The extreme climate of the Canadian Prairies poses a major challenge to improve yield. Although it is possible to breed for yield per se, focusing on yield-related traits could be advantageous because of their simpler genetic architecture. The Canadian flax core collection of 390 accessions was genotyped with 464 simple sequence repeat markers, and phenotypic data for nine agronomic traits incl...

some parts of semitropical regions in khouzestan, fars, kohgiloyieh-va-boyrahmad, lorestan, golestan, ardabil, kermanshah and boushehr provinces specified to spring barley cultivation which local or a few improved cultivars are grown there. barley breeding activities in dryland agricultural research institute(dari) are continuously undertaken in gachsaran, kouhdasht, gonbad and moghan to introd...

Plant architecture traits are closely related to plant biomass, lodging, and photosynthetic efficiency, which in turn affect soybean yield. In this study, we investigated a Chinese mini core collection consisting of 224 germplasm accessions for four architecture-related (plant height (PH), number nodes on main stem (NN), branch (BN), diameter (DI)) under three environments conducted genome-wide...

Lodging is a major constraint to increasing the global productivity of maize (Zea Maize L.). The objectives this paper are to: i) describe model for stem and root lodging in maize, ii) calibrate anchorage strength component model, iii) evaluate model’s applicability by assessing its capacity explain effects crop husbandry on risk iv) investigate potential further develop predict at an early eno...

In plants, investment in height improves access to light, but incurs costs in construction and maintenance of the stem. Because the benefits of plant height depend on which other height strategies are present, competition for light can usefully be framed as a game-theoretic problem. The vertical structure of the world’s vegetation, which is inefficient for plant growth, can then be understood a...

Crop monitoring is important in precision agriculture. Estimating above-ground biomass helps to monitor crop vitality and to predict yield. In this study, we estimated fresh and dry biomass on a summer barley test site with 18 cultivars and two nitrogen (N)-treatments using the plant height (PH) from crop surface models (CSMs). The superhigh resolution, multi-temporal (1 cm/pixel) CSMs were der...

Plant height of maize is related to lodging resistance and yield highly heritable but also polygenic, thus an important trait in breeding. Various manual methods exist determine the plant maize, yet they are labor-intensive time consuming. Therefore, we established digital surface models (DSM) based on RGB-images captured by unmanned aerial vehicle (UAV) at five different dates throughout growt...

five genotypes of chickpea as a half diallel crossed with each other, in 2008, 5 parents and 10 progenies were planted as randomized complete block design and some traits including days to podding, basal pod height, number of pods per plant, number of double seed pods per plant, number of single seed pods per plant, number of empty pods per plant, seeds per plant and seed yield per plant were e...

irrigated barley is grown on about 50,000 hectares in the warm agro-climate zone in the south of iran. the average grain yield of barley in these areas is 2,000 kg/ha. wide adaptability and high grain yield stability are important assets for barley varieties to be grown by farmers. zahak barley cultivar was initially selected from international barley germplasm received from cymmit and based on...
