The correlation between important farm indicators in potato (Solanum tuberosum L.), eggplant (Solanum melongena L.) samples

The article indicates the correlation relations between different important farm indicators of the potato and eggplant sort samples of different geographical origin. The leaf surface area, the amount of the chlorophyll in the leaves, the dry biomass and dry substance were determined in the potato and eggplant sort samples. The correlation relations between various important farm indicators of 20 potato (Solanum tuberosum L.) and 59 eggplant (Solanum melongena L.) collection samples cultivated in the Absheron auxiliary experimental farm of the Vegetable Scientific-Research Institute were studied and it was shown that there are exact relations which are the dense according to the Cheddock scale at the p≥0.05% level between these indicators. In potato, the relations between leaf surface area–PP (0.922), leaf surface area–chlorophyll (0.911), leaf surface area–productivity (0.672), chlorophyll–PP (0.872), PP–productivity (0.611), chlorophyll-SSDL (-0.812), PP-SSDL (-0.818), leaf surface area-SSDL (-0.829), and in eggplant, (0.442-0.838) - leaf surface area-PP (0.838), leafsurface area-wet biomass (0.672), leaf surface area-dry biomass (0.612), PP-productivity (0.465), PP-wet biomass (0.455) and leaf surface area-productivity (0.442) can be belonged such relations (0.611-0.922) that can be used successfully in the selection which will be carried out in future according to the productivity, quality and adaptability.
