Gamma irradiation effect on morphological character of M1 generation of okra

Abstract

The study was done to assess the impact of various dosages of gamma beams (150, 300, 450 and 600Gy and zero portions as control) on different morphological parts of two assortments of Abelmoschus esculentus named BARIdherosh-1 and BARIdherosh-2. The experiment was spread out in a randomized complete block design (RCBD) with three replications. The consequences of various portions showed that gamma illumination essentially influences all boundaries i.e., plant height, number of leaves per plant, number of pods per plant, length of pod and number of seeds per plant. Plant height was significantly increased at 600 Gy (133.6cm) and 150 Gy (155.2cm) for BARIdherosh-1 and BARIdherosh-2 respectively as compared to control. At 300Gy (16.35) and 450Gy (16.23), maximum pods per plant were found for BARIdherosh-1 and BARIdherosh-2. For BARIdherosh-1 maximum number of seeds per plant (590.17) was observed at 150 Gy and for BARIdherosh-2 (542.33) it was 450 Gy.
