Table (6) presented correlation between the degree of resistance and other characteristics. The results indicated to positive relationship for resistance degree with fruit set, fruit number and yield. The estimates values were 0.949, 0.749 and 0.609 and they were highly significant. It can explained resistant plants performed well against early blight and had a reasonable yield while the susceptible infected plants suffered in foliage and in all parts negatively reflected in loss in yield and yield components from the beginning as they had a reduction in fruit set, fruit number and yield under greenhouse conditions. Results in Table (6) and figure (1) revealed a positive relationship between fruit set and fruit number and it was highly significant 0.811, while it was 0.521 with yield. Meantime, fruit diameter showed positive correlation with locules, fruit weight and yield but, there was a negative relationship with total soluble solids. Data also detected that T.S.S. had negative correlation with most of measurements such as resistance, fruit set, fruit flesh thickness, fruit weight and yield. This characteristic needs more studies in breeding programs to select plants which have high degree of resistance to early blight and also carry genes for total soluble solids desirable characters of quality. These results indicated that NCEBR-6 is a resistance source to early blight disease.
