Genotypic Variability for Root Length in Soybean Germplasm

Abstract

Soybean is the second most important oilseed crop of
India. Yellow seeded soybean was introduced in India in
1963-64. Over a period of four decades there has been
an exponential increase in area and production of the crop,
but the productivity is stagnant at around one ton per
hectare (Lal &Rana, 2(00). The lack ofsoybean varieties
to deal with terminal drought is the greatest handicap in
the fight against the drought.
