Reaction of land races of rice against major chewing pest of rice under saline conditions

Sheeba Joyce Roseleen S, Chitra K and C Gailce Leo Justin
Rice, (Oryza sativa L.) is a vulnerable crop to climate variability or climate change and presence of pest certainly affects the crop productivity. Among these factors, insect-pests contribute substantially to yield loss in rice production and productivity. Field trials were taken up during 2017-18 and 2018-19 at ADAC & RI, Tiruchirappalli with a view to study the reaction of landraces of rice against major chewing pest under saline conditions. Fourteen landraces were raised in samba season for two years and evaluated for their resistance following the IRRI Standard Evaluation System of Rating (SESR). Among the land races screened Kudavalai, Thengapoo samba, Kanba samba, and Kandha sala were found to be highly resistant and recorded no pest in both the years of study and can be potentially used as donar sources for breeding for insect resistance in rice. Thengapoo samba Kanba samba Kandha sala and Kandavali were highly resistant to Rice yellow stem borer while Kuruvikar, Seeraga samba, Karudan samba and Kaivara samba Seeraga samba, Kandasala, Karudan samba and Thegapoo samba were observed as highly resistant sources to Gall midge and Leaf folder, respectively.
