Productive System

Los rendimientos de chile jalapeño en Quintana Roo son bajos y el tamaño del fruto es una limitante en la comercialización, el cambio del sistema de producción puede incrementar la competitividad de la cadena de valor del chile jalapeño, una estrategia para el mejoramiento de la productividad y calidad de fruto es la utilización de material genético con mejores características.Los objetivos del trabajo fueron conocer la calidad del fruto que se obtiene en Quintana Roo con las variedades criollas utilizadas y evaluar el potencial de rendimiento y la calidad de fruto de variedades comerciales en sistemas de agricultura protegida.En diciembre de 2019 se hizo un muestreo de frutos en parcelas del sur de Quintana Roo, los frutos colectados se evaluaron por forma y el tamaño. De las colectas se seleccionaron los frutos que tenían buenas características de acuerdo con los productores, se extrajo la semilla para establecer estos materiales en enero de 2020 en invernadero, se evaluó la forma y tamaño del fruto y se compararon con las características de los frutos colectados.  En febrero de 2020 se evaluaron 7 variedades comerciales en invernadero, se evaluó el rendimiento en toneladas por hectárea, tamaño de fruto y color de fruto.Se encontró que la producción de chile jalapeño en Quintana Roo presentó una amplia variación en la forma del fruto y su clasificación por tamaño fue de frutos medianos y chicos.  La calidad del fruto de los materiales criollos cultivados a cielo abierto bajo condiciones de temporal no mejoró al cambiar su cultivo a invernadero en condiciones de riego. Las variedades comerciales evaluadas presentaron uniformidad en la forma del fruto y superaron en tamaño a los frutos procedentes de los muestreos de las parcelas de Quintana Roo. Mixteco y Orizaba fueron las variedades más productiva (21 ton/ha).

Chemical Disinfection

This study aimed to identification of an ecological alternative for the chemical disinfection of soil in the greenhouses from Romania. Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops in the world. The carbohydrate, vitamins, salts of important mineral elements and organic acids content of tomato fruits is very important. Tomato crops are very sensitive to climatic vagaries, so fluctuation in climatic parameters at any phase of growth can affect the yield and the fruit quality. Grafting on Solanaceae is a method which has improved and spread quickly during the past years, a similar approach to crop rotation, a practice meant to increase productivity, resistance or tolerance to biotic and abiotic stress factors and at increasing fruit quality. The research was conducted in a glass greenhouse of the Horting Institute, Bucharest, Romania. The biological material used was a Romanian tomato hybrid (Siriana F1), a Dutch tomato hybrid (Abellus F1) and four rootstocks, a Dutch tomato hybrid (Emperador F1) and three Romanian tomato cultivars (L542, L543 and L544) obtained from the Research and Development Station for Vegetable Growing, Buzău, Romania. The rootstocks have had resistance to biotic stress factors (soil diseases and pests) and the chemical disinfection of soil has was eliminated. The result of this research are presented in this paper.

La desnutrición es un problema que afecta el crecimiento, desarrollo y salud en general, especialmente de los niños menores de cinco años y mujeres embarazadas. En México, los indicadores de bajo peso y talla señalan una reducción de 8 y 13.3 %, respectivamente, entre 1988 y 2012. A pesar de las intervenciones de salud pública la prevalencia de baja talla continúa siendo un importante problema de salud pública (13.6 % en promedio), especialmente en zonas rurales y urbanas marginales. La biofortificación de cultivos como maíz (Zea mays L.) con zinc es una forma de contribuir a combatir la deficiencia de este micronutriente, sobre todo en estados donde se observa una importante producción y un alto consumo per capita del grano (cerca de 200 kg/año). El objetivo del presente trabajo fue identificar áreas con mayor potencial para la introducción de maíces biofortificados con zinc; para ésto, se determinó un Índice de Priorización para Biofortificación (IPB) y las Condiciones de Intervención para Biofortificación (CIB). Los dos parámetros fueron determinados mediante la estimación de tres índices: producción, consumo y deficiencia de zinc. El IPB constituye una media geométrica de los tres índices, mientras que CIB establece los parámetros de atención para la biofortificación. Los resultados tanto del IPB como CIB indican que las áreas con prioridad elevada para biofortificación son Chiapas, Oaxaca, Guerrero, Hidalgo y Puebla. Las áreas establecidas con prioridad media son Nayarit y Durango, mientras que Quintana Roo fue determinada como de prioridad baja.

Aim. To evaluate the composition and breeding potential of a gene poolcollection of sweet cherry varieties of M.F. SydorenkoMelitopolResearch Station of Fruit Growing of the Institute of Horticulture, NAAS of Ukraine. Result and Discussion.The results of studying the morphological, economic and biological features of sweet cherry (Cerasusavium L. Moench) varieties from the gene pool collection of MelitopolExperimental Station of Horticulturenamed after M.F. Sidorenko of the Institute of Horticulture of NAAS are presented. The history of the collection creation and the genealogy of modern Ukrainian varieties were analyzed. We found that they were the 1st and 2nd generations of traditional Western European varieties. Major sweet cherry varieties that had been most often used in developing modern Ukrainian assortment, were identified. Analysis of the collection showed that 111 accessions of 129 were varieties bred in Melitopol, 40 of which are officially registered.The other accessions are elite forms, which failed the state variety trials or are being tested according to the competitive design. Among the latter, promising forms (candidates for varieties and pre-breeding forms) were distinguished, as they are sources of valuable economic traits. It was determined that the morphogenic process had contributed to the diversity in fruit quality features, which enabled building up a trait collection of sweet cherries for 20 traits with 82 levels of their expression. However, morphogenesis almost did not affect the growth power, fructification nature, generative organs, fructification time and resistance to diseases, therefore there are no significant differences in these features between the collection accessions bred at Melitopol Experimental Station of Horticulture named after M.F. Sidorenko of the Institute of Horticulture of NAAS. Most of the varieties grown on Magalebian cherry plantlet have extensive crowns, bear fruit on "May bouquets" and, after one-year growth, are winter hardy, tolerant to drought, moderately and highly resistant to spur blight and leaf spot as well as self-infertile. On this parent stock, most of the varieties come into fruition after 5-6 years and quickly increase their yields. It was established that enrichment of the gene pool collection with valuable introduced accessions and their wide involvement in hybridization were currently the key objectives aimed at expansion of morphogenesis limits to obtain competitive varieties with high adaptability, productivity and marketability. Conclusions. Modern Ukrainian varieties are the 1st and 2nd generations of traditional Western European varieties. German variety Drogansgelbeknorpelkirsche (DroganaZhyoltaya) with its clone Napoleon Belaya and Russian-Ukrainian variety Valeriy Chkalov were the most actively used in their development. 86% of the gene pool collection of MelitopolExperimental Stationof Horticulture named after M.F. Sidorenkoof the Institute of Horticulture of NAAS are varieties bred in Melitopol differing mainly in ripening time and fruit quality. The collection contains released varieties, a number of sources of valuable traits and, as a tool for the effective implementation of modern breeding programs, requires enrichment with varieties of other eco-geographical groups.
