Evaluation of selected gonda (Cordia myxa L.) genotypes on different rootstocks

Abstract

A study was conducted to evaluate high yielding gonda selections on three rootstocks, viz. large fruited gonda, small fruited gonda and goondi. The genotype CAZRI-G-2025 showed vigorous growth compared to others on all the three rootstocks. Goondi rootstock showed dwarfing effect with more lateral spread resulting in increased canopy area. The higher scion/stock ratio on goondi rootstock resulted in inverted bottleneck symptom at bud union compared to scion:stock ratio close to one on other two rootstocks. The mean fruit yield of gonda was higher on small fruited gonda compared to its own seedling rootstock irrespective of genotypes. The mean fruit yield over the years was highest in genotype G-2025 followed by G-2012 and G-2011 irrespective of rootstocks. Significantly higher fruit yield was recorded in genotype G-2025 as compared to other two genotypes. Contrary to other characters fruit yield showed decline in all the three genotypes when budded on goondi during 2010 to 2012, while it exhibited progressive increase on the other two rootstocks.
