    The Grapefruit/Pomelo Products

    Texas has evolved into the leading grapefruit producer in the country. Texas contributions to the grapefruit industry started with a significant start in 1929. A. E. Henninger of McAllen, Texas discovered Redblush grapefruit (aka Ruby, Red Marsh, Red Seedless, Henninger Red) as a limb sport in the Thompson grapefruit orchard. This grapefruit is a historical marker – it is the first citrus variety to receive a patent – U.S. Plant Patent No. 53. As a McAllen resident and citrus scientist, this historical marker in my hometown McAllen, Texas makes my muscle cells contract and elevates my hair follicles. Thanks to Mr. Henninger who started a saga of grapefruit gurus in the Rio Grande Valley.

    Another limb sport from Thompson grapefruit was discovered and introduced in 1934 by J.B. Webb of Donna, Texas in the Rio Grande Valley.

    Ruby or Redblush. Seedless, red flesh, often thin rind and smooth surface, juicy, good flavor, ships and stores well, mid-season maturity.

    Another discovery of pigmented Texas grapefruit was Ray Ruby in Weslaco, Texas by Robert Ray, 1970. This is identical to Henderson, another Texas product discovered by Samuel Henderson in 1973. It started as a limb sport on Ruby Red. Henderson peel is more attractive than Ruby Red and the flesh is redder. Henderson gave birth to Florida’s Flame grapefruit which is a nucellar Henderson.

    Hudson is a red pigmented grapefruit from Foster identified in the 1930 by a Texan, Charles Hudson.

    Dr. Richard A. Hensz, breeder at Texas A&I Citrus Center took seeds from Hudson, and irradiated to induce mutation. Star Ruby is the result of Dr. Hensz’s breeding work, 1970. Star Ruby has deep-red flesh.

    Rio Red GrapefruitsThe Rio Red grapefruit is another grapefruit released from the Texas A&I University in 1984 by Dr. Richard A. Hensz. This is a natural mutation on a tree produced from irradiated budwood which came from Ruby Red seedlings, referenced A&I -I-48S. The rind is red as in Henderson and flesh color deep red as in Star Ruby.

    Texas Red is another product of Texas A&M University-Kingsville Citrus Center, however it is not officially released yet.  

    A less prevalent, but an excellent early-season fruit is known by Golden grapefruit or Whittaker gold, named after Mr. Leon Whittaker of Edinburg, Texas. It is seedy, the fruit is flat, extra sweet, and less acidic. It matures in October.
