“…For all traits genotypic correlation values are higher than phenotypic correlation values which indicates little influence of environment. Number of grains per spike, spike length, peduncle length, 1000 grains weight and biological yield per plot showed positive and significant correlation with grain yield per plot which is similar to the findings of Adhikari et al (2018) [3] , Rashidi et al (2012), Vaghela et al (2021) [23] , Tambe et al (2013) [21] , Elahi et al (2020) [10] , Dabi et al…”

Genetic variability, correlation and path analysis was studied for yield and its attributing traits in forty diverse durum wheat genotypes under restricted irrigation conditions in north Gujarat conditions and studied 11 morphological, 3 physiological and 2 biochemical traits which contributes for yield in durum wheat. The analysis of variance revealed that the significance difference among the genotypes for all the studied traits except canopy temperature after 5 days and 15 days of anthesis. Traits viz., grain yield per plot, number of grains per spike, spike length, peduncle length, 1000 grains weight, harvest index and chlorophyll content showed moderate GCV and PCV values. High heritability with high genetic advance recorded in five traits. Under restricted irrigation conditions number of grains per spike, spike length, peduncle length, 1000 grains weight, biological yield per plot was positive correlated with grain yield per plot. Harvest index showed highest direct effect towards the grain yield per plot followed by biological yield per plot and number of grains per spike. For selection of yield contributing traits number of grains per spike, spike length, 1000 grains weight, harvest index and biological yield per plot are important for future breeding strategies.

“…The selection of desirable genotypes can be achieved through the proper characterization of available genotypes. Different authors, including Hayadar et al [7]; Vaghela et al [8] and Lamara et al [9] have demonstrated the existence of variability, heritability, and genetic advancement in different yield-related parameters of bread wheat (2022). However, not much variability studies have been conducted for recent genotypes in the study area.…”

Introduction: The experiment was conducted in Research Farm, Rani Lakshmi Bai Central Agricultural University, Jhansi, during Rabi season 2019-2020 using augmented block design in five blocks. The objective was to assess the genetic variability and character association analysis of eighty-two wheat genotypes. Methodology: Eighty-two genotypes including three checks (HI1544, DBW110, and GW322) observed its various quantitative traits for genetic variation, heritability, genetic advance, and character association. The observations were recorded on fifteen agro-morphological and physiological characters viz; days to 50 percent heading, days to maturity, canopy temperature (oC), chlorophyll content, flag leaf width (cm), flag leaf length (cm), tillers per meter, peduncle length (cm), plant height (cm), spike length (cm), awn length (cm), 1000-grain weight (g), grain yield per plant (g), biological yield per plant (g) and harvest index (%). Statistical analysis was carried out by R Programming and SAS version 9.2 statistical software. Results: The genotypes IC443619, IC6165734, and IC624496 were having earlier days to maturity than the best check DBW110. HD3086, K0307, PBW343, RAJ3, 765, and MACS6478 have been found promising for grain yield per plant. The highest Phenotypic coefficient of variation (PCV) and Genotypic coefficient of variation (GCV) were recorded for tillers per plant followed by awn length, peduncle length, flag leaf length, flag leaf width, plant height, and spike length. Heritability in broad sense wide ranged from 26.3 percent for canopy temperature to 95.63 percent for grain yield per plant. The grain yield per plant showed a positive and significant correlation with biological yield per plant, harvest index, and tillers per meter, whereas it showed a negative significant association with awn length. Conclusion: The relationship between grain yield per plant and biological yield per plant, harvest index, and tillers per metre was positive and significant, indicating that an increase in these component characteristics will also boost economic grain yield per plant.

“…Though, the correlation studies helps in determining the composition of a complex traits i.e. grain yield, it does not provide an precise magnitude of direct and indirect effect in the direction of the yield (Vaghela et al, 2021). As a reason, now-a -days breeders also wants to know their cause and effect relationship through path analysis procedure.…”

The present investigation was conducted at the Breeder Seed Production Unit, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, M.P., India during November to April, (Rabi season), 2021 to 2022 analyse grain yield and its attributing traits of wheat by correlation and path coefficient analysis. The twenty genotypes were in randomized complete block design with three replications. The results indicated that the biological yield per plant had highly significant correlation followed by harvest index with a moderate positive value and is significant with the grain yield per plant. Similarly the analysis of direct and indirect effects shows that the plant height, flag leaf length, flag leaf width, days to 50% flowering, grains per spike, biological yield per plant, and harvest index had positive direct effect on grain yield per plant. Hence it may be considered that traits namely, plant height, flag leaf length, flag leaf width, days to 50% flowering, grains per spike, biological yield per plant, and harvest index may be utilized for yield improvement breeding strategies in wheat. However, biological yield and harvest index will be given prime importance during selection of traits, due to their significant association and having a direct or indirect effect in crop yield improvement.
