Abstract:

Fifteen genotypes of barley were screened for their comparative resistance to aphid, R. maidis in Rabi 2014-15 at the Agronomy farm of SKN College of Agriculture, Sri Karan Narendra Agriculture University, Jobner (Rajasthan). The mean aphid population of all the observations ranged from 19.86 to 49.56 aphids per tiller. The minimum mean aphid population was found on genotype, RD-2035 (19.86 aphids/ tiller) followed by RD-2552 (22.41 aphids/ tiller), RD-2849 (24.74 aphids/ tiller) and RD-2794 (25.84 aphid/ tiller), these were differed non-significantly in their degree of infestation each other and differed significantly over rest of the genotypes. The maximum mean aphid population was found on genotype, RD-2624 (49.56 aphids/ tiller) followed by RD-2052 (48.97 aphids/ tiller), these were statistically at par with each other in their degree of infestation. The genotypes viz., RD-2035, RD-2552 and RD-2794 were found as least susceptible; RD-2503, RD-2508, RD-2793, PL-426, RD-2592, RD-2660, RD-2668, RD-2715 and RD-2786 and RD-2849 as moderately susceptible; whereas, RD-2052 and RD-2624 as highly susceptible.
