Abstract
ABSTRACT
The present study titled, “Evaluation of selected peach (Prunus persica L. Batsch)
cultivars” was carried out during 2018-2019 at the Model farm, Directorate of Research, Dr. YS
Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Seven peach cultivars viz.
‘Andros’, ‘Glohaven’, ‘Paradelux’, ‘Pratap’, ‘Redhaven’, ‘Shan-i-Punjab’ and ‘Suncrest’ was
evaluated for their tree, foliage, floral and fruit characteristics and to studythe variability, heritability,
correlation and path analysis of different characters. Wide range of variability was observed among
all the cultivars for different plant characters. On the basis of overall mean performance, the cultivar
‘Pratap’ has been found promising for better fruit quality followed by cultivar ‘Shan-i-Punjab’.
However, regarding yield characteristics cultivar ‘Redhaven’ was found best. High heritability
coupled with high genetic gain was observed for characters like tree volume, trunk girth, fruit weight,
fruit volume, pulp weight, pulp/stone ratio and yield. While, high heritability coupled with moderate
genetic gain was obtained for characters like tree height, fruit length, fruit length/diameter ratio,
specific gravity, total soluble solids, reducing sugars and stone weight, indicating predominance of
additive gene action in the inheritance of these characters, hence selection would be effective for
genetic improvement of said characters in desired direction. The correlation studyrevealed significant
and positive correlation of yield with leaf blade width and titratable acidity at phenotypic and
genotypic level, respectively. Highest direct positive effects toward yield was contributed by fruit
length, fruit weight, fruit set, total sugars, total soluble solids, tree volume, leaf blade length,
pulp/stone ratio, leaf blade width and fruit firmness, hence could be given due weightage during
selection process for yield improvement of selected peach cultivars.
