海陆杂种棉研究现状及发展趋势

Research situation and develop tendency of sea-island and land hybrid cotton

海陆杂种棉在生物学性状上表现诸多优势 ,比如结铃性优势 ,纤维品质性状表达优势 ,光合作用效率优势以及抗旱、耐瘠、抗病虫等抗逆性优势 ;但也存在不孕籽多、铃小、较晚熟等突出问题。克服存在的缺陷 ,发挥其独特的杂合优势 ,将为海陆杂种棉的开发利用提供巨大的发展潜力。

Sea-island and land hybrid express lots of vigor in biological character.Such as the vigor of boll-forming,vigor of fibre quality character express.Vigor of photosynthesis effectiveness and the vigor of adverse resistance.But it has some problem such as the boll is small and late-matured ete.We should surmount the defect and ultilize hybrid vigor.
