Terminal heat stress
-
High temperature is a major environmental stress factor limiting wheat (Triticum aestivum L.) productivity. Improvement of heat tolerance in wheat is an important breeding objective. The present investigation was carried out to evaluate and identify terminal heat tolerant bread wheat genotypes on the basis heat susceptibility index.

A field experiment was conducted in Rabi 2015 in a randomized block design with the objective to screen advanced breeding lines (genotypes) of Indian mustard (Brassica juncea L. Czern and Coss) for different physiological parameters viz, chlorophyll content, membrane stability index (MSI %), relative water content (RWC %) and electrolyte leakage and yield related to terminal heat tolerance. The study indicated that genotypes, ‘Pusa Bold’, ‘NRCHB-101’ and ‘PRO-5222’ had tolerance to high temperature at terminal stage.

The investigation was conducted on three mungbean [Vigna radiata (L.) Wilczek] genotypes namely MH-421, MH-318 and Basanti genotypes to study their biochemical, and yield response in relation to terminal heat stress tolerance. The plants were raised in earthen pots (30 cm diameter) filled with 5.5 kg of dune sand (Typic Torrispamments) under screen house conditions. High temperature stress was given by manipulation of sowing dates i.e. normal sown (12th March, 2013) and late sown (29th March, 2013).

Wheat (Triticum aestivum) is the second most important food crop in India only after rice and providing food for about 2 billion people which is about 36% of the world population. Annual production of wheat and rice together should be increase by 2 mt every year in order to maintain self-sufficiency for wheat in India. The demand of wheat is projected to be 109 mt by 2020 in India. Globally, the demand for wheat by the year 2020 is forecasted to be around 950 mt.

A study was conducted at Wheat Breeding section, RPCAU, Pusa, Samastipur, Bihar during rabi 2016-17 to evaluate the genotypes of bread wheat (Triticum aestivum L.) for terminal heat tolerance. Observations were recorded on plant height, number of tillers per plant, flag leaf area, days to fifty per cent flowering, canopy temperature, relative water content, spike length, number of grains per spike, spike fertility, chlorophyll content, days to maturity, thousand grain weight, harvest index, yield per plant, thousand grain weight susceptibility index and heat susceptibility index.

The present study was conducted to determine genotypic variations for normalized difference vegetation index (NDVI) and canopy temperature (CT) in wheat under terminal heat and combined heat and drought stresses. Forty-four wheat genotypes were evaluated under late sown with irrigation (heat stress) and without irrigation (combined heat and drought stress) in an environment with average temperatures of 28.6°C during the growing season and 30.62°C during the grain filling stage.

The present study was carried out at Dept. of Genetics and Plant Breeding, BHU during rabi of 2016-17 comprising of 101 barley genotypes. Association of yield and its contributing traits was analyzed and these correlations were partitioned to have clear understanding direct and indirect effects on the grain yield per plant under terminal heat stress.

Wheat (Triticum aestivum L.), a staple food crop is of great commercial importance. Its production is restricted due to various abiotic stresses. There are indications that the wheat production is consistently limited by terminal heat stress. Here, performance of forty genotypes of wheat was undertaken for assessment of direct selection parameters (variability, heritability and genetic advance) and their relation with heat tolerance.

Among the crops that feed human beings, Wheat (Triticum aestivum L.) is the second most important cool season crop in India. A drastic reduction in wheat production was observed due to increasing temperature. It has been estimated that global mean temperature is rising at 0.3% per decade which may cause 50% decline in wheat yields in South Asia by 2050. High temperature above than optimum has drastic effect on chlorophyll content which is also reflected by normalized difference vegetative index (NDVI).

In India, wheat is cultivated on around 29.8 mha that produces 92.5 mt with an average productivity of 3.1 t/ha. But in recent scenario of climate change our wheat cultivars succumb to the grave problem of terminal heat stress leading to substantial reduction in its production and productivity. Sixteen genotypes of wheat were used for assessing the molecular diversity for terminal heat stress tolerance against 14 SSR markers linked to the trait of interest. Results revealed that amplified alleles ranged from185 bp to 230 bp.

Lentil (Lens culinaris Medikus) is an important winter season grain legume crop, mostly grown on residual soil moisture and is frequently subjected to terminal drought and heat stress, that results in low and variable seed yields. Moreover, delay in sowing even for two weeks causes the reproductive and grain filling phase of this crop to coincide with a period of substantially high temperature resulting in yield losses by reduced seed set, seed weight and accelerated senescence.

The hydrogen-charged specimens were heated to four peak temperatures of 250C, 300C, 350C, and 400C, and then cooled to room temperature at cooling rates of 0.3 C/min under three tensile hoop stresses of 80 MPa, 100 MPa, and 120 MPa. The cool-down specimens showed that high peak heatup temperature led to lower hydrogen content and that larger tensile hoop stress generated larger radial hydride fraction and consequently lower plastic elongation.

The small heat shock proteins function as molecular chaperones, an activ-ity often requiring reversible oligomerization and which protects against irreversible protein denaturation. An abundantly produced small heat shock protein termed p26 is thought to contribute to the remarkable stress resistance exhibited by encysted embryos of the crustacean,Artemia francis-cana. Three novel sequence motifs termed G, R and TS were individually deleted from p26 by site-directed mutagenesis.
