| Abstract: | In order to select high quality and high yielding varieties for practical production and promotion, 24 potato high generation strains were investigated and determined for their agronomic, physiological and biochemical indicators and yield traits. A correlation analysis was conducted on five indexes, namely chlorophyll relative value, leaf water loss rate, isolated leaf conductivity, plant height and yield, and a comprehensive evaluation of their drought resistance was carried out using the affiliation function method. The results showed that the early fresh food lines BF1111.8 and medium early processing lines BF113.31 and BF113.13 with excellent agronomic traits; the very strong drought resistance materials BF1111.8, BF1245.2 and BF0750.43; and the excellent overall traits materials BF1111.8 were selected. |
