In the present study, seventy-four potato genotypes were evaluated for diversity analysis during autumn 2017-2018 and 2018-2019 at NARC, Islamabad. Our results showed significant diversity in qualitative traits with reference to skin color of five types (Red, yellowish, brown, light yellow, light brown skin color tubers=5), three types of flesh color (Yellow, cream and white flesh color tubers=3), three sizes of tubers (Medium, small and large size tubers=3) and four shape of tuber (Oval, round, oblong, elliptic= 4 shapes) and four different eyes color (Brown, light brown, dark red and yellow eyes color=4). Potato genotype under study had very high genetic variance for quantitative attributes including weight of tuber per plant and weight number of tubers per lane, leaf area and plant height. Significant positive correlation was observed between number of tubers per plant (TPP) with number of eyes on tubers (r = 0.241) and number of tubers per lane (TPL) (r = 0.349). Plant height was found significantly positive correlated with leaf area (r= 0.456), germination percentage (r = 0.255) and weight of tubers per plant (r = 0.307). Leaf area (LA) showed positive significant correlation with number of tubers per plant (r = 0.466) and weight of tubers per plant (r = 0.263), yield and harvest index (r = 0.798, 0.755, 0.255). Weight of tubers per lane (WTL) showed positive correlation with weight of tubers per plant (r = 0.387). Regarding the interrelation between the traits and genotypes, the first two principal component axes (PC1, 24.83% and PC2, 23.46%) accounted for about 48.29% of the total variability reflecting the complexity of the variation between the plotted traits of genotypes. The present study will be useful for the precise selection for effective breeding program.","PeriodicalId":14298,"journal":{"name":"INTERNATIONAL JOURNAL OF PLANT AND ENVIRONMENT","volume":"94 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79043637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In current study forty-two Brassica germplasm (B. napus = 17, B. juncea = 25) were evaluated against Alternaria leaf spot disease at research area of Plant Pathology Research Institute (PPRI), Ayub Agricultural Research Institute (AARI), Faisalabad, Pakistan. These germplasms were sown in augmented design with 10 cm plant x plant and 60 cm row x row distance in single replication. A susceptible check KJ-159 was sown after every two entries. Data were recorded on 0-9 disease severity rating scale. Out of 17 germplasm of B. napus no germplasm was found to be immune. Two germplasm exhibited highly resistant while eight germplasm showed resistance response against the disease. Six germplasm were moderately resistant and only one showed moderately susceptible response. Similarly, out of 25 germplasm of B. junceas even were found moderately resistant and ten showed moderately susceptible response. Seven were susceptible while only one germplasm was highly susceptible. Then in-vitro efficacy of different fungicides was evaluated against A. brassicae. For evaluation of fungicides Potato Dextrose Agar (PDA) amended with five different fungicides at different concentrations (10, 50, 100 and 200 ppm) was used. Experiment was conducted in completely randomized design with ten replications. Data were recorded on mycelial growth (mm) of fungus. Mancozeb (Ethylene bisdithiocarbamate) and Nativo (Tebuconazole) significantly inhibited the growth at all concentrations while Antracol (Propineb) was significantly least effective against A. brassicae.

Purposely, the barley was procured from the local market of Multan, Pakistan by considering quality traits account i.e., colour, length, width, and thousand kernel weight. The cleaned barley was subjected to malting till seed germination for up to 4 days. After the process of germination, the seed was fried in the drier at 65 ℃ for 16 hours followed by flour development. The colour value of un-malted barley for l, a, and b were 54.23, 1.91, and 11.21 whilst malted barley presented 53.52, 0.86, and 11.03, respectively for the same traits. Afterwards, the pretzels were prepared by following the standard recipe by planning various treatments i.e., T0 (100% wheat flour), T1 (80% wheat flour, 20% malted flour), T2 (60% wheat flour, 40% malted flour), T3 (40% wheat flour, 60% malted flour), T4 (80% wheat flour, 20% un-malted flour), T5 (60% wheat flour, 40% un-malted flour) and T6 (40% wheat flour, 60% un-malted flour).

From the rainy season of 2016 to the summer season of 2019, the mean values offrequency, abundance, and density against the N gradient were calculated. Therefore the results showed that, nitrogen is essential forthe competitive equilibrium of C3 and C4 species. This study suggests that N deposition-induced changes in competitive interactionsmay be disadvantages to native species that thrive in low-nutrient environments, such as N2-fixers, ultimately leading to changes in thecomposition of plant communities. In comparison to N2 fixers, non-N2 fixers appear to be more effective at using extra N for growth.Our findings show that the diversity of grasslands has dramatically shifted from native to introduced species, proving that non-nativespace invaders are destroying the rich grassland ecosystems around the world. By changing the dominant species and its response towhich species dominates the response at the community level, this change in abundance may alter the ecosystem functions.
