The production of progeny by sesquidiploids was reported in TGC report No. 4. The 2n chromosome numbers of the 11 plants were follows: one plant 26, one plant 30, one plant 31, 4 plants 32, 3 plants 33, and one plant 34. In the greenhouse all of these plants were quite vigorous. An additional plant was a very slow grower and no satisfactory chromosome counts have been obtained. The percentage of pollen stainable with acetocarmine ranged from 0 (2n=30) to a high of 60 (2n=32). No seeds were set by selfing, intercrossing or crossing with L. esculentum. Two plants produced fruits without hand pollination. All of these fruits were seedless. In the field all plants were very weak and several died during the summer. In the field four additional plants produced fruits from open pollination. The average fruit size ranged from 1.5 grams to 4.2 grams. The average number of seed per fruit ranged from 0.05 to 2.61. Viability of the seeds has not been determined. Fruit color varied from very pale yellow-green to pale orange.
