COMPARATIVE PERFORMANCE OF PROMISING ADVANCED WHEAT GENOTYPES WITH COMMERCIAL WHEAT CULTIVARS IN SINDH

Abstract

An experiment was carried out to evaluate the comparative performance of promising advanced wheat genotypes. Fourteen genotypes with three check varieties viz. Kiran-95, T.J-83 and T.D-1 were evaluated for yield and yield associated traits. Experiment was laid-out in randomized complete block design (RCBD) consisting of three replications during the crop year 2012-2013. The analysis of variance (ANOVA) revealed significant differences between varieties for different traits of advanced lines and commercial checks. The highest grain yield was produced by the genotype BWS-78 (7708 kg ha-1) followed by EST-29/9 (6979 kg ha-1) although non-significant for each other. The high yielding genotype BWS-78 also took less number of days (124) to maturity, semi-dwarf plant height and comparatively better 1000-grain weight. However, maximum 1000-grain weight (45.3g) among the test genotypes was obtained by NIA-25/5 which was not significantly different than check variety T.D-1 (46.3g). Similarly, EST29/9 had tall-dwarf plant height, early maturity and comparatively higher 1000-grain weight (45.0g) and ranked as second highest grain yielding genotype but was not significantly different than NIA-28/4, D-H-6/6 and D-H-6/7. The newly selected genetically improved genotypes possesses early maturity will be further confirmed and could be grown under late planting conditions.
