Abstract:

An investigation was taken up at Maize Research Station, Agricultural Research Institute, PJTSAU, Hyderabad during 2013-14. F1 material was generated by making crosses between BML 6 × CML 181 and BML 7 × CML 181for introgression of opaque 2 gene from Mexican donor CML181 through molecular breeding approach. The converted quality protein maize BML 6 and BML 7 lines (designated as CB6 and CB7) with increased levels of lysine and tryptophan were crossed in various combinations to select a hybrid with increased lysine, tryptophan and high yield. The performance of elite maize genotypes, donor and derived QPM inbreds and their hybrid combinations were analysed for yield and yield attributing characters. The experiment was designed with three replication following Randomized Block Design. Observations were recorded on twelve quantitative and qualitative traits. Hybrids recorded superior performance to parents with respect to plant height (cm), ear height (cm), number of kernel rows per ear, 100 kernel weights (g), grain yield per plant (g) and tryptophan content (%). Two cross combinations CB6-36 × CB7-28 and CB6-36 × CB7-59 exhibited relatively higher tryptophan content and on par grain yield per plant compared to the standard check DHM 117. The hybrid combination CB6-36 × CB7-28 was shown excellent performance at All Indian Coordinate Research Project (AICRP) on Maize trails during the year 2015-16 and the yield was 6924 Kg/ha (BQPMH141) with higher tryptophan content and these hybrid parental lines need to be further multiplied for commercial exploitation.


Keywords: Performance, Yield and tryptophan content.
