Selection Indices in Indian Mustard [Brassica juncea (L.) Czern & Coss]
The discriminant-function technique was used to construct selection indices in 50 genotypes of Indian mustard (Brassica juncea). Sixty-three selection indices involving seed yield per plant and its five components were constructed using discriminant function technique. In general, the more the numbe...

| description | The discriminant-function technique was used to construct selection indices in 50 genotypes of Indian mustard (Brassica juncea). Sixty-three selection indices involving seed yield per plant and its five components were constructed using discriminant function technique. In general, the more the number of characters included in a selection index, the better was its performance. The index based on six characters viz., seed yield per plant, biological yield per plant, harvest index, number of primary branches per plant, number of secondary branches per plant and number of siliquae per plant which had a genetic advance and relative efficiency of 122.10g and 1847.80% followed by and index based on five characters seed yield per plant, biological yield per plant, number of primary branches per plant, number of secondary branches per plant and number of siliquae per plant which possessed genetic gain and relative efficiency of 121.94g and 1845.33%, respectively. The use of both these indices is advocated for selecting high yielding genotypes of mustard. |
