Performance of coorg mandarin (Citrus reticulata blanco) on different root stocks under the agroclimatic conditions of Wynad

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.
