Genetic Characterization and Variability Analysis of Chickpea (Cicer arietinum) Elite Germplasm under Different Cropping Conditions

In current study 113 diverse genotypes of chickpea has been evaluated during rabi 2019-20 and 2020-21 under timely sown (TS), late sown (LS) and very late sown (VLS) cropping environment in augmented block design at research farm of ICAR-IIPR, Kanpur for genetic characterization to access the presence of variability among the major grain yield attributing traits under changing cropping conditions. Variation due to block were insignificant and error variance was significant for all three different trials (ie., TS, LS and VLS) conducted during rabi 2019-20 and 2020-21(Table 5) In the present study highest genotypic and phenotypic coefficient of variation was observed for UFP, SYP (g), PB, Y (kg/ha), PY (g), HI (%), BMP (g), HSW (g) and FP (Table 5) While the traits viz., DFI, DFF, DPI, DFP, DMI, DM and PHT (cm), BY (g) and NSP exhibited the moderate to low range of GVC and PCV value under TS, LS and VLS cropping conditions During rabi 2019-20 and 2020-21. Highest value of heritability (%) >60% have been observe for the traits DFI, DFF, DMI, DM, PB, Y (kg/ha), HSW (g), SYP (g), BMP (g) and FP in all three different cropping environments (Table 6 in the current study correlation coefficient analysis have been estimated for the Correlation values (Table 6) for all three different trials viz Timely sown (TS), Late sown (LS) and Very Late sown (VLS) conducted in Rabi 2019-20 and 2020-2021. The Pearson correlation coefficients of pooled data were calculated for Eighteen morphological traits The major yield contributing traits such as DFF, PHT (cm), PB, SYP (g), PY (g), Y (g), HSW (g), BY (g) and HI (%) have significantly correlated with all the traits except UFP and NSP (Table 6) The PY (g) exhibited strong positive correlation with Y (Kg/ha) (0.857** and 0.964**); HSW (g) (0.544* and 0.412*); BY (g) (517* and 0.856**); SYP (g) (0.628**and 0.506*); BMP (g) (0.553* and 0.494*); HI (%) (0.459* and 0.706**). Similarly, another chief yield contributing traits like SPY (g) is also positively correlated BMP (g) (0.536* and 0.682**); HI (%) (0.678** and 0.779**); FP (0.774** and 0.964**) and NSP (0.456* and 0.503*) except UFP (Table 7 maximum percentage of variance for all 113 diverse chickpea genotypes has been recorded for PC1(26.83, 26.63 & 31.46 in 2019-20; 29.87, 35.15 & 30.2 in 2020-21) and PC2 (24.19, 22.81 & 12.66 in 2019-20; 18.96, 15.43 & 17.4 in 2020-21) for all three separate trials i.e., TS, LS and VLS (Table 7).

Evaluation of Physico-chemical Characters of Different Genotypes of Karonda (Carissa carandas L.)

The current study was conducted in 2021–2022 at the Post Graduate Laboratory of the Department of Horticulture, School of Agriculture, ITM University Gwalior (M.P.). The presents study was entitled to Study onCollection and Evaluation of Karonda (Carissa carandas L.) Genotypes in Gwalior and Etawah Region. In the present study, 20 Karonda genotypes collected from two region viz. Gwalior and Etawah. The experiment was laid out in Complete Randomized Block Design (CRD) with three replications. The results highlighted that, the genotype GKr9 produced maximum fruit weight (3.96 g), fruit width(18.47 mm). The genotype GKr10, GKr11, GKr12, EKr19 and EKr20 produced highest number of seed per fruit (3.0) and seed weight (0.50 g). However, the genotype EKr14 had maximum total soluble solids (6.17°Brix). However, the genotype EKr19 produced highest TSS: acid ratio (4.95) and ascorbic acid (40.76 mg/100g). The genotype GKr12 and GKr13 had maximum pH of the juice (6.43) and acidity (2.44%). Whereas, the genotype GKr8 had maximum reducing sugar (16.64%) and total sugar (45.20%). Thus, on the basis of present study it may be concluded that the genotype GKr8, GKr9 GKr10, GKr11, GKr12, GKr13, EKr14, EKr19 and EKr20 superior among all the genotypes.

Evaluate the Effect of Different Packaging Materials on the Shelf Life and Quality of Banana Fruit

The experiment was carried out to determine the impact of shelf life on banana cv. grand naine under various packing materials during storage for the current study in the Department of Horticulture lab at ITMU from October to December 2022. In this experiment, low-density polybags and black newspaper bags were employed as packing materials. paper bag, cardboard gunny bag high-density polybag white paddy straw with banana leaves Banana samples were taken at intervals of four days after each treatment to test a range of biological and physical traits, including pH, physiological weight, and peel colour. As these values were given for the analyses of variance and ANNOVA, the treatment group showed the greatest physiological weight reduction as compared to the control group; however, the Treatment T6 high-density white polybag showed the lowest physiological weight loss and the most appealing colour. is recorded in the treatment T6 high-density white polybag, whereas the peel's least yellow hue is observed throughout treatment to regulate the highest total soluble solid brix value was recorded in Treatment T1 low-density black polybag, and the minimum values recorded for these parameters are found in Treatment T0 control, while the maximum ph value was recorded in Treatment T7 banana leaf and the minimum ph value was noted in Treatment T0 control. According to the observational data, the banana fruit's pH rose as it ripened, further from the present experimental findings. The best packaging material suitable for the enhancement of shelf life and maintenance of visual appearance and quality for bananas is low-density black polythene Treatment T1.
