Abstract/Contents: | "Buffalograsses, BuchloĆ« dactyloides (Nuttall) Engelmann, were evaluated under greenhouse culture for resistance to the Rhodesgrass mealybug (RGM), Antoninis graminis Maskel. Among 76 entries, four genotypes, TTU-58B, TTU-86A, TTU-94A and TTU-223A, had mean infestations ā¤ 0.22 mealybugs per 6.4 cm diam plant. TTU-86A and TTU-94A are tetraploids while TTU-58B and TTU-223A are hexaploids. An additional five hexaploid genotypes were infested with ā¤ 1 mealybug per plant. However, FH-5, a diploid, had a moderate infestation rate but exhibited the lowest damage ratting of 1.78 (scale of 1 to 5, where 1 = little or no damage) among all the test entries. Two genotypes, TTU-35 and TTU-115 were the most susceptible entries with the highest infestation rate of > 21 RGM per plant; these entries were also hexaploids. Several other diploid and tetraploid genotypes were also evaluated, but did not provide resistance." |
