| description | Sorghum is an important cereal crop, cultivated both in kharif and rabi seasons. Especially rabi sorghum is known for
their grain quality and used exclusively for human consumption. The present study was undertaken to induce variability
through physical and chemical mutagens for morphological and yield-contributing traits. A popular rabi sorghum
variety, Parbhani Moti was initially irradiated with gamma rays (100-400 Gy), ethyl methane sulphonate (0.1- 0.4%
EMS) and their combinations. Based on the univariate analysis, mutants with early flowering (63 days), mid tall (90
cm) and long panicles (21 cm) were identified across various mutagenic treatments in M2 generation. Gamma ray and
EMS combined treatment showed the highest grain yield (85 g/plant) with high SPAD values compared to parent. High
heritability value of 74.6 per cent was observed for grain yield with genetic advance and ranged from 1.22 to 19.96
per cent across different treatments. Significant positive correlation between SPAD values and grain yield and panicle
length were observed. Cluster analysis based on Euclidean distance grouped all the mutants into four clusters with
those derived from gamma rays (400 Gy) emerging as highly diverse. Promising mutants identified in this study would
serve as genetic resources for recombination breeding. |
