Rice cultivar 'Spring'

A method of introducing a desired trait into rice cultivar ‘Spring’ wherein the method comprises:

• (a) crossing a ‘Spring’ plant, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-______, with a plant of another rice cultivar that comprises a desired trait to produce progeny plants wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance, modified fatty acid metabolism, modified carbohydrate metabolism and resistance to bacterial disease, fungal disease or viral disease;
• (b) selecting one or more progeny plants that have the desired trait to produce selected progeny plants;
• (c) crossing the selected progeny plants with the ‘Spring’ plants to produce backcross progeny plants;
• (d) selecting for backcross progeny plants that have the desired trait and the physiological and morphological characteristics of rice cultivar ‘Spring’ to produce selected backcross progeny plants;
• and
• (e) repeating steps (c) and (d) one time to produce selected third or higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of rice cultivar ‘Spring’ as listed in Table 1.
