The crop cultivars targeted for drought prone areas need to combine
drought tolerance and high yield. The present study was conducted to
assess the performance of three selected pearl millet landraces, four
exotic elite populations and their 12 crosses. They were evaluated for
yield, yield components and a drought susceptibility index that was
calculated using yield data from drought and non-drought environments.
In the non-drought season, the exotic populations had
significantly higher grain yield than landraces. However, in the severe
drought season, the landraces produced significantly greater biomass,
grain and stover yields than elite populations. There was a strong
relation between panicle size and ability to produce panicles and delay
in flowering under severe stress. The biomass and stover yield of
crosses was significantly better than parental populations under both
drought stress and near-optimum conditions. The elite populations
were most sensitive to drought while crosses were as drought tolerant
as landraces because they combined larger panicle size of exotics and
lesser delay in flowering of landraces. The results indicated that it is
possible to combine drought adaptation with high yield potential
through hybridization between adapted landraces and elite genetic
materials.
