Rice yield is a complex trait that strongly affected by environment and genotype × interaction (GEI) effects. Consideration of GEI in diverse environments facilitates the accurate identification optimal genotypes with high performance, which are adaptable to specific or environments. In this study, multiple trials were conducted evaluate grain (GY) four yield-component traits: panicle length, n...

To meet the increasing raw material demand of livestock and food sectors in our country is a need for new high-quality barley varieties that have short vegetation period, resistance to lodging, homogeneous plump grain, high grain biomass yield, compatible with climate Central Anatolia Region. this need, it was aimed determine appropriate lines by comparing 18 advanced belonging Transitional Zon...

Abstract Long grain geng/japonica rice has a higher market preference due its excellent appearance quality. The dense and erect-panicle 1 ( dep1 ) gene been widely used in the breeding of high-yielding cultivars China. However, this causes short round shape thus making it less attractive global markets. Therefore, long-grain by incorporating with major-effect is high priority industry. Up to no...

This paper aims to explore issues related destruction of soil nutrients and structure in a rice-wheat double-cropping area caused by over-tillage prior rice cultivation. A three-year cycle rotation tillage pattern (RT), consisting “no-tillage–no-tillage–plough”, with straw-returning direct rice-seeding technology, was designed tested, compared continuous no-tillage (CN) conventional ploughing &...

Observational studies consistently find an inverse relationship between whole-grain intake and weight gain. We aimed to confirm this in an open-label researcher-blinded parallel design randomised trial. A total of 179 overweight/obese women with a habitually low whole-grain intake (<16 g/day) were randomised to a weight maintenance diet with refined-grain (RG) or whole-grain (WG) foods (80 g/da...

in order to determine the best index for evaluating maize genotypes, 15 maize inbred lines were evaluated in two planting dates, 6 july to coincide heat stress with pollination time and 27 july as normal planting to avoid high temperature during pollination and grain filling period, using a randomized complete block design with three replications, in shushtar city, in 2007. result showed that i...

Sorghum [Sorghum bicolor (L.) Moench] yield formation is severely affected by high temperature stress during reproductive stages. This study pursues to (i) identify the growth stage(s) most sensitive to high temperature stress during reproductive development, (ii) determine threshold temperature and duration of high temperature stress that decreases floret fertility and individual grain weight,...

Crown rust, caused by the fungal pathogen, Puccinia coronata Corda var. avenae W.P. Fraser Ledingham, reduces kernel quality and grain yield in oat (Avena sativa L.). Partial resistance is considered to be a durable form of rust resistance. This study sought to evaluate the feasibility of simultaneously improving partial resistance to crown rust, grain yield, and seed weight in an oat populatio...

Heading date and grain weight are two determining agronomic traits of crop yield. To date, molecular factors controlling both heading date and grain weight have not been identified. Here we report the isolation of a hemizygous mutation, heading and grain weight (hgw), which delays heading and reduces grain weight in rice. Analysis of hgw mutant phenotypes indicate that the hemizygous hgw mutati...
