Abstract
Two red-grained accessions, 8198 and 8207, of Triticum aestivum L with tolerance to preharvest sprouting and a highly susceptible white-grained cultivar, WL711, were crossed to investigate the inheritance of preharvest sprouting tolerance. The data on F1's, F2's, backcrosses, and parents revealed that preharvest sprouting tolerance was controlled by a single dominant gene. Both accessions had the same gene for preharvest sprouting tolerance Five amber-grained and preharvest sprouting-tolerant BC1F3 progenies were derived from two crosses. The matenal developed will be of immense value in breeding amber-grained spring wheats that are tolerant to preharvest sprouting.
