The concept of a linear increase in harvest index, dHI/dt, has proven very useful for crop simulation modeling. The effect of high temperature on the response of dHI/dt of pods and seeds of peanut (Arachis hypogaea L.) has not been describe...
Genetic Improvement in Short-Season Soybeans: II. Nitrogen Accumulation, Remobilization, and Partitioning [0.03%]
短季大豆遗传改良研究(II)——氮素积累、再利用与分配特性

S. Kumudini
Genetic improvement in yield is conditional on surmounting yield-limiting factors. Nitrogen (N) has been considered an important limiting factor to soybean [Glycine max (L.) Merr.] yield. The high demand for N by soybean seed was previously...
Implications of Atmospheric and Climatic Change for Crop Yield and Water Use Efficiency [0.03%]
大气和气候变迁对作物产量及用水效率的影响

Yield of water-limited crops is determined by crop water use and by plant water use efficiency, each of which will be affected by the anticipated rise in atmospheric carbon dioxide (CO(2)) concentration and concomitant increase in temperatu...

Greater yield per unit rainfall is one of the most important challenges in dryland agriculture. Improving intrinsic water-use efficiency (W(T)), the ratio of CO(2) assimilation rate to transpiration rate at the stomata, may be one means of ...
Breeding Opportunities for Increasing the Efficiency of Water Use and Crop Yield in Temperate Cereals [0.03%]

Genetic advances in grain yield under rainfed conditions have been achieved by empirical breeding methods. Progress is slowed, however, by large genotype x season and genotype x location interactions arising from unpredictable rainfall, whi...
Field Evaluation of Transgenic and Classical Sources of Wheat streak mosaic virus Resistance [0.03%]

G. L. Sharp et al.
The development of wheat (Triticum aestivum L.) cultivars that are resistant to Wheat streak mosaic virus (WSMV), yet competitive in yield under nondiseased conditions, is an objective for breeding programs in the Great Plains. This field s...
Enhancement of Seedling Emergence in Sweet Corn by Marker-Assisted Backcrossing of Beneficial QTL [0.03%]

Seedling emergence is an important trait that can limit commercialization of sweet corn hybrids. This study was designed to test what effect beneficial QTL alleles that enhance seedling emergence exert when introgressed, using marker-assist...
Characterization of SMV Resistance Genes in Tousan 140 and Hourei Soybean [0.03%]
桃香140和北荣大豆中的SMV抗病基因的鉴定

I. Gunduz et al.
'Tousan 140' and 'Hourei', two soybean [Glycine max (L) Merr.] accessions from Japan, each possess a single gene at different loci for resistance to Japanese Soybean mosaic virus (SMV) strain SMV C. However, more genetic information is need...
