“…These results are consistent with those found by Gonçalves et al (2005) and Martins et al (2000) in a study conducted for the trait rubber yield at the same experimental locations, confirming the possibility of using the genotypes established with individual selection within progenies.…”

“…The opposite occurs for full-cleft method, in which, for subsequent grafting, it is required to partitioning a graft branch from mother plant. Vegetative growth changes among the different rootstock treatments may have arisen from intrinsic characteristics of each tested rootstock, being even possible that, in addition to the rootstock's favoring or not of vegetative growth, it also has an effect on crop cycle duration (MARTINS et al, 2000;PICOLOTTO et al, 2009). However, less promising results for all plant growth characteristics, after grafting, in particular for LN and FA, were observed when scions were grafted on S. pennellii through both methods and on cocona and physalis through approach method.…”

-This paper aimed to assess tomato grafting on different solanaceous species through two grafting methods. Scions were cut from cultivar Santa Cruz Kada seedlings. A fully randomized experimental design was carried out with treatments in a 9 x 2 factorial scheme. As rootstocks, four accessions of mini-tomatoes (0224-53, RVTC 57, RVTC 20 and 6889-50 -Solanum lycopersicum L); two species of wild tomato (Solanum habrochaites var hirsutum 'PI-127826' and Solanum pennellii 'LA716'); other two tomato species [Solanum, cocona (Solanum sessiliflorum) and physalis (Physalis peruviana)] and a control with cultivar Santa Cruz Kada (auto-graft) rootstocks were used. In addition, two grafting methods were evaluated full cleft and approach graft. Fifteen days after grafting, plants were assessed for graft-take percentage; root length; plant height; leaf number; foliar area; root, stem and leaf dry matter; and ratio between shoot and root dry matter. Based on the results, we may state rootstock and grafting interaction had effect on both graft-take rate and plant development. Overall, the studied plants should be recommended as rootstock, except for 6889-50 mini-tomato (S. lycopersicum L.) and S. pennellii. Full cleft grafting was most suitable for cocona and physalis, while the approach method showed better results for the mini-tomato accessions 0224-53, RVTC 57 and RVTC 20, as well as for S. habrochaites.Keywords: Solanum lycopersicum.

PEGAMENTO DE ENXERTOS DE TOMATEIRO EM DIFERENTES SOLANÁCEASRESUMO -O presente trabalho teve como objetivo avaliar o pegamento de enxertia de tomateiro, em diferentes espécies de solanáceas e por diferentes métodos de enxertia. Foram produzidas para enxerto mudas de tomateiro da cultivar Santa Cruz Kada ® . O delineamento experimental utilizado foi o inteiramente casualizado, com os tratamentos arranjados em esquema fatorial 9 x 2, avaliando-se como porta-enxerto: os acessos de minitomate 0224-53, RVTC 57, RVTC 20 e 6889-50 (Solanum lycopersicum L); as espécies silvestres de tomateiro Solanum habrochaites var hirsutum 'PI-127826' e Solanum pennellii 'LA716'; duas outras espécies Solanum, cubiu (Solanum sessiliflorum) e fisales (Physalis peruviana); e o tomateiro cultivar Santa Cruz Kada ® como testemunha (auto-enxertia), e avaliados dois métodos de enxertia: fenda cheia; e encostia. Aos quinze dias após a enxertia, as plantas foram avaliadas quanto ao: índice de pegamento de enxertia; comprimento de raiz; altura das plantas; número de folhas; área foliar; massa seca das raízes, do caule e das folhas; e relação massa seca da parte aérea/massa seca das raízes. Com base nos resultados obtidos, foi possível verificar que o índice de pegamento e o desenvolvimento vegetativo das plantas após a enxertia em tomateiro foi influenciado significativamente pela interação (porta-enxerto x método de enxertia). Dentre os porta-enxertos avaliados, todos podem ser recomendados, exceto o acesso de minitomate 6889-50 (S. lycopersicum L.) e a espécie...

“…Later, Ng et al (1981) showed that rootstock influenced significantly the growth and yield of the scion, but there was no rootstock interaction. Selection of good rootstocks is therefore Crop Breeding and Applied Biotechnology, v. 2, n. 3, p. 445-452, 2002 (Gonçalves, et al, 1994;Martins et al, 2000. ) This study is expected to throw some light on the combining ability for rubber yield and growth vigour and on the process of choosing better rootstocks among the existent clonal rootstock material for future exploitation.…”

Rootstocks and scions combinations of five rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) MuellArg.] clones were evaluated for rubber yield and growth vigor to detect the rootstock with the best general combining ability (GCA) and the best specific combining ability (SCA), using the method 1, suggested by Griffing. The clones (scions) involved were: IAN 873, RRIM 600, RRIM 701, PB 235 and GT 1 grafted in five different rootstocks from illegitimate seeds of the same clones. The ANOVA mean squares for GCA and SCA reciprocal effects were highly significant for both characters. The general GCA: SCA ratios were 24:1 and 4:1 for rubber yield and growth vigour, respectively. The rootstock of the RRIM 600 clone was the best general combiner for rubber yield (g i = 8.25), followed by the PB 235 (g i = 5.20).Although negative, the rootstock of the RRIM 600 clone showed the best GCA (g i = -0.0354) for growth vigour, followed by rootstock of the GT 1 clone which presented a g i = -0.5194 value. The maximum SCA effects for rubber yield (s ij = 5.55) was obtained by IAN 873 rootstocks combined with the RRIM 600 clone as scion, followed by the PB 235 (rootstock) combined with the RRIM 600 scions (s ij = 3.06). For growth vigour, the best specific combining ability effect of s ij = -1.64 was obtained by the IAN 873 clone in combination with the RRIM 701 clone, with their respective rootstock and scion. As for rubber yield, the RRIM 600 rootstocks were classified as the best general combination. In addition, the IAN 873 rootstocks combined with the RRIM 600 scion showed the best specific combining ability. KEY WORDS:Hevea brasiliensis, rubber tree, rootstock, scion, general combining ability, specific combining ability.has not been well emphasized and its benefits not clearly illustrated.
