DESCRIPTION OF THE NEW VARIETY

(22) The following description is in accordance with UPOV terminology and the color terminology herein is in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.), 3rd edition published in 1995.

(23) The color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions.

(24) Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech is aptly descriptive. Color names beginning with capital letter designate values based upon The R.H.S. Colour Chart published by The Royal Horticultural society, London, England, 1995.

(25) The following detailed description of the new variety is based upon observations taken of plants and fruits grown underglass, i.e., under tunnel, in Cartaya (Huelva), Spain, 7 W., 37 N., 45 feet elevation.

PROPAGATION

(26) The new variety is principally propagated by way of root cuttings. Although propagation by root cuttings is presently preferred, other known methods of propagating blackberry plants may be used. Blackberries root and develop well after transplanting.

(27) Plablack 1401 is propagated by root cuttings. It is a primocane variety with fruit production from the middle of September through the end of December on primocanes and in the ensuing year from the end of April through the beginning of June. Plablack 1401 is a self-fertile variety. It produces large quantities of pollen throughout the seasons and pollination is good.

(28) Plants described are from high elevation nursery in Segovia, Spain, 3 59W., 41 22N., 2742 feet elevation. Trials were pursued in in Cartaya (Huelva), Spain. Date of planting (two years) of the plants was June 14 in the first year and June 15 in the second year. Sample size was three repetitions (every year) with 100 plants per repetition (every year). The growing period in Huelva, Spain, where the observations on primocane production were made, is between about June 15 and June 2 of the following year. Plablack 1401 is a primocane variety, with consistent fruit production from middle September through ending December on primocanes and in the ensuing year from ending April through the beginning of June. After planting as aforesaid, plants are grown in raised beds under tunnel. Water and fertilizer were applied through drip irrigation.
