Introduction of a High-quality Tri-lineage Sterile Line Rice, Taifeng A

Taifeng A was a high-quality, tri-lineage sterile line of hybrid rice originally bred by the Rice Research Institute, Guangdong Academy of Agricultural Sciences. It was introduced to Fujian for experimental cultivation and test-crossing with restorer lines. Many of the hybrids resulted from the crossing tests showed excellent agronomic traits, a stable male sterility, easy seed production, improved and early flowering, as well as relatively concentrated, strong combining and restoring abilities. The transmission of early maturity inheritance was strong between generations of the hybrids with traits derived from Taifeng A resulted in the prematurity or late-maturity varieties, including those were less photosensitive. An outstanding feature of these hybrids was their high grain quality for processing and desirable exterior characteristics for commercial purpose. Consequently, many new varieties of the combinations, such as Taifengyou 2098, Taifengyou 656, Taiyou 202, Taifengyou 2197, Taiyou 676, and Taiyou 2328, had been accepted and released for promotion by Fujian Province Crop Variety Examination and Approving Committee. Moreover, Taifeng A offered a substantial potential for further applications. It was highly recommended for breeding new varieties by crossing it with different restorer lines.
