Cause and Effect Relationship Among Seed and Fodder Yield Traits in Wild and Cultivated Oat
Present investigation was carried out during Rabi, 2018-19 to estimate cause and effect relationship among seed and fodder yield traits in eight accessions of Avena species including seven wild viz., A. barbata (HFO-58), A. orientalis (HFO-103), A. byzantina (HFO-498) and A. strigosa (HFO-505), A. byzantina (HFO-60), A. sterilis (HFO-508), A. sterilis (HFO-878) and one cultivated namely A. sativa (HJ-8). The accessions were evaluated in a randomized block design with three replications. Analysis of variance revealed significant differences among the accessions for all the traits studied. High heritability associated with high genetic advance was recorded for most of the traits suggesting the role of additive gene action. Number of tillers per plant, dry matter yield per plant, biological yield per plant, harvest index, seed length and protein content (%) showed significant association with seed yield per plant. Days to 50% flowering, leaf area, plant height, green fodder yield per plant, biological yield per plant, harvest index, seed length and 1000 gain weight had substantial direct effects on seed yield per plant. On the basis of overall performance, HFO-498 (A. longiglumis), HFO-505 (A. strigosa) and HFO-878 (A. sterilis) accessions of wild species were found to be superior over the cultivated A. sativa. Thereby, suggesting that these accessions can be utilized in oat improvement programme in near future.
