Chickpea (Cicer arietinum.) is grown extensively in India as an important legume crops. A quality seed is required to increase the production of chickpea qualitatively and quantitatively. Hence it is imperative that seeds must be tested for seed-borne mycoflora (seed-health), before they are sown in the field. In the context, a study was conducted to work out the diversity of seed-borne mycoflora in relation to different chickpea varieties. Seeds of ten varieties of chickpea were subjected to Standard Purity Work Board technique and Standard Blotter Paper Method technique (ISTA 2007) for the detection and isolation of seed-borne mycoflora. After incubation of seeds, fungi developed on each seed were examined. Standard Purity Work Board technique results revealed that among the different varieties tested, variety KGD 11 was rated as resistant to seed-born mycoflora with 370 healthy seeds, 11 deformed seeds, 10 wrinkled seeds, 30 discoloured seeds and 13 fruiting body seeds followed by Awarodhi with 364 healthy seeds, 25 deformed seeds, 18 wrinkled seeds, 36 discoloured seeds and 21 fruiting body seeds. Variety JG 315 and PUSA 362 was rated as susceptible in respect to physical seed abnormalities with 169 healthy seeds, 58 deformed seeds, 107 wrinkled seeds, 231 discoloured seeds, 72 fruiting body seeds and 203 healthy seeds, 63 deformed seeds, 85 wrinkled seeds, 197 discoloured seeds, 68 fruiting body seeds, respectively. It was evident with the experimentation that chickpea wilt disease causing pathogen Fusarium oxysporum which is the most yield limiting factors in chickpea was found associated with the seeds of all the widely adopted chickpea varieties viz., L 550, BG 3004, Pragati, BGD 72, JG 11, RSG 807, PUSA 362 and JG 315 except two varieties namely KGD 11 and Awarodhi. Variety KGD 11 was found more tolerant for the per cent infection of seed that is 10.00 % under pre-treated (PT) condition and 21.50 % under untreated (UT) condition with 99 % germination (UT), 100 % germination (PT) and five seed associated fungi viz.,Alternaria alternata, Curvularia lunata, Fusarium semitectum, Aspergillus niger and Rhizopus arrhizus.
