## Abstract

Inbred corn line designated BB202 is disclosed. The invention relates to the seeds of inbred corn line BB202, to the plants and plant parts of inbred corn line BB202 and to methods for producing a corn plant, either inbred or hybrid, by crossing inbred corn line BB202 with itself or another corn line. The invention also relates to products produced from the seeds, plants, or parts thereof, of inbred corn line BB202 and/or of the hybrids produced using the inbred as a parent. The invention further relates to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other inbred corn lines derived from inbred corn line BB202.

b) growing plants from said collection of seeds;
c) identifying the plants having the physiological and morphological characteristics of inbred corn line BB202 as inbred parent plants;
d) controlling pollination of said inbred parent plants in a manner which preserves the homozygosity of said inbred parent plant; and
e) harvesting the resultant seed and thereby producing an inbred corn line having all of the physiological and morphological characteristics of inbred corn line BB202.

### Claim 10 (depends on 9)

The method of claim 9 wherein step (c) comprises identifying plants with decreased vigor compared to the other plants grown from the collection of seeds.

### Claim 11 (depends on 2)

A method for producing a corn plant that contains in its genetic material one or more transgenes, wherein the method comprises crossing the corn plant of claim 2 with either a second plant of another corn line which contains a transgene or a transformed corn plant of the inbred corn line BB202, so that the genetic material of the progeny plant that results from the cross contains the transgene(s) operably linked to a regulatory element and wherein the transgene is selected from the group consisting of male sterility, male fertility, herbicide resistance, insect resistance, disease resistance, water stress tolerance, and increased digestibility.

### Claim 12 (depends on 11)

A corn plant, or a part thereof, produced by the method of claim 11.

### Claim 13 (depends on 12)

The corn plant of claim 12, wherein the transgene confers resistance to an herbicide selected from the group consisting of imidazolinone, sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine and benzonitrile.

### Claim 14 (depends on 12)

The corn plant of claim 12, wherein the transgene encodes a Bacillus thuringiensis protein.
