Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
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.
Claim 2
Dependent Claim
