Studies on transgressive segregation in three selected F2 populations of groundnut (Arachis hypogaea L.)

Abstract: Transgressive segregation is a phenomenon where the segregating individual will possesses the value for a character which is exceeding the better parent. In the present study transgressive segregants were observed in all the three crosses for plant height, branches per plant, days to first flowering, pod per plant, pod yield per plant and kernel yield per plant, shelling percentage and sound mature kernel percentage. Progenies of the cross TMV2 × ICGV-00350 recovered highest number of transgressive segregants for yield traits. Occurrence and recovery of such transgressive segregants indicates that the parents possess different alleles and genes governing respective characters from which it could be inferred that there is a lot of scope to bring in beneficial alleles into a single genotype through rigorous selection. Better and stringent selection procedure can pyramid the quantitative alleles in to single or few genotypes to enhance the productivity of groundnut which is major concern in India.
