Pre-harvest sprouting (PHS), which is the precocious germination of the grains in the spike before it is harvest, is the serious problem in the reduction of end-use quality in wheat. In this study, the relationships among PHS tolerance, agronomic and grain characteristics in Korean wheat cultivars were evaluated for two years to improve PHS tolerance in Korean wheat breeding programs. Grain characteristics including 1,000 grain weight and grain size (length, width and thickness), PHS tolerance conducted by the mist spray in the humid chamber (PHS-MS) and germination index (GI), and Agronomic traits including heading date, maturing date, culm length, awn length and the number of grain/spike, were significantly influence by genotype, year and the interaction between year and genotype, except in spike length, the number of spike/m 2 and test weight. PHS tolerance and GI were significantly correlated with 1,000-grain weight (r = 0.618, and r = 0.528, respectively) and length, width and thickness of grain, although no significant relationship between agronomic traits and PHS tolerance was found in Korean wheat cultivars. PHS-MS also showed positively correlated with GI value (r = 0.770, P < 0.001). White grain cultivars showed higher PHS-MS and GI values (61.86% and 0.58, respectively) than red grain cultivars (11.89% and 0.18, respectively). White grain cultivars also showed higher values in length, width and thickness of grain than red grain cultivars. Among red grain cultivars, Alchan, Goso, Suan and Sukang showed lower values in both PHS-MS and GI (< 2.63% and < 0.05, respectively) and these cultivars could be used to improve PHS tolerance in Korean wheat breeding programs.
