Abstract:
Twenty stionic combinations involving scions of five mandarin orange
varieties and four rootstocks were evaluated for their performance under the agroclimatic
conditions of Wynad, Kerala since 1980. The first six years study showed
that Coorg mandarin on Rough lemon was the most vigorous combination in respect
of all the biometric characters recorded. Rough lemon was the most invigorating
rootstock, while Trifoliate stock induced dwarfness of scions. Though it was too
prematureto assess the yield potential, data recorded in 1984, 1985 and 1986 showed
that Coorg mandarin on Rough lemon was comparatively higher in yield than most
other combinations. With regard to quality also, it was on par with other combinations.
Further studies will be continued.
