The experimental material comprised of five lines viz., ANDCP 06-07, ANDCP 08-01, SKP 84, SP 1 and VP 1 as well asninetesters namely RG 2275, SI 1, SI 2, ANDCI 8, SI 5, SI 7, SI 10, JI 398 and JI 401 alongwith their 45 hybrids derived from line x tester mating design. The 60 genotypes including check hybrid, GCH 7 were evaluated in a Randomized Block Design with three replications under four artificially created environments using two sowing dates in two years. The observations on five randomly selected plants were recorded for 13 characters viz., seed yield per plant, days to flowering of primary raceme, number of nodes upto primary raceme, plant height upto primary raceme, days to maturity of primary raceme, effective length of primary raceme, number of capsules on primary raceme, number of effective branches per plant, total number of branches per plant, shelling out-turn, 100-seed weight, Volume weight and oil content.en-USnullThesis
