In Malaysia, stresses like high rainfall and high temperature have a strong influence on wheat growth and yield. These stresses are known to cause stunted plant growth, reduced tillers and accelerated development resulting in small heads, shriveled grains and low yields. The genetic variability and association analysis indicated that rapid grain filling, number of fertile tillers, grain per spike, 1000 grain-weight, Helminthosporium leaf blight and aphids resistance may serve as valuable selection criteria for wheat germplasm accessions in Malaysia. Also, variation in different agronomic characters in bench-mark study and pot experiments indicated that good management might offset the harmful effects of high temperature and high rainfall. Based on the screening results, five bread wheat and two triticale lines were suggested for future exploitation.
