The Hardy Citrus of Texas — Part I
Brown’s early breeding work and the challenge of combining cold tolerance with eating quality.
Original report: C. T. Kennedy, reporting from the notes of John R. Brown, M.D.
An original World of Citrus summary. Historical observations retain their original context; reported survival is not a guaranteed planting limit.
The breeding problem
Kennedy’s account follows Brown’s search for citrus that could produce enjoyable fruit beyond established growing regions. Many seedlings reproduced their mother plant rather than expressing the intended cross, making seed-parent choice central to the work.
Working with trifoliate ancestry
Brown explored Temple, citrange, citrummelo, and mandarin families. Trifoliate ancestry offered cold tolerance, but undesirable flavors often persisted. Fruit appearance, vigor, and survival did not reliably predict eating quality.
Lessons from the trials
Repeated freezes exposed differences among siblings and between grafted and own-root trees. Citemple, Sanford-derived hybrids, and Taitri illustrate the uneven progress toward useful fruit. The account also records failed crosses, uncertain identities, and lost plants.
A correction worth retaining
A correction states that fingered fruit forms arose spontaneously; the earlier suggestion of Buddha’s Hand pollen was mistaken.
