Transgressive segregation study in F3 population of four groundnut crosses

Transgressive segregation is a very important phenomena where the segregating individual will possesses the value for a character which is exceeding the better parent. In the present study transgressive segregants were studied in four crosses for SCMR(SPAD Chlorophyll meter reading), SLA (specific leaf area), total biomass per plant, shoot weight per plant, root weight per plant, shelling out-turn per plant, harvest index per plant, pod yield per plant and kernel yield per plant. All the characters under study showed transgressive segregation in all the four crosses. This indicates that the parents posses 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 and handling of these segregants evaluating the segregants for different characters along with selection for yield to arrive at a desirable plant type through selection in later generations. | Transgressive segregation study in F3 population of four groundnut crosses
