White clover (Trifolium repens L) variants with extremely large inflorescences, and their seed production

Single crosses were carried out in 1981, but for several reasons cultivar formation did not occur. In spite of this, the introduced germplasm available after mutation breeding is not inferior in the case of free pollination to the oldtimer single crosses. For some proportion the introduced germplasm is even better. The seed number per flowerhead is unusually high: (x) over bar=250 550. The number of seeds per flower may be as high as 3.6-1.7, while this value was only 1-1.9 for single crosses. In the case of one Trifolium repens forma hollandicum flower the petiole grew to a length of 80 cm. We can expect to breed good single or double crosses.
