Abstract

Aloe vera (Aloe barbadensis) is a perennial, succulent plant belongs to the family Liliaceae. Aloe vera leaf rot is one of the major limiting factors in Aloe vera production, which decreases leaf, gel quantity and quality significantly. The experiment was conducted to evaluate the genotypes of Aloe vera against leaf rot disease Out of 26 genotypes, none of genotypes was found the free from disease, three genotypes viz, IC-111280, IC-112531 and IC-112513 were highly resistant, four genotypes viz., IC-111279,IC-112518, IC-285626 and IC-283655 were resistant, nine genotypes viz, IC-310618, IC-471886, IC-310904, IC-112569, IC-112519, IC-112532, IC-310611, IC-310617 and IC-310596 were moderately resistant and rest of the genotype were moderately susceptible to highly susceptible against the disease.

Highlights

Aloe vera (Aloe barbadensis Miller) is a perennial, drought resisting succulent plant belong to the family Liliaceae which its believed to have originated in African continent in Egypt (Daodu 2000)
There are over 250 species of A. vera growing around the world only A. barbadensis, A. ferox and A. arborescence are used as herbal drugs
The leaf rot disease severity noted on each genotypes was rated following a severity scale from 0 to 5 (Banerjee and Kalloo 1987) [where 0 = no disease; 1 = 1% disease (HR: highly resistant); 2 = 1–10% disease(R: resistant); 3 = 11–25% disease (MR: moderately resistant); 4 = 26–50% disease (S: susceptible) and 5 = more than 50% disease (HS: susceptible)]

Summary

Introduction

Aloe vera (Aloe barbadensis Miller) is a perennial, drought resisting succulent plant belong to the family Liliaceae which its believed to have originated in African continent in Egypt (Daodu 2000). A. barbadensis which revealed three types of leaf spots and root rot disease (Sharma and Samota 2007). The leaf yield varied from 0.599 to 2.922 kg per plant per year due to disease in different genotypes (Abhila and Jessyeutty 2010).
