SPV-2018 (IC0612063; INGR15027), a Sorghum {Sorghum bicolor(L.) Monech.) Germplasm with High Digestibility (IVOMD %), Low Lignin Content and Brown Midrib (bmr)

摘要

The significance of brown midrib mutation in sorghum is that it greatly reduces lignification and cell-wall concentration, increases digestibility, and increases voluntary intake of feed by ruminants. Genetic control of the lignification process through use of brown midrib (bmr) mutations has offered the most direct and productive approach to reducing lignin concentration and increasing digestibility of sorghum. Digestibility of fodder is the most important forage quality parameter which helps in better absorption of the feed taken in by the animal. It is estimated that a 1% increase in digestibility increases milk yield by 5%, resulting in higher income for farmers (Rao and Hall, 2003; Kumaracharyulu et al, 2014).
