Screening of Barnyard Millet Germplasm against Shoot Fly and Stem Borer Damage under Field Conditions

introductory identification of resistant lines against the striped stem borer, chilo suppressalis (walker) under field conditions

in sustainable agriculture, using of resistant plants is one of the best methods for integrated pest management. resistance of 140 rice promising lines against striped stem borer was evaluated in two planting date in the field under natural infections in sari agricultural science and natural resources university during 2008-2009. this study carried out as a factorial experiment in randomized co...

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...

Evaluation of popcorn germplasm for resistance to pink stem borer

Antifeedants of Indian barnyard millet, Echinochloa frumentacea link, against brown planthopper, Nilaparvata lugens (Stål).

Eight compounds isolated from Indian barnyard millet have been identified as L-malic acid, trans-aconitic acid, (+)-isocitric acid, 5-O-caffeoylquinic acid, 4-O-caffeoylquinic acid, isocarlinoside, 2"-O-rhamnosylisoorientin, and 7-O-(2"-O-glucuronosyl)glucuronosyltricin, respectively. These compounds showed high antifeeding activity against brown planthopper only when they were combined.

Characterization and Field Performance of 15 Strawberry Germplasm under Bangladesh Conditions

Fifteen strawberry germplasm collected from local and exotic sources were evaluated for different qualitative and quantitative characters. The germplasm showed variation for majority of the studied traits. Plant height during peak harvest ranged from 14.67 to 25.00 cm and FA 007 exhibited the tallest plants. The maximum number of leaves plant was produced by FA 006 (46.67). The maximum number o...
