Determination of the yield and quality of some experimental hybrid dent corn (Zea mays var. indentata Sturt.) in Bursa conditions

There search was carried out in the Bursa location in 2019-2021, six pure mainstream (Line) and three pure dad testing (tester) linesaccordingtothemulti-array (Line x tester) method. The combination of 18 hybrids and 9 Mothers were carried out in 3 ramers according to the trial pattern. In the study, the number of blooming days (days), plantlength (cm), coachheight (cm), coach-length (cm) cob diameter, the number of rows in the ranking number, the number of ranks in the ranking number, the number of ranks, the number of ranksand the number of coaching, hectoliter weight (g / l), the percentage of the percentage (%), such as decendar grain yield per decare (kg) has beenexamined. As a result of the detected analysis of variance, genotypes and crosses to parents were found to be important in all traits, but blocks, parents, lines, testers, line x tester interaction were also determined to be important in some traits. The effects of special adaptability were significant in features such as ear height, number of grains per ear, grain yield, number of flowering days and 1000 grain weight. Considering the general combination ability, it can be recommended to use NC272, FRMo17, FR 73, S16033 and BRS316 varieties as rootstocks in breeding programs. GUY/PL variance was found to be less than 1 in all the traits examined, except for the number of days to bloom. It has been concluded that non-additive gene effects or dominant gene effects are effective on these examined features. Considering the heterosis - heterobeltiosis values, the lowest values of %-45.6 and %-15.4 were obtained in the number of rows on the cob, and the highest grain yield was obtained with %177.3 and %144.7, respectively. As a result, BRS316 x S16022, NC272 x Ç2002S22, NC272 x S16022, BRS316 x Ç2002S22, FR73 x Ç2002S22 and S16033 x S16022 were promising hybrid combinations in terms of grain yield. Considering the NC272 and S16022 lines, which have positive effects on the general adaptability, in crossing studies will provide an advantage to the researcher.
