Subscribe/Renew Journal
The present study on diallel graphical analysis was conducted at Department of Horticulture, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai during 2016 according to hayman on growth, yield and quality traits of pumpkin. Six advanced pumpkin genotypes viz., P1: Acc.No. MDU CM23-Thirumangalam local, Madurai district, P2: Acc.No. MDU CM28-Oddanchatram local, Dinddugul district, P3: Acc.No. MDU CM29-Harur local, Dharmapuri district, P4: Acc.No. MDU CM12-Department of Horticulture, AC and RI Madurai, P5: Acc.No. MDU CM1-Attur local, Salem district, P6: Acc.No. MDU CM31-Rajapalayam local, Virudhunagar district was used to investigate the genetic control of the growth, yield and quality traits are dominance or over dominance and in each the genotypes whether the traits are controlled by dominant or recessive alleles. All the six parents and their 30 F1 hybrids were raised in the field in Randomized Block Design with two replications. The various growth, yield and quality traits viz., vine length, number of primary branches, days to first male flower, days to first female flower, node to first male flower, node to first female flower, sex ratio, days to first harvest, number of fruits per vine, average fruit weight, fruit length, fruit diameter, yield per plant, flesh thickness, number of seeds per fruit, total soluble solids, beta carotene and dry matter content of fruits were recorded. The data were subject to Hayman’s genetic analysis to investigate nature of expression and their alleles on the growth, yield and quality traits. The study showed that dominance alleles were present in P4 parent for vine length, sex ratio, number of fruits per plant, fruit yield per vine and beta carotene content. This parent also possessed recessive genes for traits such as, number of primary branches and days to first female flower. The parents P1 and P2 possessed recessive alleles for vine length, number of primary branches, number of fruits per plant and beta carotene and these parents also inherit dominant and recessive alleles for the traits, days to first female flower, sex ratio and fruit weight.
