'Creek' (Nut photo) Orig. from a controlled cross thought to be ('Mohawk' X 'Starking Hardy Giant') made in Brownwood, TX by L. D. Romberg. Cross made in 1961. Tested as 61-6-67 by T. E. Thompson, W. D. Goff, M. L. Nesbitt, R. E. Worley, R. D. O'Barr and B. W. Wood and released in 1996. Simple sequence repeat profiles of both parents disqualify Starking Hardy Giant as a parent due to inconsistencies at the cin13 and ga38 loci (Grauke, L. J., Mendoza-Herrera, M. A., Loopstra, C. A., and Thompson, T. E. Microsatellite markers for verifying parentage of pecans. HortScience 41(3): 515. 2006) and at the wga118 and wga4 loci [Mendoza-Herrera, A., Grauke, L. J., and Binzel, M. Confirmation of SSR markers within a structured collection of pecan [Carya illinoinensis (Wangenh.) K. Koch], cultivars. Plant and Animal Genome XVI Conference. San Diego, CA. Jan. 12-16, 2008 (Abstract P140)]. 'Creek' SSR profiles are consistent with 'Western' parentage at all 14 loci evaluated. Nut: elliptical, with an acute apex and base; round in cross section; 54 nuts/lb, 49% kernel; kernels cream to golden in color, with wide dorsal grooves. Released for its precocity, productivity, and disease resistance for use as a temporary cultivar in the early establishment phase of orchards in the southeast. Mature trees tend to overbear. Protandrous, with mid-season pollen shed and mid-to late-season pistillate receptivity. Moderately scab resistant. Highly susceptible to pecan phylloxera (Phylloxera devastatrix Pergande).
