Effect of grafting on growth and incidence of phytophthora blight and bacterial wilt of pepper (Capsicum annuum L.)

“…Some rootstocks of wild species such as wild Solanum are known to emerge slowly and have poor germination (Gisbert et al, 2011). In this study, commercial varieties exhibited high percent germination, but some breeding lines showed lower percent germination.…”

“…This can be achieved by using rootstocks that have resistance to soilborne diseases or pests, tolerance to abiotic stress, selective absorption of available nutrients, high vigor and good compatibility with the scion (Davis et al, 2008b;Gisbert et al, 2011;Lee and Oda, 2003;Rivero et al, 2003). In this study, C. annuum commercial rootstocks and breeding lines for rootstock were tested for resistance to Phytophthora blight and bacterial wilt as well as their graft compatibility to commercial pepper cultivars, and have confirmed that the new pepper rootstock is resistant to both Phytophthora blight and bacterial wilt.…”

“…In this study, commercial varieties exhibited high percent germination, but some breeding lines showed lower percent germination. Grafting success does not only depend on environmental factors and skill of the grafter but also on graft compatibility between rootstock and scion (Davis et al, 2008b;Gisbert et al, 2011). Even though the scion and rootstock are same species (C. annuum L.) in grafted pepper production, grafting success is affected by the combination of scion and rootstock.…”

“…It has been also reported that pH, flavor, sugar, color, carotenoid content, and texture can be affected by grafting and the type of rootstock used and the rootstock/scion combination must be carefully chosen for optimal fruit quality (Davis et al, 2008a;Gisbert et al, 2011). In this study, we found no differences for yield and apparent fruit quality among non-grafted peppers or peppers onto 'Tantan' and selected breeding lines ('PR 920', 'PR 921', and 'PR 922').…”

“…However, there were some differences for apparent fruit quality among commercial and breeding rootstocks. For example, rootstocks affected fruit length, possibly due to changes in the concentration of growth regulators induced by the rootstock (Gisbert et al, 2011).…”
