Abstract

In a study to find out the reaction of certain tomato genotypes to early blight, it was found that the genotypes IHR 1939, IHR 1816, IHR 1954 and IHR 1968 showed resistance at both seedling and adult plant stages. IHR 1817 had relatively low levels of resistance at seedling stage. Of these five resistant lines, IHR 1939 derived from L. pimpinellifolium displayed higher level of early blight resistance at both seedling (42.91 per cent CDI) and adult (37.86 per cent CDI) plant stages.
