Location assessment of wilt causing pathogen Fusariumo xysporum f. sp. ciceri in seeds of chick peavarieties

Gram is a type of plant of pulse crops which is having the seed in a pod, that's containing two or three peasin a single pod. Grambelong to the order Fabales and family Fabaceae is an herbaceous annual, havingbranching close to the ground with semi-erect to semi-spreading habit. This crop (chickpea) is subjected toattack by a number of fungal, viral, bacterial and nematode diseases. Inadequate information is available onthe Fusarium wilt of gram as regards to seed-borne nature. In present studies total ten varieties seed, inwhich five susceptible viz. Radhey, JG-62, Pusa-372, Pusa-329 and ICP-1454 and five resistant viz., Avarodhi, KWR-108, KGD-1168, JG-315 and JG-130 (resistant to disease under field condition) weretaken. The test pathogen was detected in the all-susceptible varieties of chickpea seeds ranging from 11–26%.The average recovery percentage from sodium hypochlorite (NaOCl) and mercuric chloride (HgCl₂) pre-treated seeds were 13.6 and 5.6 percent. These were some differences in the recovery of seed infection inthe varieties. It was found minimum in Pusa-329 (11%) and maximum in JG-62(26%) followed by ICP-1454 (24%), Radhey (16%) and Pusa-372 (14%) respectively. Test pathogen was not presented in resistantvarieties seeds except only in Avarodhi (5%) variety. Other remaining resistant varieties like KWR-108, KGD-1168, JG-315 and JG-130 did not carry seed infection of the test pathogen.
