Forage-Yield and Nutrient Quality of New Brown Midrib (BMR) Mutant Lines of Sorghum

The objective of this study was to evaluate the yield, nutrient profile and in vitro digestibility new BMR mutant lines sorghum Indonesia. These were GH2.1, GH2.2, GH2.3, GH4.1, GH4.2, GH4.3 GH4.4. One line (CTY) two national varieties (Super 1 Bioguma) also evaluated as controls. In rumen fermentation measured using Ankom Daisy Fermenter Hohenheim gas test methods, respectively. measurement consisted ten treatments with five replications following a completely randomized design. highest stem sugar content found Bioguma (11.22%) GH4.4 (9.32%) (p<0.05). variety GH2.3 had higher number segments fresh forage yield than Super A greater concentration crude protein (CP) observed for GH.2.1, GH4.1 lowest acid detergent lignin (ADL) (p<0.05), while level non-fibre carbohydrate (NFC) compounds relative feed value (RFV) Furthermore, GH4.2 true (IVTD) (p<0.05) but not significantly different from Bioguma. Regarding characteristics, composition values, values line. Except n-valerate (nC5), significant differences all parameters among cultivars interrelationship between parameters, we medium correlation DMD ADL cellulose (R2 = -0.489 R2 -0.674, respectively). Based on these findings, should be further developed sorghum.
