提高烟叶品质,是当前烤烟育种的主攻方向。但因烟叶品质问题复杂,影响因子较多,所以品质育种难度较大。本文从育种需要出发,对烤烟的几个经济性状进行初步分析,目的是了解和掌握影响烟叶品质的性状之间的相关性;探讨优质丰产品种的主要性状结构,以期提高选择的准确性和预见性,减少盲目性。材料和方法分析资料来自本所1979年鉴定圃。供试材料29份,其中品种6个,品系21个,雄性不育一代杂交种2个(表1)。田间设计为随机排列,重复三次,双行区,行长13米,行距3市尺、株距1.3市尺(合每亩1538株),小区株数为60株。田间管理同一般试验田。
Improve the quality of tobacco is the main direction of the current breeding of tobacco. However, because of the complicated quality problems of tobacco leaves and many influencing factors, quality breeding is more difficult. Based on the need of breeding, this paper conducted a preliminary analysis on several economic traits of flue-cured tobacco in order to understand and grasp the correlation between the traits that affect the quality of tobacco leaves and to explore the main traits of high-yielding varieties to improve the accuracy of selection and Predictability, reduce blindness. Material and method analysis data from the 1979 identification garden. 29 materials were tested, including 6 varieties, 21 lines and 2 male sterile hybrids (Table 1). Field design for the random arrangement, repeated three times, double row area, governor 13 meters, spacing 3 feet, spacing of 1.3 feet (mu of 1538 per acre), cell number of 60. Field management with the general test field.
