Abstract/ Executive Summary:

Twenty two garlic genotypes of local and exotic origin were evaluated during the period from 27 November 2000 to 31 March 2001 at the Spices Research Centre, Bogra, of the Bangladesh Agricultural Research Institute. The results indicated that the germplasm differed significantly as to the different morphological attributes, yield and other desirable traits. The height of plants varied from 42. 50-67. 33 cm whereas, there was no difference as to the number of leaves/plant. Length and width of individual bulb differed from 2.40-3.20 and 2.10-2.71 cm, respectively. The number of cloves/bulb and individual bulb weight were also varied significantly. The entries showed variable degree of pungency. Per hectare yield (t) of garlic genotypes varied from 2.18-6.29, being lowest in GC003 and highest in GC007. Considering pungency as a positive trait of selection and yield potentiality also with other parameters, the lines GC002, GC006, GC007, GC010, GC011, GC016, GC017 and GC021 were found promising.

Start Date: 27-11-2000

End Date: 31-03-2001

Program Area: Variety and Species

Commodity: Garlic

Objectives:

To evaluate the performance of the 22 garlic germplasms in respect of their yield and other desirable traits.

Methodology:

The investigation was carried out at the Spices Research Centre, Bogra, of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the period from 27 November 2000 to 31 March 2001. The experiment was laid out in a RCBD with three replications. Twenty-two garlic genotypes were collected from home and abroad, comprised 22 different treatments of the study. Unit plot size was 2.00x0.60 m. Cloves of uniform size were selected in case of each of the germplasm for planting. Planting was done on 27 the November, 2000 following 20x10 cm spacing; thus accommodation 60 plants per unit plot in three rows, each accommodating 20 plants. The crop was fertilized with cowdung, Urea, TSP and MP @ 5000, 260, 130 and 160 kg ha^-1, respectively. The entire quantity of cowdung and TSP were applied at the time of final land preparation. Urea and MP were applied in two equal splits, 20 and 50 days after planting. Irrigation along with other intercultural operations were done as and when required. The crop was free from the attack of any major insect pests and diseases during the growing period.Twenty plants were selected at random from each unit plot for collection of data on different morpho-agronomic and yield attributes. The organoleptic quality of the genotypes pertaining to pungency was estimated by a panel of judges comprised 12 persons of different age group. The recorded data were analyzed statistically and the treatment means were separated by DMRT for interpretation of results.

Achievement/Findings:

Considering yield potentiality, pungency and other desirable attributes, the genotypes GC002, GC006, GC007, GC010, GC011, GC016, GC017 and GC021 were considered promising and could be selected preliminarily for further trial with a view to develop variety(ies).
