Genetic Divergence for Seed Related Characters in Selected Germplasm of Safflower (Carthamus tinctorius L.).
Abstract
The set of 150 genotypes along with five checks 'A-1, Bhima, Manjira, JSF-1 and HUS-305' were evaluated in augemented block design with five blocks at the field of Oilseed Research Unit, Dr. PDKV, Akola during rabi 2012-2013. The data were recorded on the characters viz., days to 50% flowering, days to maturity, number of capitula per plant, number of seeds per capitulum, 100 seed weight (g), hull content (g), volume weight (g/100ml), seed yield per plant and oil content (%). The 150 genotypes were grouped into fourteen clusters. The average inter cluster distance is maximum between clusters IX and XII (3635.208), followed by clusters VI and XII (3615.87), clusters VIII and XII (3542.073), clusters I and XII (2924.360), clusters XII and XIII (2892.245). The seed yield per plant, number of capitula per plant, days to maturity, seeds per capitulum,days to 50% flowering, volume weight, oil content contribute significantly towards genetic divergence. The present study projected the importance of GMU-3439, GMU-3482, GMU-3475 as parents for higher heterosis in F1 and potential transgrants in subsequent generations as they have least mean days to 50% flowering, days to maturity, hull content and high mean of GMU-3590, GMU-3490, GMU-3433, A-1 and GMU-3522 for number of capitula per plant, number of seeds per capitula, 100 seed weight, ,volume weight, seed yield per plant and oil content respectively for the further improvement in respect to these seed characters.
