Field experiments were conducted for two seasons (2015-16 and 2016-17) to evaluate bio-rational insecticides against leaf miner (Liriomyza trifolii) damaging cantaloupes and it was found that among various insecticides viz. spinosad [email protected]/l, abamectin 1.9EC @0.3ml/l, fipronil 5SC@2ml/l, fipronil [email protected]/l, cyantraniliprole 10OD@ 1.8ml/l, triazophos 40EC@2ml/l, diafenthiuron 50WP@1g/l, novaluron 10EC@1ml/l, neem [email protected]/l, pongamia [email protected]/l, azadirachtin 1%EC @5ml/l, abamectin (1.03-2.33 mined leaves/10ft row) and spinosad (1.18-3.33 mined leaves/10ft row) in both the seasons prove to be highly effective in minimising the damage. All the treatments had significant effect on the yield as compared to control but among treatments they were non-significant in first season which was not the case in second season where highest yield was noted in spinosad (11.43t/acre) followed by azadirachtin(9.79t/acre) and abamectin (9.67t/acre). Though there was variation in yield within these treatments but they were statistically on par with each other. Similarly the treatments were on par with each other with respect to number of fruits per vine, fruit weight, TSS and number of seeds set per fruit. The overall findings indicate that the molecules viz., abamectin and spinosad can be recommended to control leaf miner in cantaloupes to achieve an appreciable yield.

Several population samples of Rubus idaeus subspp. strigosus Michx. (raspberries) were collected in British Columbia and northern Alberta and a number of characters were studied and compared with the cultivar Trent. Significant differences between populations were found for cane length, number of buds per cane, percentage of buds growing, number of inflorescences and flowers per bud, fruit and seed weight. There was a positive correlation between the total seed weight and the number of seeds, and between the total seed and fruit weight. No distinct types could be established based on location or elevation. None of the populations showed significantly better winter hardiness than the cultivar Trent, and although some had a specific character that was superior, none was found to have overall superiority.

Field experiments were conducted during 1982 to 1988 in Virginia to evaluate BAS 517, CGA 82725, clethodim, cloproxydim, fenoxaprop, fluazifop, fluazifop-P, haloxyfop, paraquat, quizalofop, SC-1084, sethoxydim, sethoxydim plus thifensulfuron, and terbacil for control of annual grasses in alfalfa. Herbicides were applied to alfalfa and grasses 2 to 30 cm in height after the first and/or second cuttings. Overall, the herbicides were highly effective in controlling fall panicum, giant foxtail, barnyardgrass, and large crabgrass. Alfalfa yields were not increased with herbicide treatments in several experiments. Only paraquat, applied later than recommended after cutting in one experiment, and sethoxydim plus thifensulfuron at one location reduced alfalfa yields.

ABSTRACT Knowledge about associations between traits is fundamental for plant breeding, since indirect selection can accelerate the development of promising genotypes. This study assessed the magnitude of associations between agronomically important traits in fisális (Physalis peruviana L). The experiment was conducted in Lages, Santa Catarina, and the treatments consisted of six fisális populations. The experiment was arranged in a randomized block design, with two replications and seven plants per plot. The correlations between traits were estimated based on the Pearson correlation coefficients and partitioned into direct and indirect effects through path analysis. Fruit weight was positively correlated with number of seeds (0.874), equatorial fruit diameter (0.738) and polar fruit diameter (0.672). By path analysis, number of seeds was identified as the trait with the highest direct contribution to fruit weight. The high phenotypic correlations between the equatorial and polar fruit diameters with fruit weight were mainly due to the indirect effect via number of seeds (0.505 and 0.459). The selection for heavier fisális fruits was strongly influenced by number of seeds, i.e., this trait should be taken into account for selection.

O objetivo do presente trabalho é caracterizar biometricamente os frutos e sementes de Passiflora cristalina Vanderplank & Zappi ocorrentes na região de Alta Floresta, Mato Grosso. Foram coletados em 2013 um total de 100 frutos maduros de 15 genótipos e destes foram selecionadas 300 sementes aleatoriamente. Os frutos foram analisados quanto ao comprimento, largura, espessura, peso, espessura da casca, o peso da polpa, o peso das sementes/fruto, número de sementes/fruto e teor de sólidos solúveis. As sementes foram avaliadas em relação ao comprimento, largura, espessura e índice de volume. As características biométricas foram analisadas mediante distribuição de frequência calculando-se o coeficiente de correlação de Spearman e o nível de significância através do teste T. O comprimento do fruto correlacionou-se positivamente com a largura e peso do fruto, espessura da casca e com peso das sementes, não havendo uma correlação com o número de sementes por fruto. Houve uma ampla distribuição de frequência das características avaliadas nos frutos, com exceção do peso das sementes. A alta variação fenotípica encontrada para a maioria das características avaliadas nos frutos e sementes de P. cristalina revela que a espécie tem divergência genética a ser utilizado em programas de seleção e conservação de recursos genéticos.Palavras-chave: divergência genética, maracujá, recursos genéticos. BIOMETRIC ANALYSIS OF FRUITS AND SEEDS OF Passiflora cristalina Vanderplank & Zappi ABSTRACT: The present work has presented the fruits and seeds of Passiflora cristalina Vanderplank & Zappi occurring in the region of Alta Floresta, Mato Grosso. A total of 100 mature fruits of 15 genotypes were collected in 2013 and 300 seeds were randomly selected. The fruits were inert to the length, thickness, thickness, weight, bark thickness, pulp weight, seed/fruit weight, number of seeds / fruit and soluble solids content. The seeds were evaluated for length, width, thickness and volume index. The biometric characteristics were analyzed with the calculation frequency calculated with the Spearman correlation coefficient and the level of significance throughout the T test.

In a semiarid Mediterranean site in central Spain, field experiments were conducted on a Calcic Haploxeralf (noncalcic brown soil), which had been managed with three crop rotations and two tillage systems (no-tillage and conventional tillage) since 1987. The crop rotations consisted of barley→vetch, barley→sunflower, and a barley monoculture. The study took place in two growing seasons (1992–1994) to assess the effects of management practices on the weed seedbank. During this period, spring weed control was not carried out in winter crops. In the no-tillage system, there was a significant increase in the number of seeds of different weed species: anacyclus, common purslane, corn poppy, knotted hedge-parsley, mouse-ear cress, spring whitlowgrass, tumble pigweed, venus-comb, andVeronica triphyllos.Conversely, the presence of prostrate knotweed and wild radish was highest in plots under conventional tillage. These results suggest large differences in the weed seedbank as a consequence of different soil conditions among tillage systems, but also the necessity of spring weed control when a no-tillage system is used. With regard to crop rotations, the number of seeds of knotted hedge-parsley, mouse-ear cress, and spring whitlowgrass was greater in the plots under the barley→vetch rotation. Common lambsquarters dominated in the plots under the barley→sunflower rotation, whereas venus-comb was the most frequent weed in the barley monoculture. Larger and more diverse weed populations developed in the barley→vetch rotation rather than in the barley→sunflower rotation or the barley monoculture.
