e0“Overall frequencies of big pollen (BP) and dyad formation were substantially higher in E1 in both years.”
e1“Ten genotypes of Solanum phureja Juz. and Buk. producing 2n pollen via fused (FS) and tripolar (TPS) spindles at the second meiotic division were grown in 2 consecutive years at a cool field site (E1, 8–22 °C)”

Other claims from this paper (9)
- Association Big pollen frequency was substantially higher at the cool field site in both years.
- Observation Stable standard 154-1 had near-complete dyad expression in the cool site, with no bud below 99%.
- Observation Genotype 413 produced 93–99% mean dyad frequency at the cool site.
- Observation Genotype 414 produced 93–99% mean dyad frequency at the cool site.
- Observation Genotype 416 produced 93–99% mean dyad frequency at the cool site.
- Observation Genotype 417 produced 93–99% mean dyad frequency at the cool site.
- Association Variable genotypes had higher dyad frequencies at the cool site but remained variable, with within-collection disparities up to 79%.
- Observation Stable genotypes consistently showed 86–99% dyad frequency on all four dates.
- Observation Variable genotypes showed substantially lower and more variable dyad frequencies.
