Abstract

Abstract: This research aimed to find out interaction of genetic source×harvest time×storage time in 10 mutant varieties of sweet sorghum to support sorghum bioindustry. The study was carried arranged in split-split plot design with 3 replications. Main plot was variety which consists of 10 mutant varieties with 2 control varieties (Numbu and Super 1). Whereas subplot was harvest time consisted of 3 levels (75, 90 and 105 days after planting/DAP). Sub-subplot was storage times (0, 4, 8 days after harvest/DAH). Mutant varieties influenced juice volume and sugar yield. Harvest time influenced brix content and juice volume. Storage time, interaction of variety×harvest time, variety×storage time, and harvest time×storage time had significant effects on all observed traits. Interaction between variety×harvest time×storage time) affect the brix content. High brix content can be gained at harvest time of 90 DAP and with storage time of stalk at 4 DAH. There were 4 mutant varieties of sweet sorghum with high brix content, namely GMS-1 (23, 05%), GMS-3 (22, 88%), GMS-8 (22, 75%), GMS-2 (22, 62%) and GMS-6 (22, 08%). Mutant variety of GMS-5 had the highest juice volume in all harvest times at 0 DAP. The mutant variety GMS-9 had stable sugar yield in all three harvest and storage times.
