چکیده

ILD Gossypium anomalum Wawrs. and Peyr. among Gossypium species whas anomalous petal spot inheritance. Its petal spot involves two independently inherited genes; a ghost spot gene interacts with a spotless gene making a large anthocyanin area at the base of a petal (SILOW 1941). In the two cultivated Asiatic diploid species red petal spot involves three closely linked genesmargin. ghost spot, and spotless (Yu and CHANG 1948). In amphidiploid G. hirsutum L. and G. barbadense L. red petal spot acts as a unit. Ghost spot of G. anomalum is allelic with ghost spot of G. arboreum L. Ghost spot is detected as a white spot on a yellow petal but is invisible on a white petal ( SILOW 1941 ) . Red petal spot of G. arboreum is allelic in amphidiploid G. hirsutum with red petal spot (HARLAND 1935). The spotless gene of G. anomalum is a flush expression on petal margins (SILOW 1941) and phenotypically it resembles the spotless allele of G. arboreum. Both produce red petal spot through interaction with ghost spot of either species. The similarity of flush of the G. anomalum spotless and red petal-margin of G. hirsutum RI was discussed by SILOW (194l), but sterility of his hybrids prevented him from determining allelic relationships. This paper is concerned with petal spot genes of G. anomalum in amphidiploid G. hirsutum. Anomalous placement of the ghost spot gene and associated disturbance in lint-color segregation are reported. Methods of transferring these genes are compared.
