Evaluation on reproductive and productivity characters of wheat (Triticum aestivum L.) genotypes grown in the lowlands

Abstract

The objective of this study is to obtain mutant and convergent wheat breeding lines adapted to lowlands with high productivity and high heritability characters. This research was carried out in Bonto Parang, Tolo Selatan Village, Kelara District, Jeneponto Regency with coordinates 5 24′58.0″S 119 54′58.2″E at 135 m above sea level (asl). This research took place from May to September 2019. This study was arranged with Randomized Complete Block Design with 20 genotypes and 4 control varieties (Dewata, Guri-3, Selayar, and Nias). The study was conducted with 3 replications so that there were 72 experimental units. The results show that adaptive mutant lines and convergent wheat breeding in lowlands with high productivity were shown by genotype N 250 4.6.2 (2.27 t ha-1), S 300 7.9.1 (2.29 t ha-1), S 300 8.3. 1 (2.35 t ha-1), N 200 2.5.2 (2.27 t ha-1), S 300 2.1 (2.29 t ha-1), CBF6-110 (2, 31 t ha-1), and CBF6-192 (2.37 t ha-1). Characters that have high heritability values were panicle length, the number of spikelets per panicle, seed weight per panicle, the potential yield per plant, and productivity.
