Rice cultivar R031001

A method of introducing a desired trait into rice inbred line R031001 comprising:

• (a) crossing R031001 plants grown from R031001 seed, representative seed of which has been deposited under ATCC Accession No. PTA-6795, with plants of another rice line that comprise a desired trait to produce F1 progeny plants, wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance, disease resistance and increased or decreased amylose starch production;
• (b) selecting F1 progeny plants that have the desired trait to produce selected F1 progeny plants;
• (c) crossing the selected progeny plants with the R031001 plants to produce backcross progeny plants;
• (d) selecting for backcross progeny plants that have the desired trait and physiological and morphological characteristics of rice inbred line R031001 listed in Table 1 to produce selected backcross progeny plants;
• and
• (e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of rice inbred line R031001 listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions.

A method of modifying fatty acid metabolism, modifying phytic acid metabolism or modifying carbohydrate metabolism into rice inbred line R031001 comprising:

• (a) crossing R031001 plants grown from R031001 seed, representative seed of which has been deposited under ATCC Accession No. PTA-6795, with plants of another rice line that comprise a nucleic acid molecule encoding an enzyme selected from the group consisting of phytase, stearyl-ACP desaturase, fructosyltransferase, levansucrase, alpha-amylase, invertase and starch branching enzyme;
• (b) selecting F1 progeny plants that have said nucleic acid molecule to produce selected F1 progeny plants;
• (c) crossing the selected progeny plants with the R031001 plants to produce backcross progeny plants;
• (d) selecting for backcross progeny plants that have said nucleic acid molecule and physiological and morphological characteristics of rice inbred line R031001 listed in Table 1 to produce selected backcross progeny plants;
• and
• (e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny plants that comprise said nucleic acid molecule and have all of the physiological and morphological characteristics of rice inbred line R031001 listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions.
