Abstract Simple lattice design with two replicates was used to evaluate 25 tobacco genotypes. The following eight traits were measured and evaluated: plant height (PH), leaf length (LL), leaf width (LW), leaf number per plant (LN), stem girth (SG), leaf area (LA), dry leaf yield (DLW), and fresh leaf yield (FLW). The genotype by trait biplot for tobacco dataset explained 73% of the total variation of the standardized data. The polygon view of genotype by trait presented for the eight different traits of tobacco genotypes showed six vertex cultivars (G4, G5, G11, G12, G18, and G21). Genotype G21 had the highest values for most of the measured traits. Based on a vector view biplot, strong positive associations among LL, DLW, FLW, and LA were detected while near zero correlations between LL and SG, as well as between LL and PH were observed. Generally, based on ideal genotype and ideal tester biplots, it was demonstrated that the selection for high leaf yield should be performed via leaf length, leaf width, and leaf area traits identified as effective selection criteria for high yielding cultivars.

High Potassium Content

Betelvine (Piper betle L.) is commonly consumed as betel quid or paan with areca nut and/or tobacco; and also utilized in Indian medicine systems and in religious ceremonies. The betel production is highly erratic and so is the income of farmers due to natural climatic factors and spoilage during transport. It is therefore important to improve its productivity per vine and per unit area to meet the demand. Correlation, path coefficient and stability analysis was carried out in fifteen genotypes of betelvine including 3 checks under three protected structures, namely, Bareja (E1), Poly tunnel (E2) and Net tunnel (E3). Among the three structures, Net tunnel was found suitable for the cultivation of betelvine in Chhattisgarh. With respect to quality parameters, Meetha paan (2.65 g/100g) followed by Billori (2.23 g/100g) found to have high protein content. Meetha paan (5.89g/100g) followed by Meetha-cum-bangla (5.36g/100g) was also found to possess high starch content. However, low fiber content was recorded in Meetha pan (1.83g/100g), whereas high potassium content was found in Ramtake meetha (933mg/100g) followed by Bidhan pan (991mg/100g). The genotype, Karapaku possessed high potassium content (2.67mg/g). Hedonic five point scale for organolaptic test showed Meetha paan (2.3/5) followed by Bali paan (2.4/5) were less pungent among genotype studied. Highest shelf life was found in genotype Karapaku and Bhaichigudi (18days). The results indicated that number of leaves per vein were positively correlated with leaf width (0.802 and 0.819) followed by leaf area (0.790 and 0.808), leaf area index (0.782 and 0.800), leaf length (0.745 and 0.759), specific leaf weight (0.681 and 0.709), petiole length (0.658 and 0.705), diameter of internodes (0.484 and 0.559) and R-value (0.112 and 0.110) at both phenotypic and genotypic level, respectively. Path analysis identified leaf width (0.8772) and leaf length (0.4712) had direct effects on leaf yield at phenotypic level. Highest positive direct effect on leaf yield was exerted by leaf area (1.3544) followed by leaf width (0.8986) at genotypic level. These characters can be used as selection criterion in a breeding programme to develop varieties of betelvine with high leaf yield. The stability analysis under three different protected structures viz; E1, E2, E3 indicated that the genotypes, Karapaku, Bhaichigudi and Maghai pan are stable across the environment for leaf yield.

Edible grapevine leaves can be consumed as fresh or pickled. After leaves are usually collected from vineyards, they are sold as fresh or brined. In Turkey, the leaves of Sultani Çekirdeksiz and Narince varieties are extremely evaluated for edible purposes. In this study, it was aimed to determine leaf yield and characteristics of vine saplings in nursery parcel. The leaves of Narince (Narince own-roted grafted on 1103 P) and Sultani Çekirdeksiz (grafted on 1103 P) seedlings were the material of the experiment. Cuttings were planted in a single row (16.666 cuttings/da) with 1 m × 6 cm spacing to the nursery parcel. Edible leaves were collected from saplings in two harvest periods. Leaf yield, leaf width, leaf length, leaf area and leaf weight in fresh vine leaves were determined. Depending on the sapling type (own-rooted or grafted), 102.5-186.0 kg/da edible leaves were collected from two harvests. In general, saplings leaves were found to be smaller in size and delicate than matura vine. It is recommended that the leaves of saplings should be evaluated by vine sapling companies having permanent workers.

A field experiment was undertaken at Regional Agriculture Research Station, Nandyal, Andhra Pradesh for two consecutive years viz., 2018-19 and 2019-20 on Vertisols under rainfed condition to study the effect of different levels of nitrogen and topping on performance of bidi tobacco (Nicotiana tabacum L.) varieties. The treatments consisted of two varieties as main plots, three nitrogen levels as sub plots and three topping levels as sub sub plots in split split plot design and replicated thrice. The data pooled over two seasons revealed that significantly higher leaf length (47.6 cm), leaf width (21.3 cm) and cured leaf yield (2217 kg ha-1) were recorded with variety ABD 132 over other variety Nandyal Pogaku 1. Application of 140 kg N ha-1 recorded higher leaf length (47.7 cm), leaf width (20.9 cm) and cured leaf yield (2110 kg ha-1). The topping at 15 leaf stage recoded higher cured leaf yield (2147 kg ha-1) over other topping stages. Higher net returns (Rs 105544 ha-1) with BCR of 2.72 were recorded with ABD 132 over Nandyal Pogaku 1. Application of 110 kg N ha-1 recorded higher BCR of 2.55 whereas topping at 15 leaf stage recorded higher net returns (Rs 100275 ha-1) with BCR of 2.64. ABD 132 recorded higher nicotine (5.94%), lower reducing sugars (2.25%) and higher chlorides (1.61%) when compared to Nandyal Pogaku 1 (5.71%, 2.97% and 1.23% respectively). The levels of nitrogen and topping had non-significant effect on leaf chemical constituents. The interactive effect among various treatments had significantly beneficial effect on cured leaf yield of bidi tobacco and maximum cured leaf yield was obtained with ABD 132 with 140 kg N ha-1and topping at 15 leaf stage.

Variation among different traits along with their correlation were studied in twenty seven clones of Morus alba . The significant differences were found among clones with respect to various morphometric traits. Moderate phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability and genetic gain were recorded for green leaf yield, ramet height, leaf length, leaf width and basal diameter indicating that these characters can be more reliable for effective selection in future. Ramet height showed positive and significant correlation with basal diameter (0.5287), leaf length (0.4671), number of branches (0.6043), and green leaf yield (0.6893). Basal diameter, leaf length and leaf width also exhibited positive and significant correlation with green leaf yield i.e. 0.4705, 0.5714, 0.4813, respectively. Hence, these correlations can be useful in the indirect selection of the species.

Khaya senegalensis (Desr) A. Juss is a perennial deciduous tree which has many uses in developing nations. The population of the tree is rapidly declining due to no conservation efforts to prevent the species from endanger and extinction. At the moment there is dearth information on manure types required to raise healthy seedlings of the tree species in the study area. To conserve this genetic resource, germination and early growth rate experiment was carried out using seeds collected from three locations (eco-zones) (Alkaleri, Bauchi and Toro). Matured seeds of K. senegalensis were collected from mother tree stand in the three locations. One hundred and fifty seeds (150) from each location were sown in perforated polythene pots at an average depth of 2-3 cm. After germination i.e. 30 days after planting, different manures were applied to the seedlings. The experiment was laid out in a Completely Randomized Design (CRD) with three treatments, namely: poultry dung, cow dung and NPK manures; the experiment was replicated four times. Data on seeds germination variables of interest (seedling heights, number of leaves, collar diameter, leaf area, leaf width, leaf length and fresh weights) were measured. Seedlings height were measured using meter rule, collar diameters using a venier caliper, numbers of leaves were determined by manual counting the number of leaves on the seedlings, leaf area was measured by tracing leaves of seedling on a graduated graph sheet. Data collected on seed germination and early growth rate were subjected to descriptive statistics and inferential statistics (ANOVA). Where significant differences occurred, Tukey test was used to separate the means. Based on this finding, germination of seeds commenced after 10 to 14 days. Locations and manure types had significant effects on the mean heights, number of leaves, collar diameter, leaf area, leaf width, length and fresh weights of K. senegalensis seedlings in the study area. Thus, for species conservation and genetic heredity, seeds sourced from Bauchi eco-zone was the best with poultry manure as the best performed manure for the raising of K. senegalensis seedlings in the study area.

In the pedigree method of conducting an autogamous population of segregating plants, the genealogy of the progenies is registered. Although labor-intensive, these data are rarely used. One possibility of exploiting this information is to improve selection efficiency using BLUP (Best Linear Unbiased Prediction). In this study BLUP with genealogy inclusion was compared to the mean in the progenies evaluation conducted by the pedigree method. Progenies of crosses of the common bean lines BRS MG Talismã and BRS Valente in F4:6 and F4:7 were used. The 256 F4:6 progenies were sown in February 2005, in southeast of Brazil, in a 16 <FONT FACE=Symbol>´</FONT> 16 simple lattice design. The grain yield data were subjected to BLUP analysis with inclusion of genealogy. Based on this analysis and the mean, the 30 progenies with best and worst performance were selected. These 60 F4:7 progenies were classified in relation to the origin, i.e., selected by BLUP, mean, or BLUP and mean and coincident results were obtained. In the selection for best performance, the efficiency of BLUP was 2.4% higher than the mean. In the selection for the opposite extreme, BLUP analysis was however not advantageous. The progenies <FONT FACE=Symbol>´</FONT> environments interaction indicates the need for an evaluation of the progenies in different environments before beginning selection.

ABSTRACT: Leaf length (L), leaf width (W), and leaf area (LA) were measured from 100 leaves aiming to determine a simple linear equation (Y=a*X) to predict the leaf area of Commelina diffusa, an important weed infesting annual and perennial crops in Brazil and worldwide. Results indicate the equation LA=0.7*LW reliably estimates the leaf area of C. diffusa, after correlating LA with LW, and then validating that equation by analyzing four new 25-leaf samples.

Influences of irrigation frequency on the growth and flowering of chrysanthemum grown under restricted root volume were tested. Chrysanthemum cuttings (Chrysanthemum morifolium“Reagan White”) were grown in seedling tray which contained coconut peat in volumes of 73 and 140 cm3. Plants were irrigated with drip irrigation at irrigation frequencies of 4 (266 mL), 6 (400 mL), and 8 (533 mL) times/day to observe their growth and flowering performances. There was interaction between irrigation frequency and substrate volume on plant height of chrysanthemum. Plants grown in 140 cm3substrates and irrigated 6 times/day produced the tallest plant of 109.25 cm. Plants irrigated 6 and 8 times/day had significantly higher level of phosphorus content in their leaves than those plants irrigated 4 times/day. The total leaf area, number of internodes, leaf length, and leaf width of chrysanthemums grown in 140 cm3substrate were significantly higher than those grown in 73 cm3substrate. The numbers of flowers were affected by both irrigation frequencies and substrate volumes. Chrysanthemums irrigated 8 times/day had an average of 19.56 flowers while those irrigated 4 times/day had an average of 16.63 flowers. Increasing irrigation frequency can improve the growth and flowering of chrysanthemums in small substrate volumes.
