Evaluasi Karakter Agronomi Galur-galur Generasi Awal Sorgum (Sorghum bicolor (L.) Moench) Hasil Persilangan B-69 x Numbu

Abstract

The objectives of this experiment were to evaluate performance and variability of agronomic characters of 62 F3, 31 BC1P1F2 and 31 BC1P2F2 of early generation lines of sorghum. This research was carried at Leuwikopo Experimental Farm, Bogor Agricultural University, Dramaga, Bogor from February to June 2013. The experiment was arranged in a randomized complete block design augmented with one factor genotype and 12 replications. The agronomic data was analyzed by comparing means of each line to the parental lines B-69 and Numbu. The results showed that the early generation lines showed significant difference with the parental lines, B-69 and Numbu for agronomic characters and yield components. The early generation lines from BC1P2F2 have higher mean value for stem diameter, crop height and biomass weight, compared to B-69 and Numbu, while the BC1P1F2 lines have lower crop height compared to B-69 and Numbu. The panicle weight and seed weight per plant have high heritability value, which allow for further selection.
