The consequences of self-fertilization are important factors determining the germplasm management in such species with levels of heterogeneity and heterozygsity. Effects of self-fertilization on floral, yield and yield components characters were evaluated by comparing two levels of selfing, produced in bee-proof cages, in open-pollination at two locations in Sudan. Selfing process results in no significant differences in yield and yield components within each cultivar. Autofertile lines with reduced partial dependence on insects for seed set could be produced. Spatial isolation should be used to maintain the genetic purity of such lines. An alternate strategy for entries multiplication should focus on increasing heterozygosity and the maintenance of cross-fertilization inside the entries to prevent contamination with foreign pollens. Our results follow the previous knowledge on faba bean genetic resources conservation and management.展开更多

Although the government has introduced a series of supportive policies, but small and micro enterprises arc still faced with many development problems, small and micro enterprises face an important problem is financing difficulty, which relates to its health, sustainable and stable development. This paper analyzes the financing problem of small and micro enterprises from the new net loan mode of P2B, hoping to benefit the development of small and micro enterprises.展开更多
