摘要
海岛棉品种区域试验是进行生产试验和新品种审定的基础。为了克服传统品种评价的局限性,增强海岛棉新品种在筛选、推广、示范、利用方面的竞争力,为制定育种目标,挖掘高产优质潜力提供科学依据。采用同异分析法,对27个海岛棉品种(系)的14个性状进行综合分析,从中筛选出综合性状较好的品种。‘H3549’的综合同一度最大,表明该品种综合性状表现最好,14个性状中有96.79%的性状达到了育种目标的要求,其次为‘33687’,这2个品种产量与其品质性状都具有相对优势,综合性状较好,为优先考虑推广品种。‘K-379’、‘X-2038’、‘H5161’、‘TH-314’、‘DJ10149’、‘G-92’、‘JSH12-3’、‘元龙10号’、‘塔09-164’等品种(系)的伸长率、比强度、产量、株铃数低,马克隆值略高,并提出今后改良的方向。‘DJ09-172’、‘长丰2号’、‘塔08-362’、‘塔09-324’、‘塔10-280’、‘11-616’6个品种(系)与理想品种的联系度较低,需进一步试验观察或给予淘汰。同异分析方法运算简便,易于掌握,在海岛棉新品种(系)区域试验中应用切实可行。
Regional Test is the basis for production test and new variety registration. To overcome the limitation of traditional cultivar evaluation and enhance the competitiveness of new cultivar Gossypium barbadense L. on screening, promotion, demonstration and utilization can provide a scientific basis for setting variety breeding goals and mining high yield potential. Identical and different analysis method was used for comprehensive evaluation of 14 traits in 27 Gossypium barbadense L. cultivars（lines）, and cultivars with good comprehensive trait were selected.‘H3549’ had the highest comprehensive identical degree, which indicated that ‘H3549’ had the best comprehensive traits, 96.79% of its 14 traits reached the breeding goals. The second was ‘33687’ .The yield and quality traits of the above two cultivars had relative advantage, the comprehensive traits werebetter, so the two could be preferentially popularized cultivars. Elongation rate, tenacity, yield and boll numberper plant of ‘K-379’,‘ X-2038’,‘H5161’,‘TH-314’,‘DJ10149’,‘G-92’,‘JSH12-3’,‘Yuanlong-10’ and ‘Tarim09- 164’ were lower, micronaire value were higher, and improvement approaches had been proposed. Connection degree of‘DJ09-172’,‘Changfeng-2’,‘Tarim08-362’,‘Tarim09-324’,‘Tarim10-280’ and‘11-616’ were low with ideal cultivars, and need further observation or to be eliminated. Identical and different analysis method is simple in calculation and easy to master, feasible in regional test of Gossypium barbadense L..
