[Method] A total of 111 hybrids were obtained by crossing 37 restorer lines in China and South Asia with Gang 46A, Lu 98A and Dexiang 074 following a NC II design. The combining ability of eight yield traits of the hybrids was analyzed in Luzhou and Deyang bases of Sichuan Province. [Result] In both bases, the eight yield traits had significant or extremely significant differences between the combina- tions, restorer lines, sterile lines or sterile line^restorer line, suggesting that there were d^erences in the genetic effects between the combinations or lines. The gen- eral combining ability （GCA） variances were all higher than special combining ability （SCA） variances in parents, which indicated that these traits were affected by gene additive effect. Restorer lines contributed more to F1 generation than male sterile liens in the eight yield traits. Nine restorer lines from India and Bangladesh were ranked in the top 15 lines with high GCA in the number of productive tillers in both bases. [Co.cl.siee] There was significant differences in the combining ability in the eight yield traits between the restorer lines from China and South Asia. The lines from India and Bangladesh were better than those from China in the GCA of the number of productive tillers, and the lines from China were better than those from India and Bangladesh in the GCA of other traits.展开更多

The research starts by posing the following questions. Can we claim, in a general perspective of improvement of the quality of life in towns and cities, that the recovery of abandoned historic buildings could be a key-factor in conservation and innovation policies of the historical heart of towns？ What relationship, if any, is there between the adaptive-reuse design of ancient hospitals and the effects of such action, not only in terms of heritage conservation but also in terms of economic and social regeneration of the surrounding context？ The complexity of this issue is addressed by analyzing related cases, relevant for their design solutions and effects, and proposes answers to the opening questions by correlating the main characters of relevant case studies in Europe.展开更多
