PERFORMANCE OF OKRA GERMPLASM WITH SPECIAL REFERENCE TO YELLOW VEIN MOSAIC VIRUS

Abstract

The experiment Was undertaken to study the performance of okra germplasm with special reference to yellow vein mosaic virus among 36 accessions at the 1-l0rticult1lre Farm Division, lIorticulwre Research Centre, Bangladesh Agricultural Research Institute, .Ioyclebpur, Gazipur, during the period from April 2007 to August 2007. There was a wide range of clilThrent parameters. The maximum (169.37 em) plant height was observed from accession number 14 and the maximiflhl spread of plant was found from accession number 138 (14.62) was recorded from accession number 219 and 114 respectively. At 80 DAS the plant performed the maximum (94.2) number of leaves was obtained from accession number 138. The maximum leaf breath (35.1 cm) was recorded from accession number 148. The minimunl (36.39) and the maximum (68.08) (lay's was required for days to first flowering were from accession number 144 and 114 respectively. The minimum (14.27%) plant was infested by virus at 75 DAS in accession number 139 compare to other accessions number. So, accession number 139 was identified as agronomicallY acceptable resistant line against okra yellow vein mosaic virus.
