Crop breeding must achieve higher rates of genetic gain in grain yield (GY) and yield stability to meet future food demands in a changing climate. Optimal contributions selection (OCS) based on an index of key economic traits should increase the rate of genetic gain while minimising population inbreeding. Here we apply OCS in a global spring oilsee...

We designed and validated a new multiplex PCR marker which discriminates between four insertion/deletion (INDEL) alleles in the 5' regulatory region of a major flowering time gene in Lupinus angustifolius, LanFTc1. The four INDEL alleles were the wild-type allele (ku) in variety Geebung (G), a 1208-bp deletion allele in accession P22660 (P), a 1423...

Common bean (Phaseolus vulgaris L.) is important in African diets for protein, iron (Fe), and zinc (Zn), but traditional cultivars have long cooking time (CKT), which increases the time, energy, and health costs of cooking. Genomic selection was used to predict genomic estimated breeding values (GEBV) for grain yield (GY), CKT, Fe, and Zn in an Afr...

Oilseed rape (Brassica napus L.) is sensitive to heat stress during the reproductive stage, but it is not clear whether the male and female reproductive organs differ in their sensitivity to heat stress. In this study, full diallel crossing experiments were conducted among four genotypes of B. napus under control, moderate and high heat stress cond...

Attribution License (CC BY 4.0). Oilseed Brassica species are vulnerable to heat and drought stress, especially in the early reproductive stage. We evaluated plant imaging of whole plant and flower tissue, leaf stomatal conductance, leaf and bud temperature, photochemical reflectance index, quantum yield of photosynthesis, and leaf gas exchange for...

End-of-season drought or “terminal drought,” which occurs after flowering, is considered the most significant abiotic stress affecting crop yields. Wheat crop production in Mediterranean-type environments is often exposed to terminal drought due to decreasing rainfall and rapid increases in temperature and evapotranspiration during spring when whea...

Post-anthesis water use is important for grain yield in wheat under drought because this water is immediately used for grain filling. The aim of this study was to determine whether root capacity for water uptake from deeper layers in the soil profile differed between two genotypes with contrasting stomatal behaviour under terminal drought. The whea...

Terminal drought is a common abiotic stress affecting wheat yield in Mediterranean-type environments. As terminal drought develops, top layers of the soil profile dry, exposing the upper part of the root system to soil water deficit while deeper roots can still access soil water. Since open stomata rapidly exhausts available soil water, reducing st...

Wheat grown in the Mediterranean-type environments of southern Australia is often exposed to end-of-season drought (terminal drought). During the development of terminal drought, soil dries from the top of the profile exposing the upper part of the root system to water stress while deeper roots may still be able to access deeper soil water for grai...

The possibility of stale seedbed technique as a weed management strategy in direct seeded upland rice was examined in a field experiment conducted at Mannuthy, Kerala, India. Major growth characteristics and yield of rice were noted. Rice yield was significantly influenced by the stale seedbed treatments. The highest yield (2567kg/ha) was obtained...

A field experiment was conducted in Kerala, India, in 1999 to test the feasibility of stale seedbed technique for the management of Sacciolepsis interrupta, a problem grass weed in semi-dry rice cv. Jyothi. Adoption of stale seedbed technique reduced the competition from all the weeds including S. interrupta. Stale seedbed with paraquat showed redu...
