Rht Genes

Using STSs and SSR markers, three worldwide the most important major height reducing genes, Rht-B1b, Rht-D1b and Rht8 were evaluated in this paper. In the analysed set of hexaploid wheat, composed of 172 genotypes originated from more than 20 countries, Rht-B1b, Rht- D1b and Rht8 were found in 40%, 22% and 62% of cases, respectively. In genotype groups of domestic and foreign origin, the highest difference in allele frequency was determined in the case of Rht8, which was more frequent in domestic genotypes (78, 3%). The Rht-B1b was dominantly present in foreign germplasm (57, 6%). Portion of Rht-D1b was almost equal with 22, 6% in domestic and 21, 2% in foreign varieties. Obtained results and accepted methodology for detection of these three, the most important Rht genes, represent great start point for Marker Assisted Selection (MAS) for high yielding wheat genotypes in agro climatic conditions of Serbia and Mediterranean area. .

Wheat is a sub-tropical cereal that can be planted in the tropics, on the highland with altitude >1000 m asl. The development of wheat in the highlands compete with horticultural crops, so the creation of tropical wheat that is adaptive to lowland and drought tolerance is an alternative problem-solving. The aims of this study is to test the generation and to screen three type of  mutant that is adaptive in lowland with high temperature. The study was conducted at Tamalanrea Jaya, Tamalanrea regency, Makassar province from May to August 2017. The research was conducted on hydroponic media in the plastic house (green house) at altitude <800 m asl with an average temperature of 28oC (morning) and an average temperature of 33oC (afternoon). The study was used split-plot design with the main plot of polyethylene glycol (PEG), ie 0%, 5%, 10%, and 15%; the plot was 15 wheat genotypes. The results showed that the addition of PEG concentrations at 5%, 10% and 15% decreased the crop yield by 35.91%, 55.63%, and 71.83%. Adaptive and potential genotypes developed in lowland with dry climatic conditions are genotype N.200 2.4.B.6 and genotype N.300 4.3.6

Wheat Genotypes

Understanding how changing environment and cultivars influence crop phenology and potential yield is essential for crop adaptation to future climate change. Plant Genetic Diversity (PGD) provides the basis for survival in plants in nature and for crop improvement. Under changing climate scenario and increase in population pressure, wheat genotypes with attributes such as; short duration, lesser water loving, and abundant yield potential are of considerable importance. The present study was designed to evaluate best wheat genotypes which may better perform under the changing climatic conditions of southern Punjab, Pakistan. A field trial to study the comparative performance of newly evolved four genotypes; Millat-2011, Faisalabad-2008, Punjab-2011 and AARI-2011 was conducted at two different agro-climatic conditions of Dera Ghazi Khan, Punjab, during crop season, 2013-2014. The design used was randomized complete block with three replicates. Plot size was maintained as (4x 6m) and (2.5x 6m) respectively, for site-1 2. Seed rate of 125 kg ha-1 was used. The recommended dose of NPK (128-114-62 Kg/ha), irrigation, weed control methodology and all other agronomic practice were kept the same for all the treatments in both sites. Statistical analysis of the data was carried out by studying different yield components (Germination count m-2, Number of Fertile tillers m-2, No. of spikelets spike-1, Plant height at maturity, Spike Length, No. of grains spike-1, 1000 grain weight and Grains yield) and their means were separated by using the least significance difference test. As per results achieved from the experiment, performance (growth and yield attributes) of genotype Millat-2011 was best as compared to all other genotypes tested under local condition. Millat-2011 recorded a significant increase in all growth and yield variables, including germination, grains number, test weight and yield of wheat under local conditions as compared to rest three genotypes.
