【摘要】 河洛1号是以G80为母本、CV87为父本，聚焦耐旱兼顾抗性与品质等育种目标，通过系谱法连续选择培育出的烤烟新品种。该品种田间长势强，茎秆粗壮；中抗赤星病，中感PVY，感青枯病、黑胫病、根结线虫病、TMV和CMV；耐旱性好，成熟期叶片分层落黄明显，耐成熟，易烘烤；烤后烟叶颜色多金黄，结构疏松至尚疏松，身份中等，油分稍有至有，色度中至强，整体外观质量优于主对照NC89；该品种产量、产值等主要经济性状高于对照品种NC89；原烟各化学成分含量均在适宜范围之内，协调性较好，略优于对照，感官质量优于主对照NC89，与副对照中烟100基本相当。综上所述，河洛1号是一个耐旱性突出的优良品种，适宜在我国黄淮烟区和东北烟区种植。更多还原

【Abstract】 Heluo1 is a new flue-cured tobacco variety developed through pedigree selection, with G80 as the female parent and CV87 as the male parent. Its breeding focused on drought tolerance, disease resistance, and quality. The variety exhibits vigorous field growth with thick and sturdy stalks. It shows moderate resistance to brown spot, moderate susceptibility to PVY, and susceptibility to bacterial wilt, black shank, root-knot nematode, TMV, and CMV. It demonstrates good drought tolerance, with leaves showing distinct layered yellowing at maturity, good maturation tolerance, and easy curability. The cured leaves are predominantly golden-colored with a loose to fairly loose structure, medium body, slight to moderate oil content, and medium to strong color intensity. Its overall appearance quality is better than that of the main control variety NC89. The main economic traits such as yield and output value of this variety are higher than those of NC89. The content of each chemical component in the raw tobacco is within the appropriate range, with good coordination, slightly superior to the control. Its sensory quality is better than NC89 and comparable to the secondary control, Zhongyan100. In summary, Heluo1 is an excellent variety with outstanding drought tolerance, suitable for cultivation in the Huanghuai and Northeastern tobacco-growing regions of China.更多还原
