SUMMARY

The present investigation was carried out to estimate morphological variation for green fodder yield and related traits in sewan grass (Lasiurus sindicus Henr.) for 273 accessions. The observations were recorded for eleven characters during kharif-2017 at Agricultural Research Station, Bikaner. Out of 273 accessions, metroglyph analysis study was done for 30 best accessions based on green fodder yield per plant. Among all the characters, two characters viz., number of tillers per plant and dry matter yield per plant showed high phenotypic coefficient of variation, respectively. These two characters were represented as glyph for metroglyph analysis; other nine characters were represented as rays on glyph at various lengths at different positions on the basis of their means criteria. On this basis, the 30 accessions were classified into seven clusters which had low-yielding, medium-yielding and high-yielding groups. The accessions from the low and high groups, respectively, generally possessed low and high values for each of the characteristics. The accessions from the medium-yielding group were intermediate for most of the characters. It can be also inferred that the scoring procedure would be utilized in the preliminary screening of a large number of genotypes for selection of accessions with desirable combination of various characters influencing the number of tillers per plant with dry matter yield per plant in sewan grass. Highly diverse accessions, on the basis of their total index score; (RLSB 1-41, RLSB 10-1, RLSB 4-41, RLSB 4-37 and RLSB 10-17) were identified.
