Evaluation of Rice Promising Lines for Resistance to Striped Stem Borer in 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...

development of strategies of rice striped stem borer (chilo suppressalis walk) management in farmers, field in mazandaran province

rice is the world's most important food crop. to decrease the damage of  rice pests, development of insect pest management strategies in rice is necessary. biennial results for determination of a suitable method to control striped stem borer in rice showed that integration of two methods of control (biological and mechanical) is a feasible effort to reduce stem borer infestation. to assure...

Evaluation of popcorn germplasm for resistance to pink stem borer

development of striped stem borer (chilo suppressalis) management strategies in hybrid rice in mazandaran province

rice is among the most important food crops throughout the world. hybrid rice benefits from about a 30 percent yield advantage over the conventional pure line varieties and this phenomenon can play an important role in fighting world hunger. to diminish the damage of rice pests, development of insect pest management strategies in hybrid rice is necessary. this study was aimed at evaluating the ...

Evaluation of Qualitative Traits of Grain in Rice Promising Lines (Oryza Sativa L.)

The development and production of genotypes with high quality is one of the important purposes in the plant breeding programs. In order to evaluate the qualitative traits, 77 lines of rice (F12 generation) in comparison to five control cultivars (including Tarom­Mahalli, Sang-e-Tarom, Nok­Seyah, Fajr and Deilamani) were studied in the Biotechnology Laboratory of Sari Agricultural Sciences and N...
