Heterosis for quantitative characters in 39 cucumber genotypes (19 parents and 20 F1 s) were investigated at the farm of Department of Genetics and Plant Breeding in Bangabandhu Sheikh Mujibur Rahman Agricultural University during March-November, 2013. Analysis of variance revealed highly significant differences among the parents and hybrids for 19 characters studied. Considerable coefficient of variation were observed for branches per plant, flesh thickness, placental thickness, fruit length ,fruit width, male and female flowers per plant, leaf length, leaf breadth, vine length, fruits per plant , fruit yield per plant indicating the scope of selection for those characters. The characters like branches per plant, male and female flowers per plant, fruit length, fruit weight, fruits per plant, fruit yield per plant contributed the maximum variability towards divergence among cucumber genotypes. Heterosis study depicted that the crosses Sobujsathi × Baromashi, Sobujsathi × Khira, Himaloy × Khira, exhibited significant positive heterosis for 50 % female flowering; Himaloy × Baromashi, Baromashi× Greenking for fruit length; Baromashi × Hero, Yuvraj × Khira for single fruit weight. Where Sobujsathi × Baromashi, Shila× Khira , Modhumoti × Hero and Modhumoti × Khira exhibited significant positive heterosis and heterobeltiosis for yield per plant. The highest positive heterotic effect for no. of fruits per plant was observed in Modhumoti × Baromashi (20%). The highest heterobeltiosis effect was found in hybrid Himaloy × Yuvraj (24.5%) followed by Sobujsathi× Khira (11.2 %), Modhumoti × Baromashi (10.0 %). Four crosses exhibited significant positive better parent heterotic effect for this trait and the combination Sobujsathi × Baromashi had the maximum heterosis on yield (47.6%). The maximum heterobeltiosis effect was found in Shila × Khira (27.73 %) followed by Modhumoti × Hero (15.14%) and Modhumoti × Khira (10%) for fruit yield.Bangladesh J. Agril.

Twenty one genotypes of pumpkin (Cucurbita moschata L.) were evaluated to measure the variability among the genotypes for several characters, estimate genetic parameters, association among the characters and their contribution to yield. There was a great deal of significant variation for all the characters among the genotypes. High variability was observed in number of female flowers/plant, number of male flowers/plant, single fruit weight and fruit yield/plant. All the characters except days to first male flowering and days to first female flowering showed high heritability along with high genetic advance in percent of mean. The positive and strong association of number of female flowers/plant (rg=0.918, rp=0.839), number of male flowers/plant (rg=0.687, rp=0.638), fruit length (rg=0.691, rp= 0.520), fruit breadth (rg=0.518, rp=0.420) and single fruit weight (rg=0.492, rp= 0.431) with fruit yield/plant revealed the importance of these characters in determining fruit yield/plant. On the other hand, days to first male flowering (rg = -0.623, rp = -0.550) and days to first female flowering (rg= - 0.689, rp= -0.543) correlated significantly and negatively with fruit yield/plant. The path co-efficient analysis revealed that the highest positive direct effect was recorded in number of female flowers (0.887) to fruit yield and high direct effect was found in case of days to first female flowering (0.798). Fruit breadth was observed to have the highest positive indirect effect (0.899). In case of fruit length (0.381) and single fruit weight (0.398), the significant positive correlation with fruit yield/plant was observed because of the combination of the direct and indirect effects of fruit length and single fruit weight to fruit yield/plant. Overall, the results indicated that days to first female flowering, number of female flowers, fruit length, fruit breadth and single fruit weight can be used as useful selection criteria to increase fruit yield/plant in pumpkin.Bangladesh J.

Aims: The experiment aimed to investigate the effect of seasons (early raining and late raining) and mulching materials (Black polyethylene, White polyethylene, Grass-mulch and control) on marketable fruit yield of cucumber. Study Design: The experimental design was a 4 x 4 factorial laid out in a randomized complete block design (RCBD) with three replications. Data were collected on plant morphology and fruit components; number of leave, vine length, branch number, tendril number, stem diameter;  number of fruits per plant, fruit length, fruit circumference, fruit weight, number of marketable fruits per plot and number of non-marketable fruit per plot and fruit yield per plot (converted to per hectare). Place and Duration of Study: The present study was carried out at Teaching and Research Farm of Obafemi Awolowo University (OAU), Ile-Ife, Nigeria (located on longitude 04º33lE and latitude 08º28lN at 244 m above sea level) during the growing seasons of 2017 and 2018. Methodology: The data collected were subjected to analysis of variance (ANOVA) using (SAS, 2003 version). Means of significant treatments were separated using Duncan`s Multiple Range Test (DMRT). Results: The obtained results revealed that seasons and mulching materials had significant effect on some of the parameters investigated. Late season significantly enhanced the fruit length, fruit weight and total fruit yield when compared with the early seasons. The mulching materials, black polyethylene mulching materials significantly enhanced the morphology and some of fruit components; fruit length and fruit weight while white plastic mulch significantly improved the number of fruit per plant, fruit diameter and total yield of cucumber at both early and late seasons followed by grass-mulch. However, control consistently produced the highest number of non-marketable fruits when compared with other treatments investigated.  Conclusion: Therefore, planting of Poinsett76 variety towards the ending of raining seasons with the application of white plastic mulching is highly recommended for the small holder farmers.

Date palm is unisexual, being either male or female. Male and female flowers grow on buds called Spathe, which opens naturally when fully mature. It is easy to identify the male and female flowers. Under the method of manual pollination, pollen from a male flower is smeared over female flowers. The pollen variety and pollination time have important effects on date palm fruit set, yield and quality. This experiment was carried out to study the effect of date pollinizer variety and pollination time on fruit set, growth and development of Medjhol date palm variety, in date palm garden of date palm and tropical fruit research institute of Iran during three years from 2009 to 2011. The trail was randomized complete block design in factorial manner with three pollen variety as Ghaname, Vardy, and Samesmave, two pollination time as 1-3 days before or after spathe opening and four replication. The results showed that the Vardy pollen had significant effects and increased the fertility percent and fruit yield, rather than two other pollen varieties. The pollen variety had no significant effects on fruit quality as total sugar, acidity, and bricx. The pollination time before spathe opening significantly increased fertility percent, decreased fruit weight and date palm yield. Finally the pollen variety and pollination time interaction effects showed that, application of Vardy pollen from 1-3 days after spathe opening with the most production date palm yield, equal 19.9 kilogram per any date palm trees, so this treatment is the best and are recommended.

Twelve exotic cultivars of cucumber (Cucumis sativus) were grown to assess the presence of variability for desired traits and amount of variation for different parameters. Genetic parameters, correlations, partial correlation and regressions were estimated for all the traits. Analysis of variance revealed significant differences among entries for all the characters. The estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were high for yield per plant, fruits per plant, fruit weight and fruit length. Broad sense heritability estimates for various traits ranged from 42.26 to 89.55%. Fruit yield per plant showed high significant positive correlation with fruits per plant, fruit weight, flesh thickness, fruit diameter and leaves per plant. Partial correlation was significant for fruits per plant and indicated these traits contributed over 70% to total fruit yield. By variability, correlation and regression analysis it was concluded that more fruits per plant and more fruit weight are major yield contributing factors in selecting high yielding cucumber cultivars.DOI: http://dx.doi.org/10.3329/bjpbg.v25i1.17008

Forty two hybrids generated by crossing three testers with fourteen lines were studied along with parents for studying heterosis and gene action for days to first flowering, days to 50 percent flowering, fruit weight, fruit length, plant height, number of seeds per fruit, 100-seed weight and fruit yield per plant during rainy season and summer season of 2002-03 at Department of Horticulture, Indira Gandhi Agricultural University, Raipur, Chhattisgarh, India. The most heterotic combinations were VRO-6 x Parbhani Kranti, VRO-4 x Parbhani Kranti, Daftari-1 x Arka Abhaya and Kaveri Selection x Ankur Abhaya for fruit yield per ptant. The sca variances for days to fruit flower, days to 50 percent flowering, fruit weight, fruit length, plant height, number of seeds per fruit and 100-seed weight were higher than so gca variance so there is a preponderance of non-additive gene action. The gca variances was greater than sca variances for fruit yield per plant indicating preponderance of additive gene action for this trait. Overall, the results discussed above are quite indicative of the fact that hybrid okra has great potentialities of maximizing fruit yield in Chhattisgarh plains.DOI: http://dx.doi.org/10.3329/bjar.v32i3.544Bangladesh J.

Abstract Cucumber (Cucumis sativus L.) is an important vegetable crop, rich in vitamins and minerals and eaten fresh as a dessert. Its fruit yield is relatively low, though could be improved through knowledge of character association with it and selection of desirable materials for improvement programmes. Fifteen cultivars of Cucumber were evaluated at two locations (Abeokuta and Ibadan), South West, Nigeria in a randomized complete block design with three replicates in order to determine heritability, correlation, direct and indirect effects of characters on fruit yield. Data collected on agro-morphological characters were subjected to analysis of variance, estimates of heritability, correlation, and path analysis. Significant variations (p <0.05) were observed in the cultivars. High heritability estimates (>90%) was observed for fruit length at both locations. A significant phenotypic and genotypic correlation was observed between fruit yield and fruit weight. Number of days to 50% flowering and fruit width could also be selected directly for improvement of fruit yield in cucumber.

The study was tested the technical feasibility of bagging eggplant fruits during production to protect them against Eggplant fruit and shoot borer (EFSB) following randomized complete block with 6 treatments. Highest number of marketable fruits per plant was produced by imported white bag (12.33), which was followed by butter paper bag (10.67). Maximum aborted fruit was obtained from the imported brown bag (23.33%) and HDPE bag (20.00%). The highest average fruit weight (363.33 g) was obtained from fruits bagged with Imported white, while maximum fruit length and fruit diameter was also produced from imported white bag (15.27 cm and 11.23 cm, respectively). Zero percent damage by eggplant fruit and shoot borer was produced by imported brown bag, imported white bag and butter paper bag, while higher infection was observed in open fruit (control) (17.70 %), HDPE bag (11.70 %). Bagging eggplant fruit produced 38.78 to 58.20 t/ha, while open fruit (control) produced only 35.66 t/ha. The highest calculated fruit yield 58.20 tons/ha was estimated from imported white bag and other bagging fruits were local brown bag (46.74 t/ha), HDPE bag (45.00 t/ha), butter paper bag (43.23 t/ha). The bagging of eggplant fruits with imported white bag and butter paper bag were more effective in reducing damage by eggplant fruit and shoot borer than the other bagging treatments and the control. These two treatments produced higher number of consumers preferred fruit, without negative effects on the color of the skin, fresh weight and fruit abortion, thus resulting in higher economic gains.

Abstract Burmese grape (Baccaurea sapida Muell. Arg.) belongs to the family Euphorbiaceae, is a minor underexploited fruit crop grown wild as well as under cultivation in Nepal, India, Myanmar, Bangladesh, China, Thailand, for fresh consumption. It is a dioecious plant and reported to have an excellent nutritive value, but mainly grown in homestead condition mostly in neglected ways without fullest utilization of its potentiality. The present study was aimed to understand and first time characterize the germplasm nature, and details of flowering and fruiting system of Burmese grape. The experiment showed that, tree growth habit and crown shape of all the accessions surveyed were semi erect and irregular, respectively. The flower bud differentiation in male and female accessions started during the mid February and anthesis occurred from mid March for both male and female accessions. The colour of the male flowers varied from yellow to green yellow shades while the colour of the female flowers varied from yellow to yellow green and green yellow shades. Significant variation of leaf area, number of flowers per panicle, length and diameter of inflorescence, fruit length, breadth, weight etc. were observed. The variation present on fruit length (2.81 cm to 3.80 cm), fruit weight (12.25g to 22.95g), pulp percentage (49.82% to 65.33%), total soluble solids (9.00º to 13.10ºBrix), tritable acidity (0.73mg to 1.28mg/100g fruit pulp) and ascorbic acid content ranged from (23.18mg to 57.80mg/100g fruit pulp) suggest suitable selection method for identification of promising Burmese grape genotypes.

Genetic divergence among nineteen inbred lines of pumpkin (Cucurbita moschata Duch Ex Poir) was estimated through principal component analysis and Mohalanobis’s D2 analysis. Inbred lines were grouped into five clusters. Cluster I, II, III, IV and V were composed of five, three, four, six and one inbred lines respectively. Maximum inter cluster distance was observed between the cluster III and V (72.69) followed by the cluster I and V (63.33). Minimum inter cluster distance was observed between cluster II and IV (10.64). The mean value of cluster III indicated the importance of days to first male and female flower open, node order to 1st female flower open and TSS.  Cluster IV showed the importance of days to first female flower open, fruit diameter, cavity diameter, flesh thickness and average fruit weight. Similarly, cluster V indicated the importance of yield per plant, fruits per plant and fruit length. Days to first male and female flower open, fruit length and cavity length had the highest contribution towards divergence among the inbred lines. Considering the magnitude of cluster distance, cluster means for different characters and contribution of characters towards divergence, the inbred lines from clusters I, III and IV could be selected as parent for hybridization program.
