Abstract:
The present study was undertaken with a view to investigate narrow-sense heritability and genetic advance of seed yield and yield attributing traits in medium duration pigeonpea. The experimental material comprised of six generations viz., P1, P2, F1, F2, BC1 and BC2 of five crosses of pigeonpea, namely of GRG 152 × GJP 1, GRG 152 × AGT 2, JSP 6 × GJP 1, JSP 6 × BDN 711 and WRG 173 × BDN 711. All five crosses were evaluated using Compact Family Block Design at two different agro-climatic zone viz., South Saurashtra agro-climatic zone and North Saurashtra agro-climatic zone during Kharif 2021-22. The observations were recorded for nine characters viz., days to flowering, days to maturity, plant height (cm), number of branches per plant, number of pods per plant, number of seeds per pod, length of pod (cm), 100-seed weight (g) and seed yield per plant (g) on five randomly selected plants in each replication for P1, P2 and F1; twenty plants for F2 and ten plants for BC1 and BC2. High heritability coupled with moderate genetic advance was observed in JSP 6 × GJP 1 at both locations, whereas for GRG 152 × AGT 2 at Junagadh for number of branches per plant; for GRG 152 × GJP 1 at Kukada for number of seeds per pod and, for GRG 152 × GJP 1 at Kukada for seed yield per plant. Almost characters showed high heritability with low genetic advance.
