Agronomic and Quality Characteristics of High-Yielding Rice Lines

shiroudi, a new high yielding and good quality rice cultivar

in order to develop a high yielding rice cultivar with optimum cooking quality, a cross was conducted between two rice cultivars khazar, high yielding and resistant to blast disease and daylamani tarom, with good cooking quality in 1990. forty pure lines were selected and compared for high grain yield in 1996. ten selected lines together with two check cultivars dasht and onda were tested in ad...

Alternate wetting and drying in high yielding direct-seeded rice systems accomplishes multiple environmental and agronomic objectives

Rice (Oryza sativa L.) cultivation is critically important for global food security, yet it also represents a significant fraction of agricultural greenhouse gas (GHG) emissions and water resource use. Alternate wetting and drying (AWD) of rice fields has been shown to reduce both methane (CH4) emissions and water use, but its effect on grain yield is variable. In this three-year study we measu...

introduction of new high yielding and good quality rice cultivar, fajr

introduction of high yielding as well as high quality rice cultivars is one of the most important activities at rice research institute of iran (rrii). in 1991, 210 rice lines introduced from international rice research institute (irri) to rice research institute of iran were evaluated in observational and statistical experiments in mazandaran for two years, and seven lines were selected. these...

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
