Narrative
Inbred Hi79 has a pedigree of 21 generations of breeding. It originated from inbred bA11 bred by Dr. T. Pulam in Thailand from hybrids of Hi bt Comp 3 (‘Hawaiian Supersweet #9’) and Thai Composite 3-4 that was based on tropical flint composite Suwan 1. Inbred bA11 was one parent of Dr. Pulam's widely grown, 16-row, processing hybrid ATS-2, a single cross that laid the foundation for Thailand's burgeoning supersweet corn industry (Brewbaker et al., 2006). Hawaii breeding began in 1998 with a focus on conversion to green silks and tassels together with improved resistance to MMV and fusarium. The Thai inbred was crossed with ‘Hawaiian Supersweet Silver’ (Brewbaker, 2006) followed by four backcrosses and 17 generations of selfing and sibbing. Green inner silks were achieved evidently as a result of exchanging the original (bt A2) linked genotype of bA11 for the (bt a2) from the Hawaiian parent. Inbred Hi79 is characterized by superior combining ability for kernel tenderness, but kernels have an accompanying high sensitivity to fusarium seedling blight. In fusarium-rich soils, the inbred germinates poorly and seedlings are slow to develop healthy root systems. The plants are notable for stay-green, prolificacy, the persistence of rich green color after physiological maturity, and superior tolerance to turcicum blight. The tassels are large with about twice the branch number of other inbreds (Table 2), and it is suspected to carry the gene Brta (branched tassel) identified by Brewbaker and Yu (2009). The 16-row ears are somewhat irregular and on large cobs (25 mm), and the kernels are deep (13 mm). Its hybrids are called ‘HiThai’ in Hawaii and are of exceptional tenderness. They are attractive in the field with heavy 16-row ears at a low position on tall plants. Marketed hybrid ‘HiThai2’ is the modified single-cross (Hi75 × Hi76) × Hi79.
