Abstract: In order to screen for high-yield, high-quality, and early maturing potato strains, a comprehensive evaluation was conducted on the growth period, field plant traits, tuber traits, starch content, and yield of 9 potato strains self cultivated by Keshan Branch of Heilongjiang Academy of Agricultural Sciences. The results showed that two early maturing lines with a growth period of 77-78 days and a semi upright plant type were selected from 9 strains. Ke 20215-14 had purple corollas, long elliptical tubers, red skin and yellow flesh, and shallow bud eyes. Its yield was 3 393.36 kg·（667 m~2）^-1, and its starch content was 15.22 g·（100 g）^-1. Ke 20215-122 had white corollas, elliptical tubers, yellow skin and flesh, and moderate bud eyes. Its yield was 3 491.75 kg·（667 m~2）^-1, with a starch content of 9.81 g·（100 g）^-1. Ke 202015-76, Ke 202015-38, Ke 202015-69, and Ke 202015-135 had good comprehensive traits, and they were recommended to enter the screening experiment for early and medium maturing strains in the next year.The remaining 3 strains were eliminated in subsequent experiments due to their yield or ripening period not meeting the requirements.
