Abstract

The growth and productivity of foxtail millet is affected by many diseases. Among those disease, foxtail millet blast, (Pyricularia setaria) which is also known as leaf spot is responsible for the economic loss up to 40% during congenial weather conditions, and it can be well managed through host plant resistance. The present research work has been carried out to assess blast resistant genotypes of foxtail millet under field conditions, a total ninety-three genotypes where evaluated in three replications at breeding farm, Rajmata Vijayaraje Scindia Agricultural University, Gwalior, Madhya Pradesh, India during Kharif 2020-21 and 2021-22. A wide variation in response to blast where seen, as their PDI varied significantly, none of the entries was found highly susceptible, twenty three genotypes where found highly resistant, as their blast severity PDI was recorded less 11.11%. The maximum PDI range 55.55% to 77.77 % was noted in foxtail- 946, 969, 983, 1000, 1354, 1603. The resistant genotypes identified in the present research may be used further to develop improved genotypes against blast, which can help to boost production and productivity of foxtail millet.

Conclusion

From the present investigation it is concluded that twenty three genotypes where analyzed as highly resistant viz., foxtail-49, 96, 132, 160, 200, 237, 267, 295, 362, 364, 663, 717, 774, 784, 838, 936, 1013, 1037, 1137, 1162, 1665, 1725, Check SIA -3156.
