5 FULL TRIAL REPORT Introduction There is a continuing need to identify summer fruiting (floricane) raspberry cultivars for commercial production which meet the evolving needs of the market, whilst offering profitability to UK growers. The aim of this project is to evaluate new cultivars and advanced selections from UK and overseas breeding programmes. It is hoped to identify cultivars for the fresh market, which are better than those currently being grown or which offer an extension to the existing harvest period. The cultivars chosen for assessment in the trial will include those that may soon be available to UK growers for planting and those which UK growers have little or no experience of growing in the UK. The objectives of the trial are to identify: Cultivars which can reliably produce higher yields than the current industry standards. Fruit of superior quality than existing cultivars, as regards size, uniformity of shape, colour, texture and flavour, with good shelf life throughout the harvest period. Cultivars with strongly attached laterals which don t need support, which present fruit well to pickers, with berries which are easily detached and thereby cheap to harvest. Cultivars suited to soil or other substrate production, with upright cane habit and suitable vigour making them cheap and easy to grow. Cultivars with cold hardiness and resistance to pests and diseases, thus offering reliable cropping and reduced reliance on crop protection products Agriculture and Horticulture Development Board 1

It is located within a well sheltered south facing commercial planting of raspberries. The soil texture is classified as loamy sand which offers free drainage. The plants were planted and established in field soils, through black polythene mulched narrow, high raised beds. At planting no trellis was in position, but this will be installed in the early spring of 2014, so as to support primocane as it grows. The plants were supplied with trickle irrigation and fertigated from planting onwards. The date of planting each entry varied depending upon the availability from each of the plant suppliers. The majority were planted in June, July and August 2013, although the entries from Graminor in Norway were not available for planting until The exact dates of planting each entry are listed in Tables 1 and 2 (above). Figure 1 (below) illustrates some of the plants following planting. Plants were allowed to establish through The canes were assessed for growth, bud condition and presence of pest/disease early in February 2014, after which the floricane in all plots was cut to ground level. The first flush of primocane was thinned by hand in early May Pest, disease, weed control and crop nutrition were attended to as and when required. From Spring 2014, these were dictated by the requirements of the commercial planting of raspberries that surrounds the trial Agriculture and Horticulture Development Board 3

8 Figure 1. Images of the trial set up at planting Trial design Main entries Four replicates of each of the main entries were planted. Ten plants of each cultivar were planted in each replicated plot, spaced 45 cm apart with a one metre gap between each plot. The plots will be protected during their cropping years by Spanish tunnels. The crop rows will be spaced so that two rows will be covered by each tunnel bay. Each row contains a replicate of each main entry and industry standard cultivars, meaning that the four rows of the main entries will be protected by two tunnel bays. The whole trial plan is set out in Appendix Agriculture and Horticulture Development Board 4

9 Guard entries Guard entries were planted in single plots of 10 plants, spaced 45 cm apart, with one metre gap between each plot. The rows have been spaced to allow three to be covered by a Spanish tunnel bay during their fruiting years. The whole trial plan is set out in Appendix 1. Cane assessments Tables 3 and 4 (below) list the results of the cane assessments made in February It shows that no disease was observed on any of the selections. Bud condition gives a suggestion of earliness (i.e. those with green bud in February such as EM6803/16, EM6804/68 and 0447C-5 are likely to be the earlier selections). It also shows how much growth the canes achieved in their first growing season (planting year). BC , AAC Eden (KO6-2), 0447C-5, Ukee, 0568C, Tulameen Pearl Clone 299-5, BC and Jean d Orléans achieved similar levels of growth to the standards Octavia and Tulameen, producing floricane over 1 m in height. The poor cane growth of the EMR entries was primarily due to their late planting. However in the majority of the plots planted in 2013, the plants had produced extensive root systems by February 2014, including those which had produced few canes or ones of poor stature in the planting year. It was too early to determine cane habit or other growth characteristics of the entries in February Table 3.

11 Plans for 2014 and beyond Primocane produced during the 2014 growing season will be reduced in number by hand on several occasions to leave a stand of six to eight canes per metre of row or an average of three canes per plant to crop in In addition the remaining guard entries will be planted. In 2015 and 2016, yield, berry weight, fruit quality characteristics such as size, colour, firmness and shelf-life will all be recorded. In 2014, 2015 and 2016 the plant characteristics of all the entries will also be evaluated (e.g. plant habit, date of and evenness of bud break, ease of management, lateral pose, strength of attachment, ease of fruit detachment and pest and disease susceptibility). Knowledge and technology transfer No technology transfer has been organised for this project to date. It is planned to produce a PowerPoint presentation in autumn/winter 2014 to display the main and guard entries. The presentation will introduce growers to the advanced selections and new cultivars that have been planted in the trial and include a brief description of plant, pest and disease tolerances, susceptibilities, a picture of the fruit (if available) and the results for any trials they have previously been included Agriculture and Horticulture Development Board 7
