“…The challenge to wheat production is further compounded by losses incurred due to wide-spread occurrence of diseases. Spot blotch disease of wheat, caused by Bipolaris sorokiniana , has emerged as a critical challenge to wheat cultivation, especially in the warm and humid areas of the world (Dubin and Rajaram, 1996 ; Nizam et al, 2012 ; Arseniuk, 2014 ). B. sorokiniana is a hemibiotrophic fungal pathogen (Dubin et al, 1998 ) that displays a wide variability in natural habitats (Mehta, 1981 ; Duveiller and Garcia Altamirano, 2000 ; Chand et al, 2003 ; Pandey et al, 2008 ; Asad et al, 2009 ).…”

Spot blotch, caused by the hemibiotropic fungus Bipolaris sorokiniana, is amongst the most damaging diseases of wheat. Still, natural variation in expression of biochemical traits that determine field resistance to spot blotch in wheat remain unaddressed. To understand how genotypic variations relate to metabolite profiles of the components of defense-signaling and the plant performance, as well as to discover novel sources of resistance against spot blotch, we have conducted field studies using 968 wheat genotypes at 5 geographical locations in South-Asia in 2 years. 46 genotypes were identified as resistant. Further, in independent confirmatory trials in subsequent 3 years, over 5 geographical locations, we re-characterized 55 genotypes for their resistance (above 46 along with Yangmai#6, a well characterized resistant genotype, and eight susceptible genotypes). We next determined time-dependent spot blotch-induced metabolite profiles of components of defense-signaling as well as levels of enzymatic components of defense pathway (such as salicylic acid (SA), phenolic acids, and redox components), and derived co-variation patterns with respect to resistance in these 55 genotypes. Spot blotch-induced SA accumulation was negatively correlated to disease progression. Amongst phenolic acids, syringic acid was most strongly inversely correlated to disease progression, indicating a defensive function, which was independently confirmed. Thus, exploring natural variation proved extremely useful in determining traits influencing phenotypic plasticity and adaptation to complex environments. Further, by overcoming environmental heterogeneity, our study identifies germplasm and biochemical traits that are deployable for spot blotch resistance in wheat along South-Asia.

“…One of the most successful interspecific hybrids synthetically developed is Triticale, a hybrid of wheat (Triticum) and rye (Secale). It combines high yielding property of wheat with the ability to grow in harsher conditions due to abiotic stress tolerance inherited from rye (Arseniuk 2015). Similarly, several agronomically important traits have been transferred from wild relatives into cultivars by wide hybridization such as the soft grain endosperm structure from Aegilops speltoides into bread wheat (Pshenichnikova et al 2010), black rot resistance from Brassica carinata into cauliflower (Sharma et al 2017), and leaf rust resistance from Aegilops tauschii to triticale (Majka et al 2018).…”

Climate change calls for new methods and plant materials to breed crops adapted to new environmental conditions. Sustainable forage and amenity grass production during periods of severe drought and heat waves during summer, and unequal distribution of precipitation over the year will require drought-tolerant genotypes. However, high-yielding ryegrasses (Lolium spp.), which are the most commonly used grass species, suffer during abiotic stresses. Introgression of drought and heat tolerance from closely related fescues (Festuca spp.) offers an opportunity to develop superior hybrid cultivars to mitigate the negative impact of climate change. Intergeneric cross-hybridization and the development of Festulolium (Festuca × Lolium) hybrids was initiated 100 years ago and resulted in registration of almost one hundred cultivars. For a long time, their genome composition was not known and was debated by breeders and geneticists. In the last three decades, molecular cytogenetic and genomic approaches have enabled their detailed characterization. These studies revealed a gradual replacement of Festuca chromosomes by those of Lolium in consecutive generations leading to an almost complete elimination of Festuca chromatin in the introgression forms. On the other hand, amphiploid cultivars seem to be more stable with the optimal proportions of the Lolium to Festuca genomes at about 2:1. In this mini review, we discuss recent advances in the analysis of the genome composition of Festulolium hybrids with a specific focus on genome (in)stability.

“…Triticale is a new cereal which has been produced by crossing wheat and rye grass. Over years thanks to research and breeding, it has become an important small grain addition to the agricultural repertoire designed to cope with the needs of many regions of the world for feed, forage, and sustainable cropping systems (Arseniuk, 2015).…”

Salinity becomes one of the most important and serious agricultural problems. Furthermore, it is an ever-present impendence to crop productivity, especially in the countries where irrigation is a determining factor for agricultural activity. It is known that crop matching is one of the ways to overcome the problem of soil salinity, such as triticale plant which was recognized as a crop suitable for growth in saline soils. Two field trials were conducted to study the interaction effect of soil salinity levels, Humic substances and mineral phosphorus fertilization, it can further illustrate how triticale cultivation in saline soils is developed by studying the impact on plant height, forage fresh and dry weight, total NPK uptake in dry forage. All privies parameters were depressed with increased salinity levels. While the order of Humic substances for their influences on triticale growth parameters and total N, P and K uptake were as follows: Falvic soil, Falvic foliar, Humic soil, Humic foliar, without Humic substances. While, applying 140 kg P ha-1 gave the highest results of previous parameters. While the interaction effect shows that when using 70 kg p ha-1 in low soil salinity (SL), or when using 140 kg p ha-1 in moderate soil salinity (SM), the effect of Humic substances will become clear on fresh and dry forage yield and total N, P and K uptake of triticale. Therefore, it is preferred that applying Humic substances and mineral phosphorus fertilization to the improvement of triticale production with increasing soil salinity.
