Plant breeding of rice emphasizes improvement in yield, disease resistance, and milling quality. Numerous other traits (e.g., bran carotenoids) that historically have not been selected for could provide added value in expanding niche markets, as well as be useful tools for understanding the genetic control of these traits. Residual heterozygosity is present in many rice cultivars; therefore, it is possible to select for different alleles within an existing cultivar. By identifying and using cultivars with high levels of variability for a trait, we were able to develop separate lines from single cultivars that showed high and low levels of that trait. The rice cultivar RU9101001 and the warm- and cold-sprouting lines that were derived from it were used to demonstrate that residual heterozygosity was present within a cultivar and that the original heterozygosity was separated in the derived lines. Rice simple sequence repeat markers were heterozygous in the parent RU9101001 cultivar, but the cold-sprouting lines were homozygous for one set of alleles and the warm-sprouting lines were homozygous for the other set. Through detailed phenotypic screening, we developed lines that exhibited low and high levels of the following traits in the specified cultivars: cold-sprouting from RU9101001 and Bonnet 73, postharvest yellowing from Tominishiki, early tillering from Hei Jaio and Tominishiki, and bran carotenoid levels from Spring. If variability exists in a cultivar, then utilization of residual heterozygosity may provide a quicker and more efficient means to develop lines with special characteristics using cultivars that are already agronomically valuable or to develop near isogenic lines for genetic and biochemical investigations.

“…CI9695 has the pedigree CI9453/CI9187//‘Bluebonnet 50’. Rexoro and Bluebonnet 50 were described by Johnston (1958) Starbonnet is a long grain cultivar described by Johnston et al (1968) LaGrue is a high‐yielding long‐grain rice described by Moldenhauer et al (1994) The experimental designation for early evaluation of Francis was STG96L05–077, starting with a bulk of F 6 seed from the 1996 panicle row L05–077. Francis was tested in the Arkansas Rice Performance Trials (ARPT) and the Cooperative Uniform Regional Rice Nursery (URRN) during 1999–2001 as entry RU9901081 (RU number indicates Cooperative Uniform Regional Rice Nursery; 99 indicates year entered; 01 indicates Stuttgart, AR; and 081 indicates entry number).…”

“…This line is extremely early and has cold tolerance during germination and early growth stages. Vegold was described by Johnston and Adair (1965) Bonnet 73 and Starbonnet were described by Johnston et al (1973, and 1968, respectively). PI 265116 is Zeawchanica Karatalski a very early growth duration line from Hungary which heads in approximately 48 d in Arkansas.…”
