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.Item Reaction of different types of ginger to bacterial wilt caused by Pseudomonas solanacearum (Smith) Smith(Kerala Agricultural University, 1982) Indrasenan, G; Vasantha Kumar, K; James Mathew; Mammen, M KItem Resistance of some rice varieties to 'udbatta' disease in Wynad(Kerala Agricultural University, 1982) Indrasenan, G; Sreekumar, V; Jim Thomas; Mammen, M K
