Sorghum (Sorghum bicolor (L.) Moench) is a drought-resistant crop and an important food resource in terms of nutritional as well as social-economic values, especially in semi-arid environments. Cultivar selection and processing methods have been observed to impact on composition and functional and nutritional value of sorghum. Amino acid imbalance, cyanogenic glycosides, endogenous anti-nutrien...

Breeders normally select simultaneously for several traits in various environments. We investigated the effects of the progeny x environment interaction on success in selection for several traits. The population used was obtained from a cross between the CVIII-85-11 line, which has a semi-erect to prostrate plant architecture and a cream with brown streaks bean type, and the BRS-Supremo cultiva...

introduction the lentil or masoor (lens culinaris l.) is a brushy annual plant of the legume family, grown for its lens-shaped seeds. lentil has been one of the first crops domesticated in the near east. with 26% protein, lentil is the vegetable with the highest level of protein other than soybeans, and it is an important part of people’s diet in many parts of the world. it is reported that the...

Temperature and photoperiod can be used to simulate soybean (Glycine max [L.] Merr) phenology because they serve as surrogates for complex biochemical pathways leading to the appearance of certain developmental stages at the whole plant level. We developed a soybean phenology model (SOYDEV) which utilizes non-linear temperature and photoperiod functions and separates floral induction and post-i...

In order to determine the effects of nitrogen fertilizer on grain quality and starch physicochemical properties japonica rice cultivars with different contents amylose, normal amylose content (NAC) low (LAC) were grown in a field, or without (WN). The relationships between content, eating also examined. Compared WN, (NF) significantly increased yield but markedly decreased weight. addition, pro...

This work describes the development of a fast and efficient methodology for Agrobacterium tumefaciens-mediated genetic transformation of internodal stem segments from potato (Solanum tuberosum L.), cultivar Désirée, using phosphinothricin (PPT, glufosinate ammonium) as a selection agent. This methodology has a transformation efficiency of 68%, inducing shoots after 4 to 5 weeks in the presence ...

Optimizing cellulosic ethanol yield depends strongly on understanding the biological variation of feedstocks. Our objective was to study variation in capacity for producing fermentable sugars from straw of winter wheat cultivars with a high-throughput pretreatment and hydrolysis well-plate technique. This technique enabled us to estimate cultivarrelated and environmental correlations between su...

Abstract The objective of this work was to identify environmental factors with significant effects on the genotype by environment interaction (GEI) sugarcane, and generate thematic maps yield adaptability genotypes for state Goiás, Brazil, through integrated use factorial regression models geographic information system (GIS). study based recoverable sugar (YRS) from cultivar field trials carrie...

white been line wa8592-1 was first introduced in iran through the yield trail nurseries received fron ciat in 1991. in observation nurseries carried out during 1992 and 1993 cropping seasons, ten bean populations were evaluated for yield and other characteristics, and 60 lines were selected. preliminary and advanced yield trails carried out for six years (1995-2000) in four locations khomein, e...

The development of resistant cultivars is one the strategies applied in pest control. method has advantages reduced cost and lack unwanted effects on environment. Over past decades, significant effort been made toward developing natural maize resistance to pests by evaluating germplasm cultivar selection. This review highlights a breeding program, potential, advances, challenges addressing thes...
