Performance of Test Crosses of Maize Variety Sarhad White with Jalal and Kiramat for Morphological Traits

This research was carried out at Khyber Pakhtunkhwa Agricultural University Peshawar to evaluate the performance of maize inbred lines derived from maize variety Sarhad White regarding grain yield and morphological traits and identifying superior inbred lines based on test cross performance. Test crosses were evaluated in replicated trial along with two tester, one check and 16 parental inbred lines for comparison in a 7×7 partially balanced lattice square design with two replications. Results revealed highly significant differences among the genotypes for most of the traits. Jalal TC-230-a and TC-63-1 took the maximum days to tasseling and Jalal TC-101-2 showed maximum days to anthesis. Maximum day to silking and anthesis silking interval were recorded in Jalal TC-94. Maximum plant height was observed in Jalal TC-33 (164.5 cm) and Kiramat TC-9-6-1 (141.50 cm). Maximum 100 kernal weight was recorded in Jalal TC-101-2 (40.55 g). Kiramat TC-89-b produced the highest grain yield (6808 kg ha-1). From these results, it can be concluded that Kiramat TC-89-b, having highest yield, could be promoted for further selfing. Jalal TC-9-6, TC-9-6-1, TC-12-1, TC-63-1, TC-76-2b, TC-89b, TC-163, TC-205, TC-230a, TC-211 and Kiramat TC-9-6, TC-9-6-1, TC-12-1, TC-33, TC-76-2b, TC-89b, TC-94, TC-101-2, 150-c, TC-163, TC-230-a, 205, 211, 226-2 in addition to having satisfactory grain yield could be used for selfing. Among parental lines (selfed lines) 9-6-1, 9-6, 10-2, 226-2, 33, 63-1, 76-2, 163, 89-b, 205 and 211 were promising for grain yield and morphological traits.
