Photoperiod sensitivity in tropical maize accessions, early inbreds, and their crosses
… x tester interaction for genes controlling photoperiod. The six populations were: (1) Caingang (BOV 78) from Brazil; (2) Negro de Tierra Caliente (GUA 146) (NDTC-146) from Guatemala; (3) Lenha (RGS XX) from Brazil; (4) Negrito from Colombia; (5) Costeno (VEN 453) from Venezuela; and (6) …

Genetic control of flowering time and biomass yield in sorghum
… results suggest that the architecture of the photoperiod-sensitivity response differs between these two populations. Overall, our results suggest there is abundant genetic variation to quickly improve sorghum biomass yields by incorporating novel alleles from exotic sorghum.

Determining transpiration efficiency of eight grain sorghum lines [Sorghum bicolor (L.) Moench]
… difference, explaining the existence of photoperiod sensitivity among the sorghum genotypes. Assimilation (A), stomatal conductance (gs), and maximum quantum efficiency of photosystem II (Fv/Fm) were consistently greater for accession PI533946 (from India) and greater for accession …

The sustainability of tropical maize as an alternative biofuel or silage crop
… tropical by tropical) hybrid that retains the photoperiod sensitivity of tropical materials when grown in temperate regions, resulting in high biomass, but with delayed flowering that reduces or eliminates grain production. The reduced grain production results in accumulation of sucrose in the …

Physiological Traits and Quantitative Trait Loci Associated with Nitrogen Use Efficiency in Soft Red Winter Wheat
… 2D and 4A co-localized with known loci governing photoperiod sensitivity and resistance to Fusarium head blight (caused by the fungal pathogen Fusarium graminearum Schwabe), respectively. Three of the identified QTL (6A, 7A, and 7D) were associated with NUE in previous investigations, while the …

Biomass yield potential and nitrogen use efficiency of the photoperiod-sensitive energy sorghum
… and the environment. Four hybrids with different photoperiod-sensitivity (TX08001, TX17500, TX17600, TX17800) were studied for yield potential and N response under four N rates (0, 56, 112, 168 kg N ha-1) using aqueous urea ammonium nitrate (UAN: 32-0-0) in two locations (Urbana, IL and College …

Plant growth responses to winter climate change: from amongand within-species variation to plant-soil interactions
… several tree species and grass ecotypes the sensitivity to changes in photoperiod was found to influence the effect of temperature on growth cessation and resumption. Photoperiod sensitivity is therefore an important characteristic of plants related to the ability to extend the growing season …

GENETIC DISSECTION OF PINE1 CONTROLLED STEM ELONGATION AND NEW INSIGHTS INTO LONG DAY FLOWERING IN ORYZA SATIVA
… is limited and characterized by long day (LD) photoperiod. In the present study, we took advantage of a mutagenized Volano (a typical Italian rice variety) population to identify novel genes or alleles associated with the regulation of flowering time in LD. MutMap is a rapid gene identification …

Adaptation of wheat to a tropical environment
… differences in flowering time were related to photoperiod sensitivity and intrinsic earliness among varieties. The results suggested that early maturing varieties (eg. Axe) developed very rapidly which may limit their yield potential. In the field trials on Lombok, wheat productivity was …
