Abstract
The development of sorghum varieties have been conducted with several purposes such as to obtain grain sorghum, sweet sorghum, forage sorghum, and biomass sorghum. Recently, sorghum breeders try to develop sorghum type for bioenergy. Unfortunately, there is a little information on genetic variability especially that of biomass sorghum. The objectives of this study were to evaluate the genetic components of 20 different sorghum genotypes, to estimate the broad sense of heritability value, and to assess the economic yield for biofuel and feed. There were 20 sorghum genotypes as GH-1, GH-2, GH-3, GH-6, GH-7, GH 9, GH 10, GH 11, GHP-1, GHP-3, GHP-11, P/I WHP, P/F 5-193-C, PF 10-90-A, P/I 150-21-A CYMMIT, Mandau, Numbu, Pahat, Talaga Bodas, UPCA. Treatments were arranged in randomized block design with 3 reps. Variables observed in this study were root dry weight, leaf number, leaf dry weight, stem dry weight, inflorescence length, and yield components as seed size and seed weight. Data were analysed by using analysis of variance and broad sense heritability. Analysis of variance showed that genotypes were significantly different based on the variables observed. Plant height, panicle length, and seed size showed high broad sense heritability i.e. 90.2, 92.6, and 92.3% respectively. On the other hand, stem diameter, seed number and seed weight have low broad sense heritability i.e. 52.3, 54.5, and 55.7% respectively. Keywords: biomass, broad sense heritability, genetic variability, sorghum
