Development and Application of Cotton InDel Markers Based on High Throughput Sequencing

[Objective] Dimorphic InDel markers can be used for cotton variety identification and purity detection, to improve the accuracy and efficiency of cotton seed testing, and to play a role in molecular breeding of cotton. [Method] Based on the whole genome sequencing of 121 cotton varieties from different sources, the InDel markers with high polymorphism were developed according to polymorphism information content(PIC) and were applied in the genetic distance analysis and cluster analysis by using 66 cotton varieties in China. [Result] Totally 10 967 InDel were identified based on the next generation sequencing data of 121 cotton varieties. Among the 85 pairs of InDel primers synthesized, 64 were selected including 35 from At group and 29 from Dt group. The minimum average allelic frequency(MAF) of At and Dt chromosomes were 0.45 and 0.32, respectively, while the PIC were 0.49 and 0.40, respectively. The genetic distances of the 66 cotton varieties ranged from 0.04 to 0.65 centimorgan (cM), with an average of 0.39 cM. The two varieties with the largest genetic distance were Simian 3 and CCRI 36, and the two varieties with the smallest genetic distance were Xumian 18 and Xuza 3. [Conclusion] The 64 cotton dimorphic InDel markers can effectively reveal the relationships among varieties based on the genetic distance, and distinguish cotton varieties from different sources, which has certain theoretical significance and application value.

基于新型城镇化背景的耕地利用与保护研究

建国以来，中国城镇化发展经历了六个阶段，呈现出波状起伏、落后于世界水平、依靠政府推动、区域不平衡等特点。城镇化进程中土地利用存在“寅吃卯粮”、农村土地收益流向城镇、土地资源过度开发、耕地健康水平下降、土地政策基本取向难以实现等问题。新型城镇化背景下耕地保护必须有新思维：降低土地消耗强度，提高土地利用效益；建立与农业适度规模经营相适应的农地流转新机制；实施耕地健康养护工程，保障安全食品供给；制定涉地指标省域内跨市有偿调剂和“地随人走”的政策。
