Description The lignin content of forage crops significantly affects the livestock’s forage intake and its dry matter digestibility.
The brown midrib (bmr) trait is known for its association with a reduced lignin content and increased digestibility.
Pearl millet inbreds having the bmr trait were derived from two populations ICMV bmr and WRajPop bmr via continued
selfing up to 6–8 generations. The results from the crosses revealed the presence of the same single recessive gene
that controlled the bmr in both the populations. The stable expression of the bmr gene in the new genetic background
indicated that there was no effect of modifier genes. Four inbreds were identified with the stable expression of bmr
(three in ICMV 155 and one in the WRajPop background) with a high biomass potential, which can serve as a bmr source
in future pearl millet forage breeding programmes.
