Open and Closed Breeding of Crops

Peizhan Tian
Mutual suiting relationship between breeding way and widening germplasm was first analyzed. Source of utilization germplasm was the more the widener from only using variation in a variety to among family even bigger scope, especially transformation gene breeding could use superfine gene of living things in the world and create germplasm resources that could not obtain in conventional breeding. Secondly contradiction and its movement between ecological and yield ability character, among yield abi...

Socioeconomic and Ecological Impact Analysis of Rubber Cultivation in Southeast Asia

Chansack Vongkhamheng, Jianhua Zhou, Mukete Beckline, Sythud Phimmachanh
In this paper, we aimed at examining the role of natural rubber (Hevea brasiliensis) cultivation as a source of income for rural communities as well as a potential source of ecological damage. We reviewed existing scientific literature and data sources on natural rubber cultivation particularly in south East Asia. We observed that, the latex from the lower part of the trunk has a high commercial value which can assist rural communities in socioeconomic development; the trunk is a source o...

Floristic Diversity and Ethnobotanical Uses of Vedhagiri Hills in Bhavani, Erode District, Tamil Nadu

Saranya Ravi, Rajendran Arumugam, Sarvalingam Ariyan
Background: The present study was undertaken to enumerate the floristic composition of Veddhagiri hills, the Southern Western Ghats of Erode district. It becomes essential to analyze the diversity statically to find out the distribution of plants species in various families. Material and Methods: Several field trips were made from September 2013 to March 2014, covering different seasons, in order to know the phenology of the plants. Results: A total number of 135-species under 40-families with 1...

Enhancement of Artemisinin in Artemisia annua L. through Induced Mutation

Mutai Raymond, Kinyua Miriam, Kiplagat Oliver, Mutai Edwin, Kimno Stephen
Artemisia annua is the source of artemisinin, an antimalarial drug which is effective against multidrug-resistant strains of plasmodium, the malarial parasite. Malaria has serious effects on morbidity and mortality thus negatively impacting on agricultural production and food security. Although artemisinin has been found to be a useful medicine; its production is very low in comparison with what is actually needed to treat the worldwide threat of malaria. On the other hand, the lower cont...

Management of the Banana Cavendish Giant (AAA) in Postharvest for Increasing Its Shelf Life

Prisma Deyanira Zevada Reyes, Leopoldo Partida Ruvalcaba, Vicente Alvarez Mares
This research is conducted to determine if the shelf life of bananas increases when it is stored in closed polystyrene containers and placed in refrigerated camera with cool temperatures. Bananas were acquired when they were in greenness rates 1, 2, 3 and 4. In the refrigerator it is applied temperatures of 10℃ - 12℃. By each maturity index (1, 2, 3 and 4), the fruits were packaged in four containers (repeats), which were opened every five days to observe signs of sensory maturity. The response ...

Canopy Temperature and Yield Based Selection of Wheat Genotypes for Water Deficit Environment

Md. Mahfuz Bazzaz, Qazi Abdul Khaliq, Md. Abdul Karim, Abdullah Al-Mahmud, Md. Shawquat Ali Khan
The experiment was conducted with thirty-five wheat genotypes at the research field of the Department of Agronomy of the Bangabandhu Sheikh Mujibur Rahman Agricultural University from November 2011 to March 2012 to screen out the wheat genotypes for drought tolerance of thirty-five wheat genotypes under water deficit condition. The experiment was carried out in a split- plot design comprising two water regimes in main plot and thirty-five wheat genotypes were placed randomly in sub-plot with thr...

Planting Time Effects of Top-Shoot Cutting on Yield and Grade for Rapid Seed Potato Multiplication

Md. Abdullah Al Mamun, Abdullah Al Mahmud, Md. Shawquat Ali Khan, Md. Altaf Hossain, Mohammad Zakaria
Top-shoot cuttings were evaluated as planting material with different planting time for rapid multiplication of potato. Plants produced from top-shoot cuttings planted on 25th November (T3) produced higher mean tuber yield (32.95 tha﹣1) than December planting. Total yield of potato increased 122.8% from early one source crop plants due to taking two times cutting and it was 89.7 % from late one source crop plants. Seed tuber yield increased 167.89% and 95.33% in ...
