Oppositional Alleles Causing Cross-Incompatibility in Trifolium Repens.
N SEVERAL species in which cross-incompatibility is determined by I multiple oppositional alleles, different types of tests have shown that these series of alleles are very extensive. The test yielding the most decisive results and involving the fewest crosses consists of making all possible reciprocal combinations (that is, diallel crosses) between plants which have one S factor in common. Thi...
متن کاملMutations of Self-Incompatibility Alleles in Trifolium Pratense and T. Repens.
HE existence of several allelomorphs at the S locus has been demonstrated in T Nicotiana spp. (EAST and YARNELL 1929), Veronica syriaca (LEHMANN 1926), Antirrhinum glutinosum ( GRUBER 1932), Trifolium pfatense (WILLIAMS 1939; and WILLIAMS and WILLIAMS 1947), Oenothera organensis (EMERSON 1939, 1940) and Trifolium repens (ATWOOD 1944). In Trifolium pratense, BATEMAN (1947) calculated that the nu...
متن کاملIncompatibility in Autotetraploid Trifolium Repens L. I. Competition and Self-Compatibility.
ELF-INCOMPATIBILITY is the inability of a plant producing functional male and female gametes to set seed upon self-pollination. The best known genetic system effecting incompatibility in plants is that in which a single series of oppositional alleles governs pollen-tube growth, with pollen behavior under autonomous, or gametophytic, genetic control (EAST and MANCELSDORF 1926). Self-incompatibil...
متن کاملIncompatibility in Autotetraploid Trifolium Pratense.
RIFOLI U M pratense L. is a highly self-incompatible species. An oppositional Tsystem of incompatibility has been established in this species by WILLIAMS and SILOW (1933). Artificially induced autopolyploids have been produced by LEVAN (1948) and FRANDSEN (1948) and selections have been carried out for several generations to improve their fertility. But no work has been done to study the effect...
متن کاملOppositional Allelism in Diploid and Autotetraploid Trifolium Hybridum L.
HE selfand cross-incompatibilities of a number of obligately cross-polliT nated species of flowering plants are genetically determined by series of multiple oppositional alleles. The oppositional or personate incompatibility system was first described, with substantiating data, by EAST and MANGELSDORF (1925) for Nicotiana species. The existence of oppositional alleles has been subsequently demo...
