Selection for grain yield in low nitrogen fertility conditions uri icon

abstract

  • A selection experiment was conducted with three random-mating populations of sorghum (Sorghum bicolor (L.) Moench). The selections were made simultaneously in high and low nitrogen fertility for grain and biomassproductivity. Yield trials of selected S3 and S4 bulks showed no advantage of selection in low fertility. These results indicate that breeding sorghum in low nitrogen fertility is not necessary; only the testing of advance generation progenies in low nitrogen environment may besufficient to ensure that the newly selected cultivars perform reasonably' well in the low fertility environments
