Partial DNA-A sequence comparison with other geminiviruses showed that G7 were infected with 5 begomoviruses, these viruses were Papaya leaf curl China virus, Ageratum yellow vein china virus, Tomato leaf curl China virus, Euphorbia leaf curl virus and Tobacco leaf curl Yunnan virus.

得到部分G7的DNA一A序列，经NCBI检索和序列比较分析发现了5种菜豆金色叶病毒属病毒的部分DNA序列，分别是中国番木瓜曲叶病毒、中国胜红蓟黄脉病毒、中国番茄曲叶病毒、一品红曲叶病毒、云南烟草曲叶病毒。

The main results were showed as follows:Through screen and identification of morphology in M_2 and M_3, respectively, the mutants with mutative traits of plant were found. In which, 11 mutations were leaf variations, including light-green leaf, deep-green leaf, durative yellowish leaf, temporary yellowish leaf, inlaid yellowish leaf, wrinkly leaf, smooth-edged curly leaf, splitting-shaped curly leaf, peduncular-shaped leaf, round leaf and larger leaf, 12 were mutations on plant type, including excessive branches, lacking branches, highness, dwarf-like, erect posture, reclinate posture, strong stalk, slender stalk, tufty branches, wrinkled plant, purple stalk and hair-covered plant, 14 were flower variations, including dense flowers, light-yellow petals, white petals, white-mosaic petals, wrinkled petales, back-rolled petals, narrow petals, larger petals, smaller petals, apetalous flowers, variable-numbered petals, fertile pistil protraction, sterile pistil protraction and multi-anther, and 5 were physiologic mutants, including genic male sterile, cytoplasmic male sterile, bud-dead, and early and later bloom.

主要结果如下：通过田间M_2筛选和M_3重复鉴定，在田间农艺性状方面共获得浅绿叶色、深绿叶色、转绿黄化叶、持续黄化叶、边缘黄化叶、皱缩叶、光叶型卷叶、裂叶型卷叶、薹叶形叶、宽圆叶和大叶等11种不同的叶部性状突变体；同时还筛选到多分枝、少分枝、高杆、矮杆、株型紧凑、株型松散、粗茎、细茎、丛生分枝、整株皱缩、紫茎、整株被毛等12种植株性状突变体，密花、浅色花瓣、白色花瓣、白斑花瓣、皱瓣、卷瓣、窄瓣、大瓣、小瓣、无瓣、花瓣数目不定、可育型柱头外露、不育型柱头外露和多雄蕊等14种花器性状突变体，以及细胞核雄性不育、细胞质雄性不育、死蕾、早花和迟花等5种生理性状突变体。

The canopy structure and leaf morphological characters of 4 sugarcane genotypes at different leaf layers on seedling were studied by using CI-100 plant canopy instrument and CI-203 area meter instrument. The results showed the leaf morphological parameters, canopy structure and radiation transmission at different leaf layers were notably different among different genotypes. The variation of Ila, Amfi, Dl at different leaf layers were mainly caused by the leaf width at relevant position. The variation of K at different leaf layers was related to Amfi and Dl. The variation of Td（transm. coef. for diffuse penetration）had significant correlations with Ila, Amfi and Dl. The variation of Tr（transm. coef. for radiation penetration）had significant correlations with Dl, leaf width and the ratio of leaf length to width. The variation of Par had significant correlations with Ila, leaf area, leaf width and the ratio of leaf length to width.

摘要利用CI-100数字植物冠层分析仪和CI-203叶面积分析仪测定了4个甘蔗品种不同叶位层的冠层参数和相应叶位叶片的形态特征，结果表明：不同基因型不同叶位层间叶片形态、冠层空间结构和冠层辐射特征存在显著差异，不同叶位层叶面积指数、叶簇倾角和叶分布的变化主要由冠层内不同叶位叶片叶宽的变化引起，而不同叶位层消光系数的变化主要与叶簇倾角和叶分布有关；散射光透过系数的变化主要与叶面积指数、叶簇倾角和叶分布有关，直射光透过系数的变化主要与叶分布、叶宽、长宽比有关，光合有效辐射的变化与叶面积指数、叶面积、叶宽、长宽比有关。
