Spot blotch (SB), caused by Bipolaris sorokiniana, is one of the most destructive diseases of barley (Hordeum vulgare) especially in tropical humid and semi-humid barley growing areas of the world. Agro-phenological traits; plant height (PHT) and days to 50% heading (DTH) are important in barley life cycle and development of superior cultivars. In the present study, association of SB with agro-phenological traits were investigated in 124 germplasm lines and two F3 and F4 populations derived from the two different crosses under SB prone environment. Results showed significant variation for PHT, DTH and SB resistance in the germplasm, parental lines and its F3 and F4 populations. Transgressive segregates were observed among the lines for PHT, DTH and SB severity. The t-test's statistical significance of homozygous resistant and homozygous susceptible families selected from F3 and F4 populations of both crosses indicates that the differences for mean values of PHT and DTH is not significant however these families showed a wide range of PHT and DTH. The correlation coefficients for AUDPC versus PHT and DTH were weak, i.e., 0.00 to 0.22 indicating that spot blotch resistance was independent of PHT and DTH in germplasm and segregating generations. The basic information generated in present study could help the breeders for development of SB resistant varieties for different geographic regions and different uses
