Abstract

The present study was conducted to measure the seed health using standard blotter paper and agar plate test from four different commercial wheat cultivars in rain-fed areas of Punjab, Pakistan. The results showed that wheat cultivars were infected with Fusarium sp.  (35.5%), followed by Aspergillus Spp. Aspergillus niger (20.8 %) & Aspergillus flavus (26.1%) and Alternaria sp. (17.6%). Among the wheat cultivars from rainfed areas, “Hashim-08” was highly infected with the percentage of 33.6. Similarly, 28.4% infection rate was found in “Atta Habib” followed by “Pak-2013” (16.7%), Shahkar-2013 (16.6%), Chakwal-50 (5.7 %). Being a staple food of Pakistan wheat crop needs to be quarantined timely to protect the plant with seed borne pathogens which can cause huge crop loses and may become a source of inoculum of diseases. 'These findings highlight the urgent need for effective seed health management practices to mitigate yield losses and ensure wheat production sustainability in Pakistan.
