Inbred corn line MN40

A method for producing inbred corn line MN40, wherein a representative sample of seed of said line was deposited under NCMA Accession No. 202404001, the method comprising:

• (a) planting a collection of seeds comprising seed of a hybrid, one of whose parents is inbred corn line MN40, the collection also comprising seed of the inbred corn line;
• (b) growing plants from the collection of seeds;
• (c) identifying the plants having all of the physiological and morphological characteristics of inbred corn line MN40 as inbred parent plants;
• (d) controlling pollination of the inbred parent plants in a manner that preserves the homozygosity of the inbred parent plants;
• 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 MN40.

A method of introducing one or more desired traits into inbred corn line MN40, the method comprising:

• (a) crossing inbred corn line MN40 plants grown from inbred corn line MN40 seeds, wherein a representative sample of seed of the line was deposited under NCMA Accession No. 202404001, with plants of another corn line that comprise one or more desired traits to produce progeny plants, wherein the one or more desired traits are 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 traits to produce selected progeny plants;
• (c) crossing the selected progeny plants with the inbred corn line MN40 plants to produce backcross progeny plants;
• (d) selecting for backcross progeny plants that have the one or more desired traits 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 one or more desired traits and all of the physiological and morphological characteristics of inbred corn line MN40.
