Abstract:
The selection efficiency for certain traits in crops can be broadened using estimates of genetic parameters, which are fundamental for plant breeding. This experiment was conducted in Cereal Crop Research Institute, Nowshera during the summer cropping season 2021-2022. The experimental material consisted of seven popcorn genotypes which were planted in randomized complete block design (RCBD) with three replications. Data on days to 50% pollen shedding, days to 50% silking, plant height, plant population ha-1, ears height, ears ha1 and grain yield tones ha-1 was recorded. Analysis of variance indicated significant differences for all the traits under study. Significant differences among popcorn genotypes provided justification for genetic analysis. Among the genotypes of popcorn, G-7 indicated best mean performance for days to 50% pollen shedding, days to 50% siking and plant height while genotype, G-1 revealed best mean performance for grain yield hectare-1, plant population hectare-1 and ear population hectare-1. In ear height lower ear placement on the stalk is desirable because it is less susceptible to lodging as strong winds at or near maturity can cause severe lodging and substantial yield loss. The genotype, G-5 was recorded for lower ear height (74.86 cm). Heritability estimation revealed maximum heritability (99.78%) for plant height while plant population ha-1 showed low heritability (2.87%). Maximum genetic advance was revealed for plant height (4. 89 cm) Therefore it is concluded that the genotype, G-7 is early maturing and was short stature, therefore it could be used in future breeding program as gene source for further improvement.
