Evaluation of Sweet Sorghum Hybrids for Juce Yield, Ethanol Yield and its Attributing Traits

Abstract

An investigation was carried out to assess the extent of heterosis for  juice yield and its attributing traits in 45 new hybrids of sweet sorghum developed by crossing 3 male sterile lines with 15 restorer in L x T mating design and  were sown in randomized block design (RBD) with three replications during Kharif 2018 at Botany Farm, Post Graduate Institute, M.P.K.V., Rahuri. The significant average heterosis, heterobeltiosis and standard heterosis recorded for total biomass, juice yield and its contributing characters in fourty five crosses. The cross CMS-1409 x RSSV-512 showed the highest significant average heterosis (224.84%) and heterobeltiosis (286.36%) for juice yield. The extent of standard heterosis observed for juice yield over the check, CSH-22SS was upto 59.15 per cent. The highest significant standard heterosis was recorded by the cross CMS-1409 x RSSV-512 (59.15%), followed by cross ICMS-479 x RSSV-355 (43.58%) and CMS-1409 x RSSV-355 (24.30%). Based on per se performance and heterotic performance for yield and its principal components in the F1 hybrids the cross combinations viz; CMS-1409 x RSSV-512, ICMS-479 x RSSV-355 and CMS-1409 x RSSV-499 CMS-1409 x RSSV-498 and CMS-1409 x RSSV-355 were appeared to be promising.
