Evaluation of Long Day Garlic (Allium sativum L.) Ecotypes For Growth, Yield and Quality Performance

Abstract

Twenty four diverse genotypes of long day garlic were evaluated which exhibited significant differences for growth, yield and quality parameters viz., plant height, number of leaf, leaf length, polar and equatorial diameter of bulbs, average bulb weight, number of clove/bulb, total soluble solids and total bulb yield per plot. Among the lines, highest yielding genotype i.e. G-408 AP recorded maximum bulb yield (3.55 Kg/plot and 157.93 q/ha). The genotypes G-408 AP, CITH-G-10 and VLG-2 recorded bulb weight of 44.40 g, 42.60 g and 36.40 g, respectively. Maximum TSS of 42.50 0brix was recorded in genotype UHF-G-12-2 followed by Selection 10-3 (41.500 brix) and G-417 (40.70 0brix). Presence of wide range of variation of mean and coefficient of variations depicted the chance of improvement in the present genotypes through clonal selection and later on could be stabilized and utilized as new varieties for the region. The line G-408 A.P. has potential of highest bulb yield under long day condition of Kumaon hills of Uttarakhand. The genotypes under study showed sufficient genotypic variability, heritability and genetic advance for most of the traits especially economic trait i.e. bulb yield. Apart from it, the significant and positive correlation coefficients were also exists between the traits under study. Hence, there is chance of improvement in the genotypes through clonal selection and better variability in various traits could be developed through clonal selection for further improvement of the crop/genotype.
