9. The method of claim 8 wherein step (c) comprises identifying plants with decreased vigor compared to the other plants grown from the collection of seeds.
10. 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 ML9, 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.
11. A corn plant, or a part thereof, produced by the method of claim 10 .
12. The corn plant of claim 11 , wherein the transgene confers resistance to an herbicide selected from the group consisting of imidazolinone, sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine and benzonitrile.
13. The corn plant of claim 11 , wherein the transgene encodes a Bacillus thuringiensis protein.
14. The corn plant of claim 11 , wherein the transgene confers disease resistance.
15. The corn plant of claim 11 , wherein the transgene confers water stress tolerance.
16. The corn plant of claim 11 , where in the transgene confers increased digestibility.
17. A method for producing a hybrid corn seed wherein the method comprises crossing the plant of claim 11 with a different corn plant and harvesting the resultant hybrid corn seed.
18. A method of producing a corn plant with waxy starch or increased amylose starch wherein the method comprises transforming the corn plant of claim 2 with a transgene that modifies waxy starch or amylose starch metabolism, thereby producing a corn plant with waxy starch or increased amylose starch.
19. A corn plant produced by the method of claim 18 .
20. A method of introducing a desired trait into inbred corn line ML9 wherein the method comprises:
a) crossing the inbred line ML9 plants grown from the inbred line ML9 seed, wherein a representative sample of seed of said line was deposited under ATCC Accession No. PTA-120137, with plants of another corn line that comprise one or more desired trait to produce progeny plants, wherein the one or more desired trait is selected from the group consisting of male sterility, male fertility, herbicide resistance, insect resistance, disease resistance, waxy starch, water stress tolerance, increased amylose starch and increased digestibility;
b) selecting progeny plants that have the one or more desired trait to produce selected progeny plants;
c) crossing the selected progeny plants with the inbred corn line ML9 plants to produce backcross progeny plants;
d) selecting for backcross progeny plants that have the one or more desired trait and physiological and morphological characteristics of inbred corn line ML9 listed in Table 1 to produce selected backcross progeny plants; and
e) repeating steps (c) and (d) one or more times in succession to produce selected second or higher backcross progeny plants that comprise the desired one or more traits and all the physiological and morphological characteristics of inbred corn line ML9 as listed in Table 1.
21. A corn plant produced by the method of claim 20 , wherein the plant has the one or more desired trait and all of the physiological and morphological characteristics of inbred corn line ML9 as listed in Table 1.
