Leaf color mutations provide valuable genetic resources for elucidating the molecular regulatory mechanisms of plant growth and serve as efficient tools for screening offspring in crossbreeding. In this study, a Tartary buckwheat (Fagopyrum tataricum) mutant with yellow-green leaves (yl1) was isolated from 60Co-γ-radiation mutation bank. Compared to wild type (WT), yl1 showed similar biomass and yield

Short-term soil carbon mineralization on golf course sand-based putting green and its effect on creeping bentgrass nitrogen uptake Crop Sci. (IF 2.3) Pub Date : 2023-12-15 Qiyu Zhou, Douglas J. Soldat, Matthew D. Ruark
A rapid soil test for accurately estimating nitrogen (N) supply from soil organic matter would help turfgrass managers develop N fertilization programs. In this study, we tested the feasibility of using a quick test, mineralizable carbon (min-C), to predict turfgrass growth and N uptake from sand-based putting green soils. A 2-year field experiment was conducted in Verona, WI, on four sand-based research

Evaluating breeding for broad versus narrow adaptation for cassava in Nigeria using stochastic simulation Crop Sci. (IF 2.3) Pub Date : 2023-12-14 Moshood A. Bakare, Siraj Ismail Kayondo, Peter Kulakow, Ismail Yusuf Rabbi, Jean-Luc Jannink
The cassava (Manihot esculenta Crantz) breeding program at the International Institute of Tropical Agriculture (IITA) has adopted genomic selection to accelerate genetic gain. The program continues to develop varieties broadly adapted across Nigeria's diverse agroclimatic zones. However, for this purpose, genotype-by-environment interaction (GEI) presents a challenge. To decide whether broad adaptation

Association of hard fescue (Festuca brevipila) stress tolerances with genome mapped markers Crop Sci. (IF 2.3) Pub Date : 2023-12-11 Bradley Bushman, Matthew Robbins, Yinjie Qiu, Eric Watkins, Andrew Hollman, Nicole Mihelich, Dominic Petrella, Florence Breullin-Sessoms, Ming-Yi Chou, Paul Koch
Hard fescue is an allo-hexaploid, caespitose, cool-season grass that is part of the fine-leaved ovina complex of the Lolium–Festuca clade in Poaceae. It is predominantly used as a low-maintenance turfgrass and soil stabilization grass in situations with reduced inputs of nitrogen and water. While often recommended for use under tree canopies, prolonged foliar shade can thin turf stands and reduce their

Multiple physiological mechanisms involved in reproduction could be targeted for breeding heat tolerance in lima bean Crop Sci. (IF 2.3) Pub Date : 2023-12-11 Emmalea G. Ernest, Randall J. Wisser
With global warming, the impact of high-temperature stress on crop production is one of the major issues facing agriculture. Combining a series of field and controlled environment experiments, the current study aimed at understanding causes of yield loss due to heat stress in lima bean (Phaseolus lunatus L.) in order to guide breeding for heat tolerance. A growth-stage analysis of multi-year field

A study of pod constriction in a peanut population with mixed wild and cultivated genetics Crop Sci. (IF 2.3) Pub Date : 2023-12-11 Carolina Ballén-Taborda, Namrata Maharjan, Mark Hopkins, Larissa Arrais Guimarães, Duncan Lindsey, David J. Bertioli, Soraya C. M. Leal-Bertioli
Wild relatives comprise a diverse genetic source from which to introduce beneficial alleles for peanut breeding. However, when using wild species for breeding, unadapted agronomic characteristics are often co-inherited along with favorable traits. Previously, an advanced backcross population was developed from a cross between Arachis hypogaea and the wild-derived induced allotetraploid (Arachis batizocoi

Application of humic acid increases the economic value and yield of superior tobacco as well as improves the chemical and processing quality Crop Sci. (IF 2.3) Pub Date : 2023-12-10 Yi Pu, Jiangzhou Li, Kuai Dai, Xinghui Gu, Meiju Liu, Qinglin Ji, Ziwang Zhou, Changhua Zhao, Limeng Zhang, Shan Lin
The overuse of nitrogen (N) fertilizer in the vegetable growing season leads to a high amount of soil residual N and a decrease of resistance to tobacco disease in the vegetable–tobacco continuous cultivation system, which will seriously threaten the sustainable development of tobacco production. Humic acid (HA) rich in bioactive substances and microelements may enhance leaf growth rate and improve

Comparative physiological and transcriptomic analysis of two contrasting soybean genotypes reveals complex mechanisms involved in drought avoidance Crop Sci. (IF 2.3) Pub Date : 2023-12-10 Shengyou Li, Chunjuan Yan, Yongqiang Cao, Changling Wang, Xugang Sun, Lijun Zhang, Wenbin Wang, Shuhong Song
To overcome drought stress in soybean (Glycine max), it is strategically vital to improve drought resistance. Yet, the underlying molecular mechanisms responsible for drought resistance remain poorly defined. Here, we present comparative physiological and transcriptome analyses in seedlings of two contrasting genotypes, drought-resistant (DR) L14 and drought-sensitive (DS) L21 in response to polyethylene
