Inbred corn line cb20

A method for producing inbred corn line AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20, wherein a representative sample of seed of said line was deposited under ATCC Accession No. PTA-______, wherein the method comprises:

• a) planting a collection of seeds comprising seed of a hybrid, one of whose parents is inbred line AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20, said collection also comprising seed of said inbred;
• b) growing plants from said collection of seeds;
• c) identifying the plants having the physiological and morphological characteristics of inbred corn line AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20 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 AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20.

A method of introducing one or more desired traits into inbred corn line AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20 wherein the method comprises:

• a) crossing the inbred line AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC106, BC137, or CB20 plants grown from the inbred line AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20 seed, wherein a representative sample of seed of said line was deposited under ATCC Accession No. PTA-______, 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 AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20 plants to produce backcross progeny plants;
• d) selecting for backcross progeny plants that have the one or more desired traits and physiological and morphological characteristics of inbred corn line AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20, wherein a representative sample of seed of said line was deposited under ATCC Accession No. ______, 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 of the physiological and morphological characteristics of inbred corn line AB8, AB18, AB19, BB84, BB85, BB95, BB98, BB201, BC137, or CB20 as listed in Table 1A to Table 1S.
