There was a general reduction in dry matter distribution in tubers and roots in all the genotypes under heat stressed condition. The heat tolerant genotypes, however, partitioned more dry matter towards tuber and roots compared to susceptible ones. Also the proportional increase in mean internode length in heat stressed plants was more in tolerant genotypes as compared to susceptible ones.
