“…Stem girth showed high PCV and GCV in kharif (22.91% and 22.89%) but medium PCV and GCV in rabi (10.52% and 10.24%). Moderate PCV for head diameter by Reena et al [15] and moderate GCV for plant height, head diameter and 100 seed weight by Kumar et al [21] and Neelima et al [20]. Further, low PCV for the characters volume weight, days to 50% flowering, days to maturity and oil content was also reported by Kalukhe et al [22] and Makane et al [23].…”

The present investigation was conducted to study genetic parameters for sixteen characters viz., days to 50% flowering, days to maturity, plant height, head diameter, leaf length, leaf width, number of leaves per plant, 100 seed weight, volume weight, seed yield/plant, seed length, seed width, stem girth, leaf area index, chlorophyll content and oil content at ICAR-Indian Institute of Oilseeds Research during kharif-2022 and rabi-2022-23, respectively. The study included a total of 50 advanced (BC2F6) interspecific derivatives derived using five diploid annual compatible Helianthus species along with three checks (ARM-243B, DRSF-108 and DRSF-113). Analysis of variance revealed significant differences for all the traits. High variation was observed for plant height and seed yield/plant and lowest was observed for 100 seed weight, oil content and head diameter. The difference between GCV and PCV was low for all the characters indicating less influence of environmental factors on the expression of these traits. High heritability coupled with high genetic advance in percent of mean was observed for plant height, leaf width, number of leaves/plant, volume weight, 100 seed weight, stem girth, leaf area index and chlorophyll content indicating additive gene action in the expression of these traits. Simple phenotypic selection may be effective for improving these characters. High heritability coupled with low genetic advance was observed for days to maturity and oil content suggesting involvement of non-additive gene action in the expression of these traits indicating little scope for further improvement through individual plant selection. The results showed that the experimental material used had a substantial quantity of genetic variability to be used in crop development programs in the future.

“…The genotypes by environment interaction was significant (P<0.05) for days to 50% flowering and significant (P<0.01) for the other traits, indicating the differential responses of genotypes to the two environments. Javed and Aslam (1995), Jan et al (2005), Kumar et al (2014) and Khan et al (2017) found significant mean squares for genotypes environment (drought, locations or salinity) their interaction for SY/P, HD, oil %, days to maturity and 100-seed weight. 53.25, and 53.67 for F 1 -hybrids, females and males; respectively with an overall mean of 52.92 (Table 4).…”

“…Rauf and Sadaqat (2007) and Salem et al (2013) indicated that sunflower genotypes differed in their tolerance to drought. The interaction of genotypes x environment was significant for SY/P (Kumar et al 2014 andKhan et al 2017). The close estimates of PCV and GCV at loamy sand and clay soils resulted in unreliable estimates of broad sense heritability of 98.85 and 96.67%; respectively.…”

Twenty-six genotypes of sunflower (16 F 1 -hybrids, four female lines, four restorer lines and two check varieties; Sakha 53 and Giza 102) were evaluated under two contrasting environments, i.e., loamy sand soil at A.R.C., Arab El-Awamer Res. Stn., and clay soil at Assiut Univ. Exper. Farm in season 2016. Genotypes mean squares of 13 studied traits was significant (P<0.01) either in the separate or in the combined analysis. The differences between the two environments were significant for all traits except head diameter (HD). The genotype x environment interaction was significant for all traits, indicating differential responses of genotypes to the two environments. The F 1 -hybrids, females and males were earlier than the two checks in days to 50% flowering. The fertile clay soil delayed days to 50% flowering than loamy sand soil. The phenotypic (PCV%) and genotypic (GCV%) coefficients of variability were low, and heritability in broad sense was intermediate (43.17%) for days to 50% flowering. The combined analysis of plant height showed high PCV (13.58%), GCV (11.81%) and heritability (75.58%). The GCV of head diameter was high and reached 15.95, 14.41 and 11.84% at loamy sand, clay soil and combined analysis; respectively. Stalk diameter was larger at clay than at loamy sand soil, and heritability estimates were 74.19, 77.05 and 66.67% at loamy sand, clay soil and combined analysis; respectively. Four of the F 1 -hybrids was heavier in 100-seed weight than the checks. The GCV and heritability estimates were high for 100-seed weight. Husk % and husk; g of 100 seeds tended to be higher Ezzat E. Mahdy et al., 2018 -30 -at loamy sand than at clay soil. The combined means of oil % showed that five hybrids significantly exceeded the better check Giza 102. Oil % was higher at loamy sand than at clay soil. Heritability estimates of oil % were high at both locations (97.86 and 86.25%) and very low (5.69%) from the combined analysis, because of the large mean squares of GxE interaction. Kernel weight in 100 seeds was higher at loamy sand than at clay soil. The GCV and heritability estimates were high for kernel weight. Number of seeds/head was higher at clay soil than at loamy sand. Three F 1 -hybrids significantly exceeded Sakha53in kernel weight from the combined data. The GCV and heritability estimates were high for NS/H. Seed yield/head and oil yield/head were higher at loamy sand than at clay soil, and four F 1 -hybrids were significantly better than the check. High estimates of GCV and heritability were high for NS/H. The GCV estimates in seed yield were 43.48, 39.33 and 33.57%, and heritability were 98.85, 96.67 and 75.22% at loamy sand, clay soil and combined analysis; respectively. The resulted indicated that the genetic materials should be evaluated under diverse environments to get reliable estimates of genetic parameters.

Evaluation of Morpho-Physiological Traits in Rice Genotypes for Adaptation under Irrigated and Water-Limited Environments

Drought is one of the major limitations to rice productivity worldwide. The present study compared variation in seventeen rice genotypes of Egyptian origin for morpho-physiological traits to identify the best genotypes with combination of adaptive traits under water-limited condition (DS). The DS reduced days to heading (DTH), plant height (PH), flag leaf angle (FLA), flag leaf area (FLAR), chlorophyll content (CHC), relative water content (RWC), grain yield (GY), and its components. Among genotypes, Hybrid 2 expressed the highest GY, panicle length (PL), number of tillers (NT), panicles per plant (NPP), and harvest index (HI) with maximum spikelet sterility (SS) under non-stress condition (NS), while the same genotype expressed ≈ 41% yield reduction under DS. The genotype Giza 179 had earlier DTH, higher and stable GY, FLAR, and yield component traits such as NPP, PW, and HI across the water regimes with least yield reduction (30.5%) under DS. The GY and FLAR, RWC, PL, NT, NPP, PW, and HI were positively correlated under DS. The cluster analysis showed a similarity index of 25% among genotypes. The high yielding genotypes Giza 179, IET 1444, and IRAT 170 had also increased yield components (PL, NT, NPP, PW, TGW and HI) under DS that were attributed to highest FLAR, RWC, and PH, while having reduced LR, FLA, TR, and SS; therefore, these genotypes were categorized as drought-tolerant. The Hybrid 2 and Giza 179 genotypes can perform well under NS; however, the cultivation of Giza 179, Sakha 107, IET 1444, and IRAT 170 would give an advantage in DS-prone areas, hence, these can be used as a donor parental line in future rice breeding programs.
