【摘要】 川蔗91／91是我所拟订杂交组合（CP57／614×川蔗10号），委托中国轻工总会甘蔗糖业研究所海南甘蔗育种场杂交，在盆地内培育实生苗，在攀西米易蔗区选育而成的甘蔗新品系。其突出特点是集高产稳产高糖于一身的中大茎、中早熟品种。经多年多点（次）试验表明：川糖91／91在米易蔗区比主栽品种川蔗13号增产12．5％，增糖14．8％。抗旱试验表明：田间受旱期间川糖91／91株高生长快于对照，盆栽抗旱试验相关生理指标优于对照，表现出较强的抗旱性。因此，该品系在米易蔗区及其干旱条件相似的攀西其它蔗区繁殖推广可望发挥较大的增产增糖潜力。更多还原

【Abstract】 Which crossed by Hainan Sugarcane Breeding Station, CT91/91 what cultured seeding in inland cane areas was selected from CP57/614 × CZ10 in Miyi county. It is a high and stable-yield, high sucrose content, mid-big diameter and early-midle mature variety. Multilocation (time) trials indicated CT91/91 was 12. 5% higher cane-yield, 14. 8% higher sugar-yield than CZ13 in several years. Drought-resistant trials showed the plant hieght of CT91/91 was higher in arid fields and relative physiological indexes were more excellent in drought test of pot planting than checked varieties. So, CT91/91 can be extended in Miyi and other cane-growing areas with alike at climatic conditions in Panxi because of sugar and cane-yielding potential ittes.更多还原
