Narrative
Inbred Hi82 has a long pedigree of 72 generations of breeding and was formerly known as Hi38c1. Hi82 traces to a sugary-1 inbred called AA8 derived in 1967 from ‘Hawaiian Sugar’ as S6 line A19-6-1-1-1-1. It was fully resistant to the MMV that had crippled sweet corn production in Hawaii. AA8 became the parent of first two commercial tropical sweet corn hybrids ‘Hi38’ and ‘Hi68’, single crosses at one time marketed by Northrup-King and based on temperate parents P39 and Il442 (Brewbaker, 1968). These early hybrids were designated ‘hapa-Hawaiian’ (i.e., half-Hawaiian) and their failure to provide commercially acceptable disease resistance led to their replacement with hybrids based on 100% tropical parentage. AA8 was then converted to bt1 and renamed AA8bt. It was notable for resistance to fusarium that kills temperate sh2 inbreds in Hawaii's wet winter soils. Later AA8bt was converted to Ht1 and Rp1-d genes for turcicum blight and common rust resistance, but these soon failed as a result of racial evolution. After 14 generations of selection for tenderness, yield, and horticultural traits, AA8bt was renamed Hi38 in 1979. It was chosen as the male parent for the first commercial release of ‘Hawaiian Supersweet #10’ and became the primary test cross parent for all new inbreds, entering the pedigree of synthetics such as Hi bt Syn 2 (Brewbaker, 1998). Eight generations involving hundreds of sublines were added to improve general resistance to common rust (Rp1-d having failed) and to improve testcross performance, ear tip cover, and earworm resistance and it was renamed Hi38a in 1987. A second cycle of eight generations of improvement led to Hi38b and involved the incorporation of C cytoplasm (later discarded), erect leaves, and high stay-green. A final cycle of 10 generations was focused on green inner silk and high combining ability for tenderness. A set of 23 superior sublines was evaluated as lines per se and in test cross yield trials during the years 1993 to 1997, resulting in selection and release of Hi38c. Related sublines that have been retained in HFS include Hi38-47 with high tenderness and Hi38-71 that is homozygous for a recessive aphid resistance gene (So et al., 2009). Hi38 was also converted to white kernels through crosses in 1990 to a Nigerian white flint inbred TZi17 followed by six backcrosses over 28 generations. White-seeded subline Hi38cy10 is marked by upright leaves and greatly increased resistance to southern rust compared with its Hi82 parent (Table 3), and commercial white hybrid ‘Sweet Cynthia’ is the single cross Hi36cy1 × Hi38cy10.
