ABSTRACT
The Eight genetically diverse open pollinated populations were crossed in all possible combination (excluding reciprocals) during Rabi season of 2013-2014 in a varietal diallel fashion. The resultant 28 F1 progenies along with eight parents were evaluated in RBD with four environments with 3 replications during, Rabi 2014-15 at the Agricultural Research Farm of S.K.N. College of Agriculture, Jobner.
In the present investigation, highly heterotic crosses RTM-1351 x RTM-314, RTM-314 x RTM-1359, RTM-1415 X RTM-2002 and T-27 x RTM-2002 in all the four environments, were desirable as they had high seed yield per plant, with high heterobeltiosis not only for seed yield per plant but for some than the other yield traits studied. For seed yield per plant, cross T-27 x RTM-2002 and RTM-1415 x RTM-2002 showed significant with high positive heterobeltiosis in all the four environments, while, cross RTM-1375 x RTM-1212 showed significant with high positive heterobeltiosis in environments- I, cross RTM-2002 x RTM-1359 showed significant with high positive heterobeltiosis in environment II, cross T-27 x RTM-1351 showed significant with high positive heterobeltiosis in environment III, cross RTM-1415 x RTM-2002 showed significant with high positive heterobeltiosis in environment IV. For oil content, cross T-27 x RTM-1351 and RTM-1212 x RTM-2002 showed significant with high positive heterobeltiosis in environment-I, while, cross RTM-1351 x RTM-2002 showed significant with high positive heterobeltiosis in environments-II, cross RTM-2002 x RTM-314 and cross T-27 x RTM-2002 showed significant with high positive heterobeltiosis in environment III, cross T-27 x RTM-1212 and cross RTM-1212 x RTM-2002 showed significant with high positive heterobeltiosis in environment IV.Development of inbreds is at present is not feasible because of sporophytic self-incompatibility. Parents RTM-1375, RTM-1415, RTM-314, T-27 and RTM-1359 can be used in population improvement to develop high yielding synthetic varieties having high seed yield and oil content.
