Using time-related phenotypic data, methods of composite interval mapping and multiple-trait composite interval mapping based on least squares were applied to map quantitative trait loci (QTL) underlying the development of tiller number in rice. A recombinant inbred population and a corresponding saturated molecular marker linkage map were constructed for the study. Tiller number was recorded e...

In order to distinguish ourselves from competitive pack , its becoming increasing important to seek a deeper understanding of value driving customer needs during early stages of product process development. QFD techniques and its many advanced versions can be used for it. This article aims to appraise the feasibility of Total Quality Function Deployment (TQFD) by conducting a case study in a tr...

A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...

Tiller number, an important growth parameter for rice cultivation, is still being assessed manually. This work investigated the influence of dataset composition on performance deep learning models tiller number estimation in rice. Four datasets were constructed early tillering, active and maximum tillering by applying concepts mixed varieties, class balance, data augmentation. YOLOv4 trained to...

Since many of the quantitative plant characters of economic values are highly influenced by environmental condition, the progress in breeding in such a population is primarily conditioned by the magnitude, nature and inter-relations of genotypic and non-genotypic variations in plant characters. Therefore we estimated phenotypic, genotypic and environmental correlation coefficients and path coef...

Abstract Background Tiller number is a factor determining panicle and grain yield in wheat ( Triticum aestivum ). Auxin plays an important role the regulation of branch production. PIN-FORMED 1 (PIN1), auxin efflux carrier, tiller rice Oryza sativa ); however, little known on roles PIN1 wheat. Results Nine homologs TaPIN1 genes were identified wheat, which TaPIN1-6 showed higher expression stem...

Proper branching and successful reproductive growth is of great importance for rice productivity. Substantial progress has been made in uncovering the molecular mechanisms underlying tillering control and spikelet sterility. However, rice tillering is developmentally controlled, and how it is regulated coordinately with reproductive growth remains unclear. This study characterized a rice mutant...

根深ネギの晩抽性遺伝資源，晩ネギの分げつ性に関する遺伝解析のため，はじめに14品種・系統を用いて分げつ数と諸形質の相関分析を行った．相関分析の結果より，‘分げつ数’は‘開花日’と有意な相関が見られず，分げつ性と晩抽性は独立して選抜できる可能性が示唆された．次に相関分析での‘分げつ数’の多少および‘開花日’の早晩について変異が大きくなるように6品種・系統を選定し，片側ダイアレル分析を実施した．解析集団は生育段階に応じて3回分げつ数を調査した．片側ダイアレル分散分析の結果，全調査回で相加効果を示すa項のF値がb項を大きく上回ったこと，平均優性度が1以下であったことから，分げつ数は相加効果が大きい不完全優性の形質であると推定された．また優性遺伝子の平均的作用方向は分げつ数の少ない方向と考えられた．3回の分げつ数調査およびダイアレル分析結果を比較すると，親系統の優性順序，親系統の優性および劣...
