To Corn Geneticists :-

Enclosed with this is a report of the meeting of corn geneticists held at Ithaca at the time of the Genetics Congress and a report of a committee provided for at that meeting.

In accordance with the action taken by the whole group and by the committee, it is requested that, as soon as convenient, you send to the undersigned a small quantity of seed of any stocks which you think may be useful to other workers now or which should be maintained for future use. As these lots of seed are received, a record of them will be made and later sent to all of you so that you may know what is available. As an illustration of combinations of genes such as should be available for distribution, a list of types now in our possession at Cornell is given below. You should not fail to send material even though it duplicates stocks in this list.

1. lg-gl₂-b-v₄

2. Bn-ra-v₅

3. Bn-gl1-v₅

4. y-Pl-al

5. a₁ P sh wx lg f₁

6. A B Pl lg sh wx y

7. lg g a₁-na-ts

8. p-(Ts₂ ts₂)-(Ff)-(Br br)-an

9. A₁-na-cr gl₁-v₅ ts₂-f₁ Y-Pl

10. a₁ j B-lg Y-Pl C r^r pr

11. P-br-f-an

12. P-br-f-brn₂

A limited supply of trisomic seed is available for the b-lg, a-na, pr-v₂, Y-Pl, ra-gl₁, j, c-wx, and r-g linkage groups. We shall be glad to supply samples of this seed to the different individuals charged with the responsibility of the various groups. If the demand is not too great we shall try to supply all requests for trisomic seed.

If your work requires some unusual set-up or if you want better material of certain types than you now have, please indicate your needs at once. These requests will then be circulated from this office. As an illustration of what is in mind here, Emerson wants an early maturing stock involving green-striped. He also desires the combination adherent-anther ear.
