“…This revealed that there was significant genetic variability for yield and yield-related parameters among the genotypes under study and it offers a strong chance of improving traits of interest in wheat breeding program. Kumar et al [18], Berhanu et al [19], Ahmed et al [20], Bhanu [21], Wani et al [22], Kaur et al, [8], Bayisa et al [23] and Sood et al [24], also came to similar conclusions and found that wheat genotypes differed in yield and yield-related characteristics.…”

Wheat (Triticum aestivum L.) is described as the ‘King of Cereals’ is a leading cereal crop which plays a crucial role in feeding the hungry world and improving global food security. Understanding the contribution of yield components to the variation of grain yield is essential for designing breeding programs and increasing grain production. A diversity panel of 200 genotypes including 145 accessions and 55 landraces of wheat were evaluated in Augmented Design for genetic variability and correlation between grain yield and yield related components. Analysis of variance revealed significant differences among the genotypes for all the traits except chlorophyll fluorescence. The highest phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were recorded for effective number of tillers metre-1 followed by biological yield row-1, flag leaf length, grain yield row-1. Heritability coupled with genetic advance percent of mean was high for effective number of tillers metre-1, followed by biological yield row-1, flag leaf length, grain yield row-1. Association studies revealed a highly significant and positive association of grain yield row-1 with biological yield row-1 (0.805), 1000-grain weight (0.476), effective number of tillers metre-1 (0.328), flag leaf width (0.137) and harvest index (0.133) whereas, it showed a significant negative association with days to maturity (-0.304) and days to 50% heading, (-0.291). The study revealed that days to maturity, days to heading, 1000-grain weight and effective number of tillers metre-1 could be considered the most appropriate traits for improvement and selection of trait to achieve stable and high yielding early wheat genotypes.

“…Kumar et al (2019) revealed PH had an upper significant positive correlation with EL while negatively correlated with BYP. EL showing a negative correlation with BYP also resulted in many researchers' reports (Burio et al, 2004;Bhushan et al, 2013;Avinashe et al, 2017;Ahmed et al, 2018). BYP has a significant negative correlation with HI.…”

Wheat breeders focus on enhancing the production potential of bread wheat by creating new varieties with acceptable genetic makeup to combat the pressure of rising human population consumption. Research to resolve this issue transpired during the Rabi of November 2021– April 2022 at the Lovely Professional University, Punjab, India. Developing the field trial used an augmented block design, 45 F4 segregating population genotypes, and five checks. Data on characteristics, such as days to 50% flowering, days to maturity, number of productive tillers, plant height, ear length, and weight, number of spikelets ear-1 and grains ear-1, 1000 grain weight, grain yield plant-1, biological yield, harvest index, and chlorophyll index underwent assessment. Highly significant variations between the genotypes for all the traits had the analysis of variance determining these, except 1000 grain weight and chlorophyll index in the treatment test and the test versus check. In this study, the harvest index, biological yield plant-1, and grain yield plant-1 are all higher for the phenotypic and genotypic coefficient of variances (PCV, GCV). The genetic advancement and heritability are highest for days to maturity, ear weight, number of grains ear-1, biological yield plant-1, grain yield plant-1, and harvest index. Studies on the relationships between various traits divulged that the number of productive tillers and harvest index had a positive, strong link and a direct effect with grain yield plant-1. These findings support the application of genetic modification to increase seed yield in bread wheat.

“…The values of mean square (MS) for all morpho-agronomic traits showed highly significant differences between sowing seasons of 45 einkorn lines (Table 1). This finding indicates the existence of a high degree of variability in the lines to be exploited in breeding program [28,29]. All of the einkorn lines in the trials flowered well when sown both in autumn and in spring.…”

Nowadays diploid einkorn wheat (Triticum monococcum L. ssp. monococcum), widely cultivated in the Neolithic age, has been reconsidered as the valuable genetic resource for breeding and organic farming due to its high resistance to pests and diseases, adaptation to harsh climates, ability to provide acceptable yields on poor soils even with low/without inputs and high nutritional values. In this research, local 45 cultivated einkorn lines, selected from 500 single rows planted by each single spikes collected from total 50 farmers’ fields in 34 villages of Kastamonu/Turkey, were evaluated in terms of their morpho-agronomical traits and nutritional characteristics during two sowing seasons, autumn 2017 and spring 2018. Einkorn lines sown in two different seasons showed significant variations for heading time, plant height, lodging susceptibility, spike length, number of spikelets per spike, gross grain yield, amount of glume, single kernel weight, kernel diameter, hardness index, grain protein content and the color (a, b, L) values of flour. Furthermore, most of the correlation coefficients between these characteristics were found to be significant. All lines showed “facultative” growth habit, flowering well when sown both in autumn and in spring. Although lines sown in autumn had more yields, the same lines sown in spring provided higher grain quality and more resistance to lodging due to having shorter stems. In order to enable sustainable future use of einkorn, further research is suggested for reduction of plant height to avoid lodging and improvement of grain yield to compete with modern high yielding wheat cultivars.
