Details

Plants of stock 1-122, F1, are wild type, for anthocyaninless, anl/ANL, yellow-green, YGR1/ygr1, and male sterile, mst2/MST2, are 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, Ysc1.

Stock 1-122, F1 is from the cross of stock 1-107 as the maternal parent expressing Anl, Hir (1), Pan (6) with stock 1-120 as the paternal parent expressing Ygr1, Hir(5), Pan (8). Sib mating 1-122 produces 1-123, exhibiting F2 dihybrid segregation patterns for Anl and Ygr1. Mass crossing 1-122 to 1-105, Anl, Ygr1, Mst2, produces 1-128, yielding testcross segregation patterns.

When grown together, stock 1-107 (or 1-108) as a maternal parent expressing, Anl, Hir (1), and stock 1-120, as paternal parent expressing, Ygr1, Pan (8), Hir (5), with stocks 1-122, F1 and stock 1-123, F2 are useful in illustrating dominant and recessive expression, segregation, assortment and recombination.

1-122 can also 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, Ygr1 and Mst2.
