Kester, A Productive Late Bloom Almond Variety from University of California Davis By TOM GRADZIEL | Department of Plant Sciences University of California, Davis, CQA THE VARIETY KESTER WAS developed as a pollenizer for Nonpareil that combines good kernel quality and productivity with a later flowering time for reducing vulnerability to flower diseases and frost damage. Kester’s high productivity and later flowering time also make it a promising alternative to the variety Padre in Padre/Butte plantings. Kernels are similar to Nonpareil in shape and size, though the seedcoat tends to be darker and slightly rougher. The seed parent of Kester was Tardy-Nonpareil, a bud-sport mutation of Nonpareil that retains Nonpareil’s good kernel qualities and disease resistance but flowers 10 days after Nonpareil. The Kester tree is vigorous and upright to spreading, being similar to slightly smaller than Nonpareil in final tree size. Production occurs on a combination of spurs and terminal shoots. This growth habit supports high productivity with an open tree architecture that allows greater light penetration and air circulation to the canopy interior, thus reducing vulnerability to blossom, foliar and nut diseases. Kester Evaluation Kester was developed at the University of California Almond Breeding Program at Davis, California with long-term support from the Almond Board of California. The program was developed to breed new varieties and germplasm to meet the emerging needs of the expanding California industry. This includes the long-term, regional testing required to identify potentially serious problems in new variety releases before largescale grower plantings. Towards this 16 West Coast Nut September 2019
goal, Kester has been evaluated for over 20 years in large scale Regional Variety Trials as well as a number of smaller grower trials in the northern and southern Sacramento Valley as well as the northern, central and southern San Joaquin Valley. During this 20-year regional evaluation, Kester showed no major vulnerability to important diseases and remain completely free of the genetic disorder Noninfectious Bud- Failure. Navel orangeworm damage was also consistently low. Nuts are well-sealed at maturity while providing a high kernel-to-nut crackout ratio. Kernels produced quality in-shell, raw and processed, (including blanched and roasted), product. The occurrence of undesirable kernel types, including double-kernels and kernels having multiple DURING THIS 20-YEAR REGIONAL EVALUATION, KESTER SHOWED NO MAJOR VULNERABILI- TY TO IMPORTANT DISEASES AND REMAIN COMPLETELY FREE OF THE GENETIC DISORDER NONINFECTIOUS BUD-FAILURE. ” “ embryos was also low, being similar to Nonpareil. Utilizing Tardy-Nonpareil to Delay Bloom Utilizing the Tardy-Nonpareil budsport as a parent was successful in delaying bloom time by approximately one week while maintaining good kernel quality and productivity.
