TULIP BREEDING BASED ON NON-REDUCED POLLENGRAIN TECHNIQUE |
| Author: | B. Andreasen |
| Abstract:
Unreduced pollengrains have been produced by the method of bulb treatment with nitrous oxide. Chromosome counts in pollen tubes were carried out for a number of cultivars. The pollengrain produced had a variable percentage of unreduced chromosomes and were used to pollinate diploid cultivars. The hybrids were not analysed for ploidy, but a general analysis of the characters of the seed plants was carried out and the results will be shown. | |
