Conventional plant breeding is the development or improvement of cultivars using conservative tools for manipulating plant genome within the natural genetic boundaries of the species which is aimed at producing plant that are superior in terms of quantity and quality than the pre-existing ones. However, the success of conventional plant breeding depends completely on the fertility status of the two parent plants involved in the hybridization program. Plantain and Banana are monoecious, sterile and parthenocarpic which leads to the production of fruit without seeds. The genetic breeding of plantain and Banana through hybridization is limited by the occurrence of sterility in most cultivars resulting in low production or absence of seeds. Studies are needed to better understand the processes involved in both fertility and sterility. Cultivated Musa species are seedless, Seed set after pollination is an indication of fertility of both male and female parents which can be used to develop hybrids of commercial varieties and wild relatives. The main objective of the present research which was investigated at the Teaching and Research Farm of the Rivers State University, Port Harcourt, Nigeria to identify the fertility status of seven (7) USTPX plantain hybrids which includes USTPx/01/01, USTPx/01/02, USTPx/01/03, USTPx/01/05, USTPx/01/06, USTPX/01/07 and KM5 using in-situ method of screening for fertility. Different interspecific crosses were made. Result indicates that seven (7) species were fertile apart from USTPX/01/07 as they produced seeds after such different interspecific crosses. Out of the seven cultivars pollinated, six cultivars produced a total of 1748 seeds as female parents except from USTPx/01/07 which do not produce neither seeds nor pollen grains. Out of 1748 seeds, the highest numbers of seeds (1346 and 379 seeds) were obtained from USTPx/01/02 and USTPx/01/01 with a mean of 134.6 and 37.9 as female parents respectively in which USTPx/01/02 shows significant difference (P>0.05) from the other cultivars. The highest and the least number of seeds (1076, 412 and 2 seeds) were obtained using pollens from USTPx/01/01, USTPx/01/02 and USTPx/01/06 as male parents respectively
Investigating Local Consumption Cultures and the Global Commodity: Ethnography of Local Culture In The Face of the Gobal In Baneh (Published)
The present research attempts to investigate local consumption cultures and the Global Commodity: Ethnography of Local Culture in the face of The Global in Baneh. Theoretically, the present paper in the frame work of consumption culture theories argues that the face of The Global should be understood in association with identity, Global Neo liberal market and collective ideology. In this research fifteen subjects with approach of participated observation were officially interviewed. As the result it can be concluded that local consumption cultures have the most influence on the market ideology and advertisement mechanism therefore, the role of religion and national features is less effective. The Global which includes particular meanings has the ability to get the satisfaction of consumers in various subculture: thus, the commodity has been successful in corresponding with self-embedded meaning and consumer interest. Local culture commence to accept the logic of market rationalization and follow its rules and in different cases, it has the capability to produce and adjust its commodity with harmonized logic. Local- traditional and Global relationships are continuing to survive: Even tough, market-based rational and logical rules are dominant on relationship form which organize local contents. Marketization and commercialization of public and private sector as well as the local people is a growing process that has involved everyone which result in moral reactions and adopting striking identity strategies.
