Abstract/ Executive Summary:

Variability and correlation studies were carried out on yield and eight component characters of 190 germplasm accessions of lentil (Lens culinaris Medik.) collected In Bangladesh. The characters showing the highest coefficients of variation were seed yield per plant, number of pods/plant, number of primary and secondary branches/plant, while the lowest values for coefficient of variation were shown by time to maturity and number of seeds/pod. Correlation studies showed that seed yield per plant had a highly significant positive correlation with number of pods/ plant, number of seeds/pod, number of primary and secondary branches/plant and time te 50% flowering. These characters were also significantly correlated among themselves except for the association between the number of seeds/pod and time to 50% flowering. The result indicated that profusely branched plants with a high number of pods tend to have a higher yield potential.

Program Area: Variety and Species

Commodity: Lentil

Objectives:

To Find out Variability and correlation on yield and eight component characters of 190 germplasm accessions of lentil (Lens culinaris Medik.) collected In Bangladesh.

Methodology:

One hundred ninety germ plasm accessions collected from different locations in Bangladesh were evaluated in a germplasm evaluation trial. The trial was carried out at the Regional Agricultural Research Station, Ishurdi. Pabna. The genotypes were sown in non-replicated single row plot of 4 m long with lentil-5 as check, after every 10 test entries on the first week of November 1986. Spacing was 30 cm between rows and 2 cm between plants within a row. Only 0.2% of ZnSO₄ was applied in the 2nd week of December. For uniform germination, only one post-sowing irrigation followed by one mulching was applied. Ten plants/plot were randomly selected for observations on seed yield and other component characters such as time to 50% flowering, time to maturity, plant height, number of primary and secondary branches/ plant, number of pods/plant, number of seeds/pod, and 1000-seed weight.

Achievement/Findings:

Correlation studies showed that seed yield per plant had a highly significant positive correlation with number of pods/ plant, number of seeds/pod, number of primary and secondary branches/plant and time te 50% flowering. These characters were also significantly correlated among themselves except for the association between the number of seeds/pod and time to 50% flowering. The result indicated that profusely branched plants with a high number of pods tend to have a higher yield potential.
