Abstract:

Barley (Hordeum vulgare L.) belonging to Gramineae family is an important cereal in the countries which have arid and semi-arid type. Among the different diseases occurring on barley, spot blotch or foliar blight caused by Bipolaris sorokiniana (Sacc.) Shoemaker is more damaging than other diseases, causing major reduction in quality and grain yield of barley crop. This disease can be managed by repeated fungicide applications, however, deployment of resistant varieties still remains on the top priority. Out of the 262 barley entries screened for two consecutive years under artificial epiphytotic conditions, five entries consisting of four germplasm lines viz., BL-1309, BL-1313, BL-1532, BL-1562 and one variety PL-891 were resistant towards the disease whereas thirty-three entries and two hundred and eighteen entries exhibited moderately resistant and moderately susceptible reaction respectively. Disease score of more than 78 was recorded in six entries namely, BL-1500, BL-1540, BL-1542, BL-1576, BL-1652 and PL-426 (susceptible check), exhibiting susceptible reaction towards disease. Thus, the barley entries which are resistant to spot blotch disease under artificial inoculated conditions during two years of testing under field conditions can be utilized as donars by breeders to incorporate spot blotch resistance in good yielding cultivars, which are prior found to be susceptible to the disease.
