1. Lg₃ (dominant liguless) is in chromosome 3 as shown by the following summary of data from six small cultures:

Genes	Phase	XY	Xy	xY	xy	Total
Rg Lg₃	RB	3	138	124	0	265	(p = .011)

A greater portion of the ligule is present in Lg₃ plants than in either lg₁ or lg₂ plants. But for the characteristic "liguless" appearance of the plant as a whole the character might more appropriately be called "defective ligule". Classification (except for seedlings), viability, and fertility (except perhaps for homozygotes) are satisfactory.

A test for allelism with lg₂ and three-point tests are being made.
