Identify Promising Parents and Crosses of Taramira (Eruca sativa Mill.) for Improvement in Irrigated and Drought Conditions

Abstract

The parents (varieties) RTM-1359 and RTM-1375 superior in all the environments, RTM-314 in the environment-II and III were found to be superior based on vi effects and per se performance not only for seed yield per plant but for some of the other yield traits studied. The parents worth considered on the basis of hi values were RTM-1375 in environment-I, RTM-314 in environment-II, while RTM-1415 and RTM-1359 in the environment-III and RTM-314, RTM-1359 in environment-IV. It was therefore recommended to include these parents in hybridization programme to improve seed yield and seed quality. Highly heterotic crosses RTM-1351 x RTM-314, RTM-314 x RTM-1359, RTM-1415 X RTM-2002 and T-27 x RTM-2002 superior in all the four environments, were desirable as they had high seed yield per plant, high sii’ values, with high heterobeltiosis and economic heterosis not only for seed yield per plant but for some than the other yield traits studied.
