Abstract:
Performance of six promising rootstocks of mandarin under the climatic
conditions of Wynad was evaluated for the first five years after planting. The data
presented in this paper indicated that Carrizo Citrange, Rough lemon and Troyer
Citrange had given better performance than others in respect of most of the
parameters understudy. Rangpur lime and Cleopatra mandarin were also performed
satisfactorily whereas Trifoliate orange had given poor performance. However,
consistent good performance was not seen in any of the rootstocks understudy
presumably due to the variability of growth pattern as influenced by the rootstocks
during the early years of growth. General observation revealed that Trifoliate orange
exhibited retarded growth during the early stages and was comparatively free from
chlorosis.
