从春小麦优良品种“东农120”的育成中证明,选育出综合性状优良的小麦品种是完全可能的。“东农120”不仅抗多种病害,而且高产又质佳。它的育成是在正确育种目标指导下,采用复合杂交,以逐步达到综合多方面的优良性状;并对杂种后代的选择是在促进选择性状易于表现和鉴别的条件下,根据各性状遗传性稳定的早晚按世代分先后;根据育种目标的主次分前后,采取选择性状由少到多,逐步达到全面综合选择的方式。说明这些措施对选育出综合性状优良的品种是十分有效的。
From the breeding of “Dongnong 120”, an excellent spring wheat variety, it was proved that it is possible to breed wheat varieties with good comprehensive characters. “Dongnong 120” is not only resistant to a variety of diseases, but also high yield and good quality. It is bred under the guidance of the correct breeding objectives, the use of hybrid cross, in order to gradually achieve a comprehensive multi-faceted traits; and the selection of hybrid offspring is to promote the selection of traits and easy identification and performance of the conditions, according to the genetic stability of traits Sooner or later, according to generations; according to breeding objectives before and after the primary and secondary points to take to choose less to many traits, and gradually achieve a comprehensive and comprehensive choice of ways. This shows that these measures are very effective for breed breeding varieties with good characters.

内容摘要：《文心雕龙》五十篇在“纲领”和“毛目”的理论系统下展开，呈现出严谨缜密的思理逻辑。刘勰在文体论部分运用象喻批评论述了文体渊源、文学创作、文学批评、作家才能等一系列问题，正体现了这一逻辑建构特征，由此成为我国古代文学理论史上一部辞理兼赡的批评佳作。 关键词：《文心雕龙》 象喻批评逻辑建构 在“论文叙笔”部分，《序志》篇曰：“若乃论文叙笔，则囿别区分，原始以表末，释名以章义，选文以定篇，
