dc.description.abstractAn investigation entitled, “Standardization of pruning time and molecular characterization in guava (Psidium guajava L.) genotypes” was undertaken with an objective to study the growth, yield and quality of guava and molecular characterization of guava genotypes. The experiment was conducted during the year 2016 and 2017 at the Instructionalcum- Research Farm, Department of Horticulture and State Level Biotechnology Center, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar. The present investigations were conducted on seven different genotypes namely RHRGuv- 58, RHR-Guv-60, RHR-Guv-14, RHR-Guv-16, RHR-Guv-3, RHR-Guv-6 and Sardar with five pruning time i.e. 15th May, 15th June, 15th July, 15th August, 15th Sept. and no pruning (control). The genotypes were pruned at different times to understand influence on growth and yield as well as infestation of fruit fly, a major pest of guava. In order to minimize the infestation of fruit fly an additional treatment bagging of fruits was undertaken. The experiment was laid out in Factorial Randomized Block Design with forty two treatments and was replicated two times. Observations on growth attributes, yield parameters as well as quality attributes were recorded. Seven genotypes were subjected to molecular characterization using ISSR markers. Different pruning times and genotypes were recorded significant differences on growth characters. The growth attributes results revealed that the significantly maximum plant height (2.42 m), plant spread EW (5.86 m) and NS (5.74 m), sprouted shoots (140.29), shoot length (82.17 cm) and girth (1.86 cm) was recorded in Sardar. The significantly minimum time required for initiation of new shoots (24.00 days) was observed in Sardar with 15th May pruning time.en_US
