In verband met de onderzoekingen van Lock vestigen wij er de 
aandacht op dat een roode pigmenteering in onze proeven noch 
in de zaadhuid, noch in de bladoksels of bloemkroon is opge- 
treden. De factor, die volgens dezen onderzoeker rood anthocyaan 
in paars verandert, zou dus in alle behandelde soorten aan- 

wezig zijn. 

Summary. 
Several crosses were made between some races of peas fre- 
| quently grown in Holland for culinary purposes. Of these „Blauw- 
| peul” is a large brown seeded pea with indent seeds. It has 
pigment in its testa, but does not possess the factor for spots. 
„Krombek”, a pea with curved pods, yellow cotyledons and 
pigmentless testa possesses this factor for spots; thus the cross 
Krombek x Blauwpeul gives spotted seeds in the Fy. 
„Kroonerwt”’, a green pea with big globular seeds has also the 
spot factor, but American Wonder, green with wrinkled seeds, 
has not. „Low Cape Capucin” has small spotted seeds of indent 
shape. Crossed with American Wonder it gives rise to all kinds 
of peas, but a remarkable fact in all crosses mentioned is, that 
where pigment is present in the testa, the form of the seeds always 
is indent. Pure wrinkled and globular seeds have colourless testa. 
The factor for indent is hyperstatic over globular.
