Abstract

A soybean variety which is a high yielder and resistant to iron deficiency chlorosis.

Claims

1. A novel process to produce the seeds of a soybean variety resistant to iron deficiency chlorosis comprising the steps of:

(a) crossing plants grown from seeds of Beeson and Corsoy;

(b) developing a pure plant line from the seeds produced in (a) and crossing plants grown from said line with plants grown from seeds of Hodgson;

(c) developing a pure plant variety from the seeds produced in (b), said variety being selected for those resistant to iron deficiency chlorosis; and

(d) harvesting the seeds of said pure resistant plant variety.

2. The process of claim 1 wherein a pure plant variety is first developed from the seeds produced in (b) and said pure plant variety is subsequently subjected to selection for those resistant to iron deficiency chlorosis.

3. The process of claim 1 wherein a plant line selected for resistance to iron deficiency chlorosis is first developed from the seeds produced in (b) and said resistant plant line is subsequently developed into a pure plant variety.

4. The process of claim 1 wherein Hodgson is employed as the female in step (b).

5. The process of claim 1 wherein said selection in (c) is performed by growing plants on calcareous soil and selecting those that are green at an early trifoliate growth stage.

6. Seeds produced according to the process of claim 1.

7. Novel soybean variety CX174.
