With an objective to conserve the best local types for future generation and purpose of these trees protected from extinction due to national high ways road expansion by the government and local bodies. The collection was made in and around our college about 15 km radius found small tree uniformly good Moringa types are cultivating as kitchen garden tree in front and backside of the home where tribal areas of Tiruvannamalai district. Continues concentration of tagged trees for three years study related to growth habits, fruiting capacity, taste of fruits and market value of fruits, the green pod yield assessment was recorded from the marked trees. Among the tagged trees over three years study, the Vahavachanur 1. Perunduraipattu3, Michealpuram 5, Moongilduraipattu 1 and Vanapuram 3 trees qualities are better for rganoleptically culinary vegetable purpose and also Vzhavachanur1 tree found offseason bearing than other areas trees inclusing selected trees.

Intraspecific Hybridization between Non-spiny and Spiny Brinjal for Developing Non-Spiny Brinjal without Deletion of Spiny Brinjal Qualities

An objective to develop Non-spiny brinjal without deletion of quality characters of spiny brinjal for consumers preference and also avoid hitting of spines to harvesters. Spiny brinjal (VRM-1Mullukathiri) is a pure line selection from Elavambadi village of Vellore district of Tamil Nadu. Spines are present in the leaf, stem and calyx of the fruit. VRM-1Mullukathiri is high yielding (30-35 t/ha-1) and most suitable for North-Eastern Zone of Tamil Nadu. From this cross of Non-spiny x spiny cross combination, the VMB-012-008 was identified for big size fruit with green colour fruits.

Development of Mungbean yellow mosaic virus Resistant Genotypes in Mungbean through Interspecific Crosses of Wild Vigna Species

Mungbean Yellow mosaic disease is a main destructing viral disease in mungbean caused by Mungbean yellow mosaic virus (MYMV) which leads to severe sometime 100 percent yield reduction and it necessitates for developing MYMV resistant lines. The present investigation was carried out with an objective of evolution of MYMV resistant progenies through incorporating wide genes of same genera. An attempt was made between V. radiata x V. umbellata crosses. This agroinoculation technique was employed to examine the F2 individuals, which were derived from a cross between VMGG012-005 (Moderately susceptible) x VGGru1 (resistant homozygous advanced line from Vigna radiata x Vigna umbellata derivative used as MYMV donor) to screen for the MYMV resistant progenies. In the field condition, MYMV infection can be evaluated by MYMV disease rating scale (1-9).

Supporting Innovation in Integrated Agroecological Production Systems, Employment Creation and Youth Engagement in Productive Processes in Jamaica, Saint Lucia and Trinidad and Tobago

Agriculture must meet the challenges of hunger and malnutrition against a backdrop of population growth, increased pressure on the environment and biodiversity and the challenges associated with climate change, poverty and urbanization. While past efforts focused on increasing agricultural production, today’s challenge is to tackle root causes through transformative changes on how we produce, distribute and consume nutritious food that contributes to healthy diverse diets. Agroecology is a promising holistic approach to support this transition to sustainable agricultural and food systems.

Performance of Soybean Genotypes under Rhizobia Inoculation across Three Agro Ecologies of Nigeria

There is need to improve soybean yield potentials per unit area in the tropics, at least to the world average productivity level. To achieve this, attention has to be paid to the selection of high yielding and stable genotypes through plant breeding improvement programmers. Twenty four soybean lines were investigated across three agro ecological zones in Nigeria to determine their productivity. In each of the sites, the experiments were laid out in randomized complete block design with three replications. Data were collected on growth and yield parameters.

Repellent Activity of Bark Extracts of Zanthoxylum heitzii Against the Malaria Vector Anopheles gambiae

The objective of this study was to evaluate crude extracts of leaves, bark and seeds of the plant Zanthoxylum heitzii using hexane, ethyl acetate, ethanol, water/ethanol and water solvents, and to evaluate the extracts for repellence to the malaria mosquito, Anopheles gambiae.

Progress of Microalgal Biodiesel Research in Pakistan

Excessive use of fossil fuels has led to severe energy calamity and environmental pollution in the world. The effect can be mitigated by shifting from conventional fuels to biofuel which may become a replacement of fuels such as diesel, gasoline and Compressed Natural Gas (CNG). Algal biomass is considered as one of the most promising and emerging sources of biodiesel production. Technologies related to biodiesel production using algal biomass have gained initial foothold in Pakistan but have failed miserably in gaining necessary momentum due to lack of government support to technology. The aim of this study is to indicate the progress and future perspectives of biodiesel production in Pakistan through microalgae. The study indicates that a microalgae is one of the best candidates for biodiesel production in addition to other energy crops like Jatropha, Castor and Pongamia Pinnata. There is a need to expeditiously develop biodiesel technology using local resources to lower the burden of imports on country’s economy while also bringing security of energy resources.

Natural Variation in Wild Gossypium Species as a Tool to Broaden the Genetic Base of Cultivated Cotton

Cotton is the world’s most important natural textile fiber and a significantly growing source of food stuff, oil and feeds. Among the 53 Gossypium species, only 4 are cultivated, with G. hirsutum and G. barbadensecomprising over 90% of the total cotton cultivation area worldwide. The extensive use of only a few closely related genotypes of cotton, coupled with the widespread adoption of transgenic cultivars, has greatly reduced the genetic base of the crop. This genetic uniformity makes cotton highly vulnerable to emerging biotic and abiotic challenges. Future breeding targets have to seriously consider infusing novel genetic variation into the gene pool of cultivated cotton that can buffer the crop against agro-environmental challenges brought about by shifts in climate. The wild Gossypium species hold a tremendous amount of untapped genetic diversity that can be exploited to broaden the genetic base of cotton. This review highlights the important agronomic traits that have been reported in wild Gossypiumspecies and discusses the various pre-breeding strategies that have been utilized to incorporate genomes of wild Gossypium in cultivated cotton. Genetic and molecular studies towards understanding Verticilliumwilt resistance and salt tolerance in wild cotton relatives are presented in brief.

Correlation and Path Coefficient Analysis in Mid-Altitude Sesame (Sesamum indicum L.) Germplasm Collection of Ethiopia

The present study was aimed to gather information on genetic association of traits with respect to seed yield and its components. The genotypes were planted in 9 × 9 simple lattice designs at Melkassa Agricultural Research Center, Ethiopia, during the 2014 cropping season to determine the nature and extent of phenotypic and genotypic correlation and path coefficient analysis among 13 quantitative traits. Analysis of variance revealed significant difference among genotypes for all traits studied. Mean performance of genotypes revealed that the highest mean seed yield/plant (8.6g) recorded for Oromia-22 and the lowest mean seed yield/plant (2.6g) for Oromia-9; with overall mean of 5.33g/plant.
