F3 generation of groundnut
-
At the same time, the breeding lines from the advanced generations are also used as parental lines for developing commercially exploitable heterotic hybrids. But, most often the source of early generations i.e., F3, F4, F5 and F6 segregating populations offer wider opportunities for achieving high success, because of wider genetic base.

Studies on genetic parameters for growth parameters, traits related to wue, yield and yield attributing traits in F3, F4, F5 and F6 segregating generations of the cross NRCG 12273 × ICG 12370 in groundnut (Arachis hypogaea L.)

Variability studies were carried out for different characters of groundnut derived from four crosses viz., Kadri-9 x GPBD-4, ICGV-00351 x GPBD-4, Kadri-9 x Sunoleic-95R, ICGV-00351 x Sunoleic-95R. Results revealed that the presence of moderate to high PCV and GCV for most of the traits, further a high heritability coupled with high genetic advance was also observed for these traits indicating the involvement of additive gene action in controlling these traits making selection effective.

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.

In the present investigation, estimates of genetic variability, heritability and genetic advance were assessed for nine different characters in the F3 population derived from four groundnut crosses, viz., CO 7 × VRI Gn 6, TMV 2 × VRI Gn 6, TMV Gn 13 × VRI Gn 6 and VRI 2 × VRI Gn 6. Considering the mean performance, the cross derivative TMV Gn 13 × VRI Gn 6 registered superiority for the characters viz., 100-pod weight (g), 100- kernel weight (g) and sound mature kernel (%).

Late leaf spot caused by Phaeoisariopsis personata is the most important disease on groundnut worldwide. Although fungicide treatment is effective, it is uneconomical to use because of high cost, hazardous to environment and insensitivity build up in pathogen. The deployment of resistant cultivars is a better option to control LLS disease in groundnut the investigation was undertaken to determine the mode of genetic inheritance of LLS resistance in two F2 and F3 segregating populations of groundnut.
