Evaluation of Rice Promising Lines for Resistance to Striped Stem Borer in Field Conditions
In this study, the mechanism of resistance to striped stem borer was investigated in 10 rice genotypes and at different levels of nitrogen fertilizer. In addition, the relationship between some quantitative and qualitative traits of rice genotypes was evaluated with the resistance to striped stem borer.This experiment was conducted as split plot based on randomized complete block design with...
متن کاملEvaluation of Advanced GEM Lines for Multiple Insect Resistance and Fumonisin Concentration
PROJECT DESCRIPTION The overall objective of this project is the development of maize varieties with host plant resistance against the Western corn rootworm (WCR), the European corn borer (ECB), and Fusarium by searching for novel resistance genes and alleles available in GEM base populations. The breeding activities comprise intensive evaluation of GEM germplasm for multiple insect and Fusariu...
متن کاملBroadening Gene Pool of Rice for Resistance to Biotic Stresses Through Wide Hybridization
Variability in the cultivated germplasm for economic traits such as resistance to rice tungro virus, sheathblight, yellow stem borer, drought and salt tolerance is limited. This necessitated search for the genes in secondary and tertiary gene pool of genus Oryza. Fortunately, wild species are an important reservoir ofuseful genes for resistance to major disease, pest and tolerance t...
متن کاملEffect of Temperature on Developmental Rate of Sesamia cretica (Lepidoptera: Noctuidae) Immature Stages
Effect of temperature on development of pink stem borer, Sesamia cretica Lederer, was studied at eight constant temperatures (15, 18, 20.5, 24, 27, 30, 34, and 38°C), a photoperiod of 16:8 (L:D) h, and 50-60% rela\tive humidity. The larvae of pink stem borer were reared on cutting stems of maize. The results showed that temperature had statistically significant effect on developmental times of ...
متن کاملتاثیر منابع و مقادیر مختلف کود سیلیس بر رشد، عملکرد و میزان آلودگی به کرم ساقه خوار در رقم طارمهاشمی و لاین 843 در گیاه برنج
Silicon is as an essential element for crops and an important food source for the growth of rice plant. If no adequate replacement for this element, plants are faced with a shortage of silicon causing serious eating disorder and instability in plant resistance to pests. This research was done to investigate the effect of silicon on growth, yield and tolerance to rice stem borer in Tarom Hashemi...
