The fortification of cereal grains with metal micronutrients is a major target to combat human malnutrition of Fe and Zn. Based on recent studies showing that N fertilization can promote Fe and Zn accumulation in cereal grains, we investigated here the influence of nitrate- or ammonium-based N fertilization on the accumulation of Fe, Zn, and Cu as well as metal chelator pools in flag leaves and...

Growth at elevated CO2 often decreases photosynthetic capacity (acclimation) and leaf N concentrations. Lower-shaded canopy leaves may undergo both CO2 and shade acclimation. The relationship of acclimatory responses of flag and lower-shaded canopy leaves of wheat (Triticum aestivum L.) to the N content, and possible factors affecting N gain and distribution within the plant were investigated i...

Abstract: A doubled haploid (DH) population, which consists of 120 lines derived from anther culture of a typical indica and japonica hybrid ‘CJ06’/‘TN1’, was used in this study. Ligule lengths of flag leaf were investigated for QTL mapping using the DH population. Five QTLs (qLL-2, qLL-4, qLL-6, qLL-10 and qLL-12) controlling the ligule length (LL) were detected on chromosome 2, 4, 6, 10 and 1...

Genetic diversity in 40 traditional boro rice genotypes was studied under irrigated condition through Mahalanobis D 2 statistic for grain yield and yield contributing characters. The genotypes were grouped into five clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the clusters. The intra-cluster distances were lower in all t...

The results indicated that the seed yield per plant showed a significant positive correlation with most of traits like days to 50% flowering, height, filled grains panicle, number spikelet fertility, flag leaf width, numbers tillers plant, effective panicle length and 100 weight, representing importance these for development great yielding varieties in contrast trait sterility has been reported...

In monocarpic species, during the reproductive stage the growing grains represent a strong sink for nitrogen (N) and trigger N remobilization from the vegetative organs, which decreases canopy photosynthesis and accelerates leaf senescence. The spatiotemporal distribution of N in a reproductive canopy has not been described in detail. Here, we investigated the role of the local light environmen...

The aim of this study was to figure out genetic variability, correlation and path co-coefficients for seven traits in 42 F3 families the cross Azucena/CB 87R*1 aimed developing new restorer lines with indica tropical japonica background their utilization a hybrid program. population exhibited high PCV  GCV  viz., number productive tillers per plant, panicle weight single plant yield. ...
