Harvest weed seed control (HWSC) systems have been introduced as an alternative weed control technology for use at a novel weed control timing in grain production systems. The inclusion of HWSC in weed control programs has likely greatly contributed to lower weed densities, mitigating the impact of herbicide resistance and slowing further evolution of resistance. The successful use of HWSC by Australian grain growers has attracted global interest in developing this weed control approach for the world’s cropping systems.

CP21645Agronomic assessment of the durum Rht18 dwarfing gene in bread wheat

G. J. Rebetzke 0000-0001-7404-0046, A. R. Rattey, W. D. Bovill, R. A. Richards, B. J. Brooks and M. Ellis
pp. 325-336

Poor establishment associated with the Green Revolution dwarfing genes will reduce grain yields in future changing climates. A global survey has highlighted that the durum Rht18 dwarfing gene offers an option for breeders wanting improved wheat establishment and early growth when deep sowing. We report on reduced height and increased yield potential, and greater early vigour in bread wheat genotypes bred from the original Rht18 durum wheat variety Icaro.

CP21500Imaging-based screening of wheat seed characteristics towards distinguishing drought-responsive Iranian landraces and cultivars

Ehsan Rabieyan, Mohammad Reza Bihamta 0000-0003-0614-0963, Mohsen Esmaeilzadeh Moghaddam, Valiollah Mohammadi and Hadi Alipour
pp. 337-355

Imaging-based screening provides an opportunity for more exact/rapid analysis of seed traits. This study, therefore, was focused on evaluating the phenotypic diversity of wheat seeds under rain-fed and well-watered conditions by using image analysis and permitted the formation of a morphometric seed database of Iranian wheat genotypes. These findings would be helpful for preserving the wheat genetic diversity against drought stress.

CP21410Improvement of grain yield under moisture and heat stress conditions through marker-assisted pedigree breeding in rice (Oryza sativa L.)

pp. 356-369

We used marker-assisted pedigree breeding to pyramid QTLs governing yield under moisture stress, water-use efficiency and heat tolerance with QTLs for yield traits. We identified 14 pyramided lines with various combinations of 5–11 targeted QTLs and observed substantial yield advantage in the pyramided lines. We demonstrate that the systematic combination of important QTLs through marker-assisted pedigree breeding is an outstanding approach to supplement conventional pedigree breeding, especially to improve complex abiotic stress tolerance besides yield enhancement.

CP21563Effects of multi-growth stage water deficit and orthosilicic acid fertiliser on lodging resistance of rice cultivars

Solomon O. Olagunju 0000-0001-7429-5030, Muftau O. Atayese, Olalekan S. Sakariyawo and Enoch O. Dare
pp. 370-389

Water deficit can predispose rice to lodging yet the effect of water deficit on lodging has been less studied. Orthosilicic acid (OSA) fertiliser has potential to increase the mechanical strength of stems and minimise water loss from plant leaves. Six rice cultivars, including Moroberekan, were subjected to multiple growth stage water deficits. Vegetative plus reproductive stage stresses impacted greatly on lodging traits while OSA fertiliser increased the lodging resistance through deposition of a mechanical layer in the inner wall of stems.

CP21158Seedball technology enhances pearl millet yield in a Sahelian subsistence production system

Charles I. Nwankwo 0000-0002-5552-9900, Hannatou M. Oumarou, Maman Nouri, Ali M. Aminou and Ludger Herrmann
pp. 390-400

Pearl millet is a staple crop in the Sahel, but its panicle yield is low because of poor seedling establishment arising from low-nutrient soils. Lack of skills and finance deny the local farmers access to already existing technologies such as seed treatments and mineral fertilisation. Our work shows the seedball technology, which is simple and based on local materials, increases pearl millet panicle yield by ∼30% in the Sahel.


This review article elaborates on the nutritional constituents, antinutritional factors, health benefits and treatment of diseases using Cicer arietinum L. (chickpea) and its components. The health benefits of consuming chickpea, like antimicrobial, antioxidant, anti-inflammatory properties, its potential as nutraceuticals, prebiotic food, the recent advances in the use of chickpea derivatives for the treatment of diseases like diabetes, hypercholesterolemia, hepatotoxicity and cancer are discussed elaborately. This review lays out a framework for understanding plant protein and its benefits beyond nutrition.

CP21331Development and validation of microsatellite markers for kikuyu grass using next generation sequencing technology

Juliana Arango 0000-0002-4623-4588, Albeiro López, Edna Márquez and Julián Echeverri
pp. 415-424

Genetic variability studies of a species generate new knowledge about genotypes with greater productive potential, providing the basis for the design of genetic improvement programs. Kikuyu grass is one of the most widely used grasses for forage feeding in dairy regions. These microsatellite loci help complement the information on the genetic structure of the kikuyu populations and will be useful for the characterisation and evaluation of the diversity of germplasm in other parts of the world.
