The wheat Green Revolution Rht-B1b and Rht-D1b dwarfing alleles are associated with increased grain yields but also reduced early growth seedling emergence, especially if sowing conditions unfavourable. gibberellic acid-responsive, mutagen-derived Rht18 gene was backcrossed from durum (Triticum turgidum subsp. L.) cv. Icaro into tall bread aestivum Halberd using phenotypic selection for plant h...

Lodging is one of the most important factors that affect wheat final yield. Emmer [Triticum turgidum subsp. dicoccum (Schrank ex Schübl.) Thell.] a likely gene source to improve durum [T. L. (Desf.) Husn.]; however, it highly susceptible lodging. The genetic studies traits related lodging in crosses × emmer remains largely understudied. Here, we used progenies (six generations) derived from two...

BACKGROUND The harvest index for many crops can be improved through introduction of dwarf stature to increase lodging resistance, combined with early maturity. The inbred line Shen5003 has been widely used in maize breeding in China as a key donor line for the dwarf trait. Also, one major quantitative trait locus (QTL) controlling plant height has been identified in bin 5.05-5.06, across severa...

creased by 22.5% over five cycles of selection for high RPR in MoSCSSS. The correlation between RPR and The rind penetrometer is an effective tool for measuring stalk EH is of interest in terms of direct vs. indirect selection strength in an effort to improve maize (Zea mays L.) germplasm for stalk lodging resistance. However, previous studies have indicated a for stalk strength. That is, to wh...

Other SectionsAbstractA new Adzuki bean cultivar, ‘Hongmiin’, was developed from the cross between K204656 (Toyomidainagon) and SA9905 in 2008. Hongmiin showed prominent agronomical characteristics, such as high grain quality, lodging resistance, yield regional adaptation trials (RYT) conducted for four years 2017 to 2020. ‘Hongmiin’ is an early maturing variety, having a bright red seed coat, ...

In subtropical environments lodging occurs at all stages of the oat plant development, particularly after panicle extrusion, causing severe yield reduction. This study aimed to identify morphological, chemical, and anatomical characteristics stem associated with resistance on oats, which may be used select resistant genotypes. A set genotypes diverse response were grown in nine environments, co...

The use of growth regulators as a technique that can reduce plant height and thus strengthen stalks, which may be an option to eliminate or lodging, thereby avoiding crop loss. However, there is lack information on the subject. purpose this study was evaluate effect dose (0; 37.5; 75.0; 112.5 e 150.0 g ha-1 active ingredient) application times trinexapac-ethyl (sixth, seventh eighth leaves), in...

Increasing planting density is among the most effective ways to increase soybean yield, but high increases lodging risks in plants. To examine effects of shading on plant lodging, tall cultivar Heinong 48 (HN48) and dwarf Henong 60 (HN60), two cultivars with large height differences (approximately 40 cm), were selected, their internode lengths measured under different densities 2019 determine k...

Crop lodging reduces yield quantity and grain quality of cereal crops. Understanding seasonal variation in crop susceptibility enables risk assessments predictions associated losses. We demonstrate a novel remote sensing-based approach, using sparse field observations widely available synthetic aperture radar (SAR) satellite imagery, to map safety factor against root (SFA) wheat. SFA quantifies...

The use of fertilizer results in tall rice plants that are susceptible to lodging and results in reduced plant yields. In this study, using chromosome segment substitution lines, we identified an effective quantitative trait loci (QTL) for culm strength, which was designated STRONG CULM2 (SCM2). Positional cloning of the gene revealed that SCM2 was identical to ABERRANT PANICLE ORGANIZATION1 (A...
