F1 Anthocyaninless

Plants of stock 1-124, F1, are wild type for anthocyaninless, anl/ANL, and male sterile, mst2/MST2, in a genetic background for high expression of purple anthocyanin, Pan (6/8), and are segregating for hair numbers on specified parts, Hir (1/5). Seed color is yellow. 


Stock 1-124, F1 is from the cross of stock 1-107 as the maternal parent expressing Anl, Hir (1), Pan (6) with stock x 1-67 as the paternal parent expressing Hir (5), Pan (8). Sib mating 1-124 produces 1-125, exhibiting F2 monohybrid segregation patterns for Anl and Mst2. Mass crossing 1-124 to 1-107, Anl, Mst2, produces 1-152, yielding testcross segregation patterns for Anl and Mst2.

When grown together, stock 1-107 (or 1-108) as a maternal parent expressing, Anl, Hir (1), and stock 1-67, as paternal parent expressing, Pan (8), Hir (5), with stocks 1-122, F1 and 1-123, F2 are useful in illustrating dominant and recessive expression, assortment and segregation.

Stock 1-124 can be used for the studies combining the inheritance patterns of the quantitatively variable traits, hair number, Hir, and intensity of purple anthocyanin, Pan, while following the inheritance patterns of the discrete traits, Anl, and Mst2.
