Genetic improvement has been devoted to increasing rice yield by the spikelet number per panicle and spikelet/leaf ratio. As a result, indica-japonica hybrid “Yongyou” varieties with large panicles superhigh potential have developed. These exhibit significantly higher grain nitrogen use efficiency for (NUEg) under moderate high N supply conditions due their sink size, but performance remains ob...

To determine the combining effects of nitrogen application rate and planting density on rice yield grain quality formation under salinity conditions, a field experiment was conducted in coastal saline area using Oryza sativa L. cv. Nangeng 9108 from 2019 to 2020. The designed with six rates (0, 210, 255, 300, 345, 390 kg ha−1; denoted as N0-N390, respectively) two transplanting densities (334,0...

Agropyron cristatum (L.) Gaertn. (2n = 4x = 28, PPPP), a wild relative of common wheat, possesses many potentially valuable genes for wheat breeding. To transfer these genes into wheat, a series of wheat-A. cristatum derivatives have been obtained in our laboratory. In this study, a wheat-A. cristatum derivative II-3-1 was obtained, which was proven to contain a 1P (1A) disomic substitution and...

Abstract Background Wheat spike architecture is a key determinant of multiple grain yield components and detailed examination morphometric traits beneficial to explain wheat the effects differing agronomy genetics. However, quantification has been very limited because it relies on time-consuming manual measurements. Results In this study, using X-ray Computed Tomography imaging, we proposed met...

Cluster analysis is a type of exploratory that used for classifying unknown individuals into groups members share certain similarity. Grouping breeding materials different clusters based on their performances under given condition allows plant breeders to select lines more efficiently. This study aimed group performance water stress conditions using cluster analysis. The experiment was conducte...
