To Maize Geneticists :-

This maize letter contains a list of new genetic stocks, as well as a considerable number of news items. Several new stocks were listed in the last maize letter - they will not be repeated here. The response of the various investigators to the request for material has, as heretofore, been gratifying and has made possible this series of maize letters.

The new stocks have been grouped together as follows:

From Singleton

Chromosome 4 stocks:

1.	+ su Tu	x wl su tu.
	wl + +	x wl su tu.

2.	Ts₅ + su	x ts wl su.
	+ wl +	x ts wl su.

3.	su +
	+ sp

4.	su sp

5.	su lo

6.	su +

7. su Ts₅.

8.	wl su +	F₂.
	+ su gl₃	F₂.

9.	Ts₅ + su	F₂.
	+ wl su	F₂.

10.	wl + tu	x wl su Tu.
	wl su tu	x wl su Tu.

Stocks other than chromosome 4:

Chromosome 1. P ts₂ f₁ bm₂.

Chromosome 2.	v₄	ts₁	gl₂ lg₁ and lg₁ gl₂ v₄ A C r^g Y Su.
		+

Chromosome 5. v₂ bm₁ pr.

Chromosome 7. gl₁ v₅ seg. ra₁ and gl₁ ij Y Su.

From Burnham

Chromosome 1. f₁ an bm₂.

Chromosome 1. P f₁ bm₂ and p f₁ bm₂.

Chromosome 2. lg₁ gl₂ b v₄ which does not carry Pl or r^g, it is probably r^r.

From Randolph

10-chromosome tester stocks:

1. A₁-na-cr C R^g pr in su y-pl b-lg₁ j bm₂.

2. A₁-Na na (Cr cr)? C R^g pr in su y-pl j b-lg₁ bm₂-	ts₂
	Ts₂ ts₂.

3. A₁ c R^g-g₁ pr In-Bn su y-pl b-lg j bm₂.

4. A₁-cr c R^g-G₁g₁ pr In (in)? - Bn Su su y-pl b-lg₁ j bm₂.

5. A₁-D (d)? c R^g-g₁ pr In (in)? - Bn Su Su and Su su y-pl b-lg₁ j bm₂ - Ts₂ ts₂.

6. A₁-D (d)? c R^g-g₁ pr In-Bn su y-pl b-lg j bm₂ P^vv.

From Jenkins

Chromosome 5:

A₁ C R A₂a₂-bt₁-bv-pr.
A₁ A₂ C R bt₁-bv-pr.
A₁ C R a₂-bt₁-bv-pr.
A₁ A₂ C R bv-pr-v₂.
A₁ A₂ C R bt₁-bv-pr.

Jenkins will have pollen this summer from:

a₂-bt₁-bv-pr-v₂ plants.

Chromosome 4:
