Other claims from this paper (11)
- Observation Forty-two RAPD primers were polymorphic between the parents.
- Observation The 42 primers generated 122 reproducible bands in 55 BC F 1 plants.
- Method / resource The map contained 102 markers on 22 linkage groups.
- Method / resource The linkage map spanned approximately 1195.2 cM.
- Observation Most markers did not deviate from the expected 1:1 segregation ratio.
- Observation Some terminal markers had significant segregation distortion.
- Observation Twenty RAPDs remained unmapped.
- Observation Nine unmapped RAPDs had highly distorted segregation ratios.
- Method / resource The authors infer the first map gives good genome coverage.
- Association Predominantly normal marker segregation suggests significant homology between the two genomes.
- Recommendation The authors suggest useful C. ecuadorensis traits could be introgressed into C. maxima.
