Morphogenetic Evaluation for Pod Yield and its Components in Early Spanish Genotypes of Groundnut (Arachis hypogea L.).
Saeed Ahmad Shah Chishti,
Sixteen early maturing genotypes of groundnut showed significant variation for all characters studied expect 100 kernal weight. Phenotypic Coefficient of Variation (PCV) was higher than Genotypic Coefficient of Variation (GCV) for all the characters. High heritabilities (h2) for days taken to flowering and maturity were found very high. At genotypic level all the traits under study except days taken to maturity exhibited significant positive association with pod yield while it showed significantly negative correlation. Sound Mature Kernal (SMK) %age by weight longwith shelling %age and No of pods per plant had fairly high h2, high Genetic Advance (G.A.), significantly positive genotypic correlation and positive direct effect on pod yield. Hence selection for these traits would be effective in improving pod yield and oil contents in early maturing genotypes.
