Title : Heterosis For Fodder Yield and its Contributing Traits in Dual Purpose Sorghum (Sorghum Bicolor (L.) Moench) Hybrids

Abstract :

An experiment was conducted to assess the extent of heterosis for fodder yield and its contributing traits in sorghum (Sorghum bicolor (L.) Moench) crosses using line x tester mating design. Thirty hybrids derived from mating five testers with six lines in L x T design along with their parents and two checks viz., CSH 15 R and CSV 22 R were evaluated at Sorghum Research Station, VNMKV., Parbhani (Maharashtra), India. Observations were recorded on randomly selected 5 five plants in each replication for grain yield and its contributing characters. Amongst 30 hybrids evaluated, three hybrids viz., Phule Anuradha x PBMR 3, Phule Anuradha x PBMR 1 and ICSR 196 x PBMR 3 recorded lowest negative heterosis percentage for days to 50% flowering over standard hybrid check (CHS 15 R), varietal check (CSV 22 R) and better parent. In addition the crosses; Parbhani Moti x PBMR 5, PMS 71B x PBMR 5, CSV 29R x PBMR 3, MS 104B x PBMR 3, ICSR 196 x PBMR 3 and Phule Anuradha x PBMR 3 possessed significantly desirable heterosis and per se performance for fodder yield per plant. Parbhani Moti x PBMR 5, PMS 71B x PBMR 5 and ICSR 196 x PBMR 3 have also shown good perse performance and heterosis for fodder contributing traits plant height, no. of leaves, leaf area, biomass and stem girth. Hence this cross is found tobe promising for fodder quality and palatability traits. While hybrids CSV 29 R x PBMR 3, Parbhani Moti X PBMR 4, Phule Anuradha x PBMR 4, Parbhani Moti x PBMR 1 and MS 104B x PBMR 3 expressed significant superiority for heterobeltiosis and standard heterosis for grain yield. Cross CSV 29 R x PBMR 3 and Parbhani Moti x Pbmr 5 are promising for developing dual purpose genotypes.
