in four replications. The study revealed that, genotypes DSb 31 and DSb 36 were with quadra/pentafoliateleaves and the presence of wide genotypic variation with respect to bio-physical and yield characters. Among the genotypes,DSb-21 followed by genotypes DSb 23, JS 335 and DSb 31 (quadra/pentafoliate leaves) exhibited superiority over rest ofthe genotypes in yield while giving a better response to most of the yield contributing characters such as higher leaf area,higher dry matter accumulation and higher photosynthetic rate. It is inferred from the present investigation that, genotypeDSb 31 (quadra/pentafoliate leaves) is having the advantage of a greater number of leaflets per plant, of short duration, ofgood height and bears a greater number of four seeded pods as compared to some high yielding soybean genotypes like DSb21, JS 335 and DSb 23
