abstract
The study was conducted on 22 hybrids of maize i.e., NMH-589, NK-30, Rasi-4212, Super-36, IAHM-2013-12, HISHELL, Yashoda gold, Big boss, Don-1588, MM-2255, IAHM-2013-97, KMH-5-2020, 262(DKC-9154), Aditya-303, Laxmi-207, NMH-731, Raja ji, IAHM-2013-33, Rasi 359, IAHM-2013-11, IAHM-2013-09 and IAHM-2013-26 against maize pink stem borer Sesamia inferens (Walker) during Kharif 2014-2015. The results revealed significant differences among hybrids regarding Number of pin hole, leaf injury rating, dead hearts per cent and grain yield recording HISHELL lowest no of 13.07 pin holes, 2.70 leaf injury rating, 26.67 per cent dead hearts,0.40 exit holes plant-¹and maximum of 45.33 q ha-¹ grain yield proved to be the most tolerant variety. IAHM-2013-09 and IAHM-2013-26 with maximum number of pin holes 33.00 and 31.87, leaf injury rating plants-¹ 5.13 and 5.33, per cent dead hearts 66.67, exit holes 1.40 and 1.60 and minimum of 24.17 q ha-¹and 23.83 q ha-¹grain yields was rated as least tolerant.
