Other claims from this paper (9)
- Observation Significant correlations were found among the drought tolerance coefficients of the 24 measured potato indicators.
- Observation Principal component analysis reduced the 24 potato indicators to six components explaining 86.38% of cumulative variance.
- Observation D-value cluster analysis classified 31 potato germplasm resources into five drought tolerance categories.
- Observation Fresh and dry above-ground biomass are suitable objective criteria for judging potato drought tolerance in mid-to-late growth stages.
- Observation Fresh and dry below-ground biomass are suitable objective criteria for judging potato drought tolerance in mid-to-late growth stages.
- Observation Chlorophyll content and relative chlorophyll content are suitable objective criteria for judging potato drought tolerance in mid-to-late growth stages.
- Observation Net photosynthetic rate, stomatal conductance and superoxide dismutase activity are suitable objective criteria for judging potato drought tolerance in mid-to-late growth stages.
- Observation Number of large tubers per plant, fresh tuber weight per plant and plot yield are suitable objective criteria for judging potato drought tolerance in mid-to-late growth stages.
- Observation Long 10, D1595-7, Lin 18, Tong 31 and D16105-14 are the strong drought-tolerant potato materials.
