“…This was identified in the selected inbred cross combinations, which also showed desirable SCA for FEW and SEW. Similar findings were reported by Choudhary, Marker, Battacharjee, & Ramnath (2018), El-Badawy (2013 and Rani, Nirala, & Acharya (2018). The genetic patterns of inbred crosses that showed good SCA were established.…”

Testing an inbred cross for hybrid development requires a proper test cross method. The diallel is one crossing method to find out the magnitude of inbred combining ability, both general general (GCA) and specific combining ability (SCA) and specific combining ability, that is useful in hybrid development. The objective of the study is to determine the GCA, SCA and heterosis of 6 inbred lines in two seasons. All the inbreds were crossed in diallel design and further evaluated for their combining ability and genetic ratio following the respective methods of Griffing and Baker. The results revealed that GCA, SCA and Reciprocal (REC.) were influenced by planting seasons for almost all yield and yield-related traits. Non-additive gene action was more important in controlling ear length, ear row number, shelled ear weight and yield. The best GCA for yield trait was detected on inbreds G2 and G5. The conclusion from the interpretation of both SCA and REC. is that the inbred crosses of G1 x G6, G2 x G5, G4 x G6, and G5 x G6 have the best yields followed by high heterosis values.

“…Positive means that the crosses (hybrids) are better than the negative ones (even have the same traits). A negative value means that the crosses (hybrids), which have the same traits, are inadequate compared to the positive ones (Bucheyeki et al, 2017;Choudhary et al, 2018;Khan et al, 2020).…”

“…In contrast, the specific combining ability (SCA) plays a role in determining the best crosses on maize hybrid development. The identified populations with excellent General Combining Ability may have a chance to produce high specific combining ability (Choudhary et al, 2018;Murtadha et al, 2018).…”

Maize is a cereal crop essential to fulfill the need for food and support global food security programs. Maize hybrid varieties play a very significant role in increasing maize production. Objectives of the research were to obtain a tester, which is consistent in identifying inbred lines with a high specific combining ability, and to obtain prospective crossed-hybrids that have the potential assembling to be maize hybrid varieties. The grain yield showed that the specific combining ability values ranged from -3682.2 to 5251.7. Crosses that have high and positive specific combining ability included lines of JG-11, JG-18, JG-34, JG-01, JG-40, JG-B0, JG-19, and JG-02 with a tester of JG-T00; lines of JG-20, JG-01, JG-03, JG-42, JG-02, JG-46, and tester of JG-T14; lines of JG-24, JG-08, JG-23, JG-26, JG-21, JG-07, and JG-06 with a tester of JG-T15; lines of JG-38, JG-40, JG-35, JG-36, JG-01, JG-51, JG-17, JG-B0, and JG-08 with tester of JG-T22; and lines of JG-07, JG-01, JG-26, JG-24, and JG-18 with tester of JG-T37. There were combinations of 9 crosses between inbred lines and the best testers, including JG-06XJG-T15, JG-51XJG-T22, JG-49XJG-T22, JG-B0XJG-T22, JG-35XJG-T22, JG-38XJG-T22, JG-17XJG-T22, JG-36XJG-T22, and JG-49XJG-37, which are potential as prospective maize hybrids that have high productivity.
