Cucumber germplasm
-
The present investigation was under taken with the objectives to estimate genetic variability, heritability and genetic advance for yield and yield contributing components of cucumber. The experimental materials for this investigation were fourteen genotypes of cucumber consisting of parthenocarpic, gynoecious and monecious germplasms crossed in line × tester mating design produced thirty three hybrids (F1). Thirty three F1 crosses along with their parents were evaluated in two environments viz.

Thirteen (Three gynoecious and ten monoecious) germplasm lines of cucumber (Cucumber sativus L.) were characterized by sodium dodecyl sulphate polyacrylamide vertical slab gel electrophoresis (SDS-PAGE). The seed protein could be resolved into total 11 bands distributed in 4 zones i.e. A, B, C and D. Zone A was divided into 5 subzones and 5 bands, zone B has 1 band C has 5 and zone D included 5 bands. Similarity index value ranged from 62% to 100% among all the genotypes. Pgyn-1 showed least similarity 68% with other genotypes.

Field surveys were conducted for collection of CMV virus isolates in bell pepper depicting a wide range of symptoms ranging from mosaic, mottling, yellow discoloration, vein clearing, leaf deformation, shoe stringing or leaf narrowing, stunted growth to reduced fruit size. In an attempt to correlate the symptoms with virus concentration in different isolates, DAS-ELISA was performed on symptomatic plants and CMV was detected in majority of the isolates. It was observed that the plants with shoe stringing (typical symptom of CMV in bell pepper) had the highest O.D.

Cucumbers (Cucumis sativus) are known for their plasticity in sex expression. DNA methylation status determines gene activity but is susceptible to environmental condition changes.
