Abstract:
The present investigation entitled “Study of phenotypic characters and diversity assessment of primary genotypes of mango (Mangifera indica L.) in Bihar” was carried out in the Department of Horticulture (Fruit & Fruit Technology), Bihar Agricultural College, Sabour, Bhagalpur, Bihar. Twenty five mango genotypes were studied for their leaf characteristics and flowering behavior. Wide variability was recorded among various phenotypic traits of Leaf apex shape was varied from acuminate to acute shape, Leaf base shape of mango genotypes was obtuse to acute shape found in most of the genotypes. Young leaf colour of mango genotypes was observed light green colour, deep coppery tan colour, light brick red colour and light green with brownish tinge colour in the almost genotypes. Fully developed leaf colour of mango genotypes was found to be dark green colour in all the mango genotypes. Leaf blade shape of mango genotypes was observed ovate to lanceolate in most of the genotypes. So it could be used as one of the parent in mango breeding programme for enhancing photosynthetase accumulation and enhancing the yield per plant. This study may also be useful for examine the leaf shape, leaf colour and leaf margin to observe morphological variation in mango genotypes.
