“…The durable resistance of these varieties may be used for future breeding program against leaf rust in wheat genotypes. Similar results of wheat screening were reported by Arora et al [26], Abdul et al [27], Arain et al [20], Cheruiyot et al [23] and Fayyaz et al [28].…”

“…The genetic level of resistance in these cultivars is sustainable and resistance breaking is low. Similar results were obtained by Arain et al [20] where wheat genotypes/varieties were screened for leaf rust at six different experimental locations. In another study, 56 commercial wheat varieties were screened against spot blotch under controlled and field conditions [21].…”

The experiment was carried out to screen and evaluate commercial wheat varieties against leaf rust and grain yield at Agricultural Research Station, Baffa, Mansehra, Pakistan. The experimental location is considered favourable for development of leaf rust disease. Twenty wheat varieties including susceptible control Morocco showed variable response to leaf rust and no variety was found completely resistant to leaf rust. Three varieties (NARC-2011, Pirsabak-08 and Siran-2010) were moderately resistant (MR), 11 varieties (NARC-09, Punjab-11, Pirsabak-04, Pirsabak-05, Fisalabad-08, Pakistan-13, Pirsabak-15, Pukhtunkhwa-15, Shakaar-13, Pirsabak-13 and NIFA-Insaaf) were moderately susceptible (MS), 3 varieties (Millat-11, Lasani-08 and Atta Habib) showed medium response (M) while 3 varieties (Sehar-2006, Glaxy-2013 and Morocco) were susceptible (S) to leaf rust. The result of statistical analysis for yield attributing characters showed significant variations for number of grains per spike, 1000 grain weight (g), grain yield (tons/ha), biological yield (tons/ha) and Harvest Index (%). Number of grains per spike ranged from 41 to 67 showed by varieties Morocco and NARC-2011, 1000 grain weight from 32 to 61 grams by varieties Glaxy-2013 and Siran-2010, grain yield from 1.92 to 5.10 tons/hectares by varieties Sehar-2006 and NARC-2011, biological yield from 8.36 to 10.87 tons/hectares by varieties Morocco and Pakistan-13, and harvest index from 22.29 % to 49.22 % by varieties Morocco and NARC-2011. Screening results of wheat varieties revealed that the level of resistant to leaf rust is at risk due to possible evolution of rust pathogen in experimental location and the potential of grain yield of these varieties may be effected by leaf rust.

“…The phenotypic assessment of yield traits: Observations were documented on grain yield and five yield-related traits under S and NS conditions. At maturity, five randomly selected plants per replicate were harvested from the two central rows to collect the data on yield and other agronomic traits, viz., days to heading (DH), plant height (PH), and spike length (SL) following Arain et al (2017). Data on spikelets per spike (SPS), grains per spike (GPS), and main spike yield (g) were recorded after harvest from the main tillers of the five randomly selected plants.…”

The salinity tolerance indices, principal component analysis, and cluster analysis were employed to evaluate the 16 wheat genotypes for agro-morphological traits under normal and saline (834-1850ppm/pH 7.3-7.5 soils) conditions for two consecutive years 2015 and 2016 at the Nuclear Institute of Agriculture (NIA), Tando Jam, Sindh, Pakistan. Combined analysis of variance revealed significant variations among the studied genotypes. Moreover, a significant interaction of genotype by year was observed only between grain yield and grains per spike indicated importance of the trait for improvement of grain yield in wheat. Correlation of Ys (yield under stress) and Yp (yield under nonstress) with tolerance index (TOL), stress stability index (SSI), yield stability index (YSI) and yield index (YI) indicated that mean productivity (MP), geometric mean productivity (GMP), harmonic mean (HM) and STI (stress tolerance index) were found as better indicators of Ys and Yp. The principal component analysis revealed two components that justified 73.23% of the total variation. Bi-plot and cluster analyses classified the genotypes i.e., V3-10-9, V3-10-31, and V3-10-32 based on MP, GMP, STI, and HM indices as stable and high yielding, while C3-98-8 and V2-10-15 based on YSI and YI. These genotypes could be exploited directly in the varietal release program and or as a source of potential donors to stack genes for salinity tolerance.

Аbstract. The response of 1262 durum wheat lines to the cause agent of leaf rust Puccinia triticina was studied. The investigation was carried under infection field conditions during 2013-2015 at Dobrudzha Agricultural Institute (DAI) – General Toshevo, Bulgaria. Over the years of investigation, a maximum high infection background was developed by the cause agent of the disease, including all pathogen pathotypes identified during this period. The race variability in the population of the pathogen during the period was determined at the Plant Pathology Laboratory of DAI according to a validated methodology for working with rusts. Seventy-one phenotypically different virulent pathotypes were established. Fifteen new races of P. triticina were also identified, which have not been present during the previous 15 years in Bulgaria. Seventeen lines and one cultivar with a certain degree of resistance to the pathogen were selected. The selected lines can be involved in the breeding programs for developing initial material with resistance to leaf rust P. triticina.
