Notes

Vanuatu - CIRAD/MAFF Datafile: VAN___DS VAN - CIRAD/MAFF Hybrid trial Germplasm: 19 hybrids descended from UA x UA and Amelonado x UA were compared. Environment: Methods: Hybrid trial was planted in 1986 at Valeteruru station using a randomised single tree design spaced at 3 x 2.5m. Results do not take into account the effects of a cyclone in 1992. Glyricidia shade was eliminated from 1988. Productivity was assessed using a value of 0.38 to convert fresh bean weight to dry bean weight. The ratio of production to vigour was calculated by dividing the total number of pods by trunk diameter at four years after planting. Results cover the period January 1988 to December 1991. In addition to the good showing of certain hybrids for their early maturity, their high yield and their technological qualities (large bean size), study of the first five harvests show their better performance vis-a-vis Phytophthora spp. The distribution of production curves from one hybrid to another are analysed in relation to the local rainfall regime and the study of a type of resistance by evasion of these cocoa hybrids is discussed. Some cocoa plants, characterised by a production synchronised and timed to accommodate the rainy season (February/March) gives interesting results and suffers fewer losses thanks to the timing of peak production (May/June).

Malaysia - Quion Hill, Sabah and Ulu Dunsun, Sandakan Datafile: DIS_VSDS - Disease reaction to VSD Descriptors: Resistance to infections from Vascular Streak Dieback Environment: Set 1 assessed at Quoin Hill at seedling stage in a nusery with the source of natural inoculum from surrounding infected mature fields. Sets 2 and 3 were evaluated at the mature tree stage. Germplasm: 79 hybrids evaluated in three sets. Set 1 consists of Sabah mixed hybrids raised specifically for this purpose at Quoin Hill, Sabah. Sets 2 and 3 are progeny trials established at Quoin Hill, Sabah and Ulu Dunsun, Sandakan respectively. Experimental conditions: VSD disease severity was recorded at intervals of one to two months throughout the epidemic period or at longer intervals throughout the rest of the year. Apparent infection rate (r or ADPC (area under disease progress curve)) are used as criteria to compare differences in the resistance of the hybrids. r is obtained by regressing In(1/1 - x) against time in months where x is the disease severity index. Differences between any two r values is tested using a t - test. ADPC is calculated and analysed using analysis of variance.
