Abstract:

Evaluating the efficiency of using grafted pepper varieties in the Southeast and Central Highlands of Vietnam from 2014-2016, on the ability to grow and develop in production, to meet the needs of pepper growers for tolerance with quick wilt and slow wilt diseases which have been destroying pepper growing areas. Applying the method of interviewing farmers with prepared questionnaires and combining field surveys for evaluation. The research results show that (i) Most grafted pepper were planted scatteredly in Southeast and Central Highlands with rootstock is wild pepper (Piper Colubrinum Link) origin from South America. Most grafted pepper plants had a growth period of 1-3 years until the survey time. There were also plants grown plants with 5-8 years old. Grafted pepper plants were mainly planted in diseased pepper posts in the garden and there was not much pure planting. (ii) Grafted pepper plants have a good survival rate, with 76% of households having gardens reaching a survival rate of over 90% after 12 months of planting and over 83% of grafted pepper gardens growing well. (iii) Grafted pepper plants have good resistance to quick wilt and slow wilt diseases (18-24% of gardens appear with only 1-3% of diease plants); no viral disease has been found; able to withstand waterlogged in growing areas; strong root system. Disadvantages of grafting pepper plants like scattered flowering, less panicles, low fruiting rate, poor drought tolerance so frequent
watering, rootstock’s shoots thrive, so required labors for removing, productivity was lower than normal pepper black pepper, low branching ability,
grafting position were enlarged when pepper was developed. (iv) Yield of pepper plants grafted with scion of Indian black pepper cultivar at the age of 5 years (2014) averaged at 0.6 kg/plant, average yield of grafted scion of Vinh Linh at 3 years old were 0.3 kg/plant. For quality testing of pungency and aroma of grafted pepper was lower than regular pepper through sensory evaluation. Finally, the results of interviews on from August to September, 2019, in the surveyed areas in Southeast and Central Highlands, at present, farmers do not accept to maintain grafted pepper in production because it is not effective.
