Inheritance of brown pigmentation of the leaves was studied in 11 crosses involving 9
genotypes with pigmented and 4 with nonpigmented (green) leaves, which were crossed
in direct (6 crosses) and reciprocal (4 crosses) combinations. Analysis of 4468 F2plants under
field conditions revealed perfect monogenic segregation into 3 brown: 1 green ratio. It was
a rare case of absence of deviations from expected numbers in F:z, resulting into X2= O. The
development of brown pigmentation is, thus, controlled by a single dominant gene and its
recessive condition results in formation of normal green leaves through the entire plant
life. The gene symbol Bl (brown leaf) is proposed for this trait. The pattern of
stage-dependent synthesis of brown pigment and its disappearance is described.
