Diagnostic surveys were conducted during 2015 and 2016 for screening the susceptible mango germplasm. About five hundred mango germplasm were screened against burl throughout the country. It is a typically swelling of the trunk and branches. Significant variation was observed in shape, colour, site of burl formation, surface, side of burl formation, site of gummosis, branching pattern and canopy of burl-affected trees. The incidence of burl in twenty-three mango germplasm in different parts of India and its effect on yield was also observed. Highest incidence was observed in ‘Arka Aruna’, ‘Mahuvas’, ‘Seedling’, ‘Tree 253’, ‘Mehmud Vikarabad’, ‘Hybrid 10’, ‘Khaja Pasand’, ‘Gopalbhog’, ‘Malai’, ‘Seedling’ 68 and ‘Seedling’ 307 germplasm.Information was also collected on the relationship between the growth of the burl and the age of the trees in ‘Langra’, ‘Bathua’, ‘Sukul’, Banganpalli, ‘Mehmud Vikarabad’, ‘Khaja Pasand’ and ‘Rajapuri’ germplasm. The size of the burl coincides with age of the trees from 25 to 90 years. Orchards topography also play major role in disease incidence and intensity. Maximum fruit yield, minimum disease incidence and intensity recorded in bottom land. Maximum incompatibility, incidence percentage and disease severity were observed in grafted trees while no incidence was observed in non-grafted/’Seedling’ trees reported first time. Hence, the source of burl inoculum was scions taken from infected old mother trees for propagation. These findings may have implications in the understanding of this new woody disease in mango trees.

芒果(Mangifera indica L.)种质筛选:对印度植物形态和移植物不相容性及果园地形的影响

在2015年和2016年进行了诊断调查,以筛选易感芒果种质。在全国范围内筛选出约五百种芒果种质以防b毛。这通常是树干和树枝的肿胀。在形状,颜色,毛孔形成部位,表面,毛孔形成侧面,牙龈病发生部位,分支图案和受毛孔感染的树木的冠层中观察到显着变化。还观察到印度不同地区的23种芒果种质中of的发生率及其对产量的影响。在'Arka Aruna','Mahuvas','Seedling','Tree 253','Mehmud Vikarabad','Hybrid 10','Khaja Pasand','Gopalbhog','Malai','Seedling'中观察到最高的发病率68和“幼苗” 307种质。还收集了有关“兰格拉”,“巴特瓦”,“苏库尔”,班甘帕利,“梅穆德·维卡拉巴德”,“卡贾·帕桑德”和“拉贾普里”种质的树长与树龄之间关系的信息。url的大小与树木的年龄从25岁到90岁相吻合。果园的地形也对疾病的发病率和强度起主要作用。在底层土地上记录的最大水果产量,最小病害发生率和强度。在嫁接的树木中观察到最大的不相容性,发生率和疾病严重性,而在首次报道的非嫁接/“苗木”树木中未观察到发生率。因此,毛url接种物的来源是从受感染的老母树上繁殖的接穗。这些发现可能对理解芒果树中这种新的木本病有影响。Banganpalli,“ Mehmud Vikarabad”,“ Khaja Pasand”和“ Rajapuri”种质。url的大小与树木的年龄从25岁到90岁相吻合。果园的地形也对疾病的发病率和强度起主要作用。在底层土地上记录的最大水果产量,最小病害发生率和强度。在嫁接的树木中观察到最大的不相容性,发生率和疾病严重性,而在首次报道的非嫁接/“苗木”树木中未观察到发生率。因此,毛url接种物的来源是从受感染的老母树上繁殖的接穗。这些发现可能对理解芒果树中这种新的木本病有影响。Banganpalli,“ Mehmud Vikarabad”,“ Khaja Pasand”和“ Rajapuri”种质。url的大小与树木的年龄从25岁到90岁相吻合。果园的地形也对疾病的发病率和强度起主要作用。在底层土地上记录的最大水果产量,最小病害发生率和强度。在嫁接的树木中观察到最大的不相容性,发生率和疾病严重性,而在首次报道的非嫁接/“苗木”树木中未观察到发生率。因此,毛url接种物的来源是从受感染的老母树上繁殖的接穗。这些发现可能对理解芒果树中这种新的木本病有影响。果园的地形也对疾病的发病率和强度起主要作用。在底层土地上记录的最大水果产量,最小病害发生率和强度。在嫁接的树木中观察到最大的不相容性,发生率和疾病严重性,而在首次报道的非嫁接/“苗木”树木中未观察到发生率。因此,毛url接种物的来源是从受感染的老母树上繁殖的接穗。这些发现可能对理解芒果树中这种新的木本病有影响。果园的地形也对疾病的发病率和强度起主要作用。在底层土地上记录的最大水果产量,最小病害发生率和强度。在嫁接的树木中观察到最大的不相容性,发生率和疾病严重性,而在首次报道的非嫁接/“苗木”树木中未观察到发生率。因此,毛url接种物的来源是从受感染的老母树上繁殖的接穗。这些发现可能对理解芒果树中这种新的木本病有影响。在嫁接的树木中观察到发病率和疾病严重性,而在首次报告的非嫁接/“苗木”中没有观察到发病率。因此,毛url接种物的来源是从受感染的老母树上繁殖的接穗。这些发现可能对理解芒果树中这种新的木本病有影响。在嫁接的树木中观察到发病率和疾病严重性,而在首次报道的非嫁接/“苗木”中没有观察到发病率。因此,毛url接种物的来源是从受感染的老母树上繁殖的接穗。这些发现可能对理解芒果树中这种新的木本病有影响。
