Abstract
This study aims to study aims to evaluate the genetic variability and genetic advance for bulb yield and components of different mutant lines of Garlic (Allium sativum L.) under Chhattisgarh plains. The experiment was laid out in Randomized Block design with three replications 21 mutant lines viz., IG C-1, IG C-2, IG C-3, local check, IG M-2021-1, IG M-2021-2, IG M-2021-3, IG M-2021-4, IG M-2021-5, IG M-2021-6, IG M-2021-7, IG M-2021-8, IG M-2021-9, IG M-2021-10, IG M-2021-11, IG M-2021-12, IG M-2021-13, IG M-2021-14, IG M-2021-15, IG M-2021-16, IG M-2021-17. Data were analyzed to work out performance of mutant lines, to assess genetic variability, heritability, genetic advance. The character taken under study include plant height (cm), number of leaves, collar height (cm), collar thickness (cm), fourth leaf length (cm), fourth leaf width (cm), polar diameter (cm), equatorial diameter (cm), neck thickness (cm), number of cloves, average weight of bulb (g), TSS, days to maturity, weight of ten outer cloves (g), marketable yield (t ha-1), total yield (t ha-1). Estimates of genetic parameters for various character under study revealed that high genotypic co-efficient of variation was found in general compared to phenotypic co-efficient of variation. Heritability estimates under present investigation ranged from moderate to high. High heritability estimates recorded for collar height, weight of outer ten cloves, marketable yield, total yield. High heritability coupled with high genetic advance was recorded for collar height, marketable yield and bulb yield.
