Inbred maize line PH4RD

A process of producing a conversion of maize inbred variety PH4RD comprising at least one new trait, the process comprising:

• (a) crossing a plant of maize inbred variety PH4RD, representative seed of which has been deposited under ATCC Accession Number PTA-7523, with a plant of another maize variety that comprises at least one new trait to produce progeny seed;
• (b) harvesting and planting the progeny seed to produce at least one progeny plant of a subsequent generation, said progeny plant comprising the at least one new trait;
• (c) crossing the progeny plant with a plant of maize inbred variety PH4RD to produce backcross progeny seed;
• (d) harvesting and planting the backcross progeny seed to produce at least one backcross progeny plant;
• and
• (e) repeating steps (c) and (d) for at least three additional generations to produce a converted plant of inbred variety PH4RD, wherein the converted plant of inbred variety PH4RD comprises the at least one new trait and otherwise has all of the morphological and physiological characteristics of inbred variety PH4RD listed in Table 1 as determined at the 5% significance level when grown under the same environmental conditions.
