This research compared tall and dwarf near-isogenic F1 hybrids to attempt to determine if there were deleterious effects of the d 2 dwarfing gene that might account for the lack of release/cultivation of dwarf pearl millet cultivars. Dwarf isohybrids on average yielded less than the tails, because of a smaller average seed size combined with a similar grain number per unit area. There was, however, a larger contribution of background genetic variation (pollinator, male-sterile, and interaction effects) to hybrid variation for nearly all characters measured, including seed size, than there was of the dwarfing gene. Selection of dwarf parents capable of producing hybrids with equal seed size and yield to that of tall parents should not be difficult publisher: Springer Verlag date: 1990 type: Article type: PeerReviewed format: application/pdf language: en identifier: http://oar.icrisat.org/4968/1/TAG_79_521-524_1990.pdf identifier: Bidinger, F R and Rnju, D S (1990) Effects of the d2 dwarfing gene in pearl millet.
