“…BRPCU-7 (3.63 o Brix) had the highest TSS, followed by BRPCU-6 (3.47 o Brix) and . Nagamani et al, 2019;Kumar et al, 2019;Hochmuth et al, 2004 observed considerable differences for respective features while evaluating their materials in previous studies on evaluation of parthenocarpic cucumber hybrids under shade net situation. The heritable (genetic variance) and nonheritable (environmental variance) components of the phenotypic variance of the characteristics were separated (Table 3).…”

An experiment was conducted during Kharif, 2018 to evaluate the mean performance and to find out the nature and extent of genetic variability among eight inbreds of parthenocarpic gynoecious cucumber genotypes under naturally ventilated polyhouse situated at polyhouse complex of department of Horticulture (Vegetable and Floriculture), BAU, Sabour, Bhagalpur, Bihar of Eastern India. The experiment was laid out in randomized block design with three replications. Data were taken on six competitive plants for 13 growth and yield attributing traits, including total soluble solids (TSS) and per cent disease index for downy mildew (PDI). Among eight cucumber inbreds, BRPCU-1 showed earliness in respect of days to first female flower, node to first female flower and days to first fruit harvest, and disease tolerance to downy mildew. However, inbreds BRPCU-3, BRPCU-5 and BRPCU-7 were high yielders in fruits per plant and yield per plant. Non-additive gene effects were manifested for most of the earliness, while additive gene effect was observed for yield and fruits per plant.

“…The crop is grown for its tender fruits which have high water content and are consumed raw as salad (Sumathi et al, 2008). It is a rich source of vitamin B and C, carbohydrates, and minerals like calcium and phosphorus (Nagamani et al, 2019). Parthenocarpic cucumber grown in protected environment is vulnerable to a diversity of insect pests.…”

The use of chemical pesticides to control two spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) in various crops leads to the development of various problems viz., residue in sprayed crop, pest resistance, pest resurgence and environmental pollution. It was necessary to find some microbial biorationals may represent an effective alternative management tactic which is environmentally safer option also. So, during this study entomopathogenic fungi (EPF) and botanical pesticides were tested at different concentrations for the management of eggs and active stages of T. urticae infesting parthenocarpic cucumber grown under polyhouse. Among these biorationals, spray of Neem Baan at 10 and 15 ml/l resulted in significantly higher level of reduction on two spotted spider mite population (88.5 to 91.8% in egg and 86.6 to 90.9% in active stage of mites after 3rd spray, respectively) than with EPF. Among the EPF, Lecanicillium lecanii (Zimmerman) Viegas and Beauveria bassiana Balsamo (Vuillemin) (at 10 & 15 ml/l (82.0 to 87.0% in egg and 79.2 to 84.1% in active stage of mites)) was found to be more effective than Metarhizium anisopliae (Metschnikoff) Sorokin (at 10 & 15 ml/l (77.0 to 82.4% in egg and 76.4 to 80.4% in active stage of mites after third spray, respectively)) in reducing different life stages of T. urticae on cucumber. Results suggest, as Neem Baan 1% spray was found to increase growth and yield of sprayed plant along with controlling T. urticae, it can act as a good alternative for the pesticide spray because spray of pesticide majority time leads to residue problem, pest resistance and pest resurgence problem.
