Genetic basis of maize stalk strength decoded via linkage and association mapping

The Plant Journal, 2023
SUMMARYStalk lodging is a severe problem that limits maize production worldwide, although little attention has been given to its genetic basis. Here we measured rind penetrometer resistance (RPR), an effective index for stalk lodging, in a multi‐parent population of 1948 recombinant inbred lines (RILs) and an association population of 508 inbred lines (

Spatial accumulation of lignin monomers and cellulose underlying stalk strength in maize

Plant Physiology and Biochemistry
Lodging largely affects yield, quality and mechanical harvesting of maize. Stalk strength is one of the major factors that affect maize lodging. Although plant cell wall components including lignin and cellulose were known to be associated with stalk strength and lodging resistance, spatial accumulation of specific lignin monomers and cellulose in ...

Ultimate Strength of Green Burley Tobacco Stalk Material

Transactions of the ASAE, 1992
Ultimate strength of the xylem layer of the burley tobacco stalk ranged from 674 to 1453 kPa in tension and 1284 to 1943 kPa in shear. The ASTM standards for testing wood were used since the xylem layer has a structure similar to wood but were altered to meet the physical constraints of the stalk.

Competing Effects of Buckling and Anchorage Strength on Optimal Wheat Stalk Geometry

Journal of Biomechanical Engineering, 2002
Abstract We seek the ideal wheat stalk, which minimizes the structural mass required to support a fixed grain load in the presence of gravity and wind. The optimization search is restricted to stepped cylindrical stems of known moduli and density but unknown dimension.

Chemical and in Vitro Digestible Dry Matter Composition of Maize Stalks after Selection for Stalk Strength and Stalk‐Rot Resistance¹

Crop Science, 1986
Although maize (Zea mays L.) is a major forage crop, little attention has been given to possible alteration of forage quality associated with breeding for increased resistance to stalk lodging. This study was designed to evaluate changes in stalk composition and digestibility resulting from three cycles of recurrent selection each for improved stalk ...

Effect of Prolificacy on Grain Yield and Root and Stalk Strength in Maize

Crop Science, 1988
Poor root and stalk strength have contributed to limited use of prolific maize (Zea mays L.) hybrids by farmers. Knowledge of the relationships of yield, prolificacy, and plant standability permits appropriate emphasis in selection programs. Three prolific maize populations and one nonprolific hybrid (B73 ✕ Mo17) were grown a randomized complete block ...

Mechanical strength testing of stalk materials and compacting energy evaluation

Industrial Crops and Products, 2000
Abstract The great potential of cereal lignocelluloses for use as energy or as an industrial raw material source determines the necessity to investigate the mechanical properties of stalks, as the main parts of any herbaceous material. Annual world production of cereal straw is approximately of the same amount (around 2 billion tons) as wood material

QTL mapping of stalk bending strength in a recombinant inbred line maize population

Theoretical and Applied Genetics, 2013
Stalk bending strength (SBS) is a reliable indicator for evaluating stalk lodging resistance of maize plants. Based on biomechanical considerations, the maximum load exerted to breaking (F max), the breaking moment (M max) and critical stress (σ max) are three important parameters to characterize SBS.

Effect of Recurrent Selection for Stalk Crushing Strength on Agronomic Characteristics and Soluble Stalk Solids in Maize¹

Crop Science, 1984
Our objectives were to determine responses to selection for crushing strength and the associated changes in yield, stalk strength, field stalk lodging, flowering dates, and soluble stalk solids. The MoSQA and MoSQB maize (Zea mays L.) synthetics that had undergone five cycles of recurrent selection for high and low stalk crushing strength were used ...
