YIELD AND YIELD COMPONENTS WITH RELATION TO PLANT HEIGHT IN SEMI-DWARF WHEAT

Eighteen genotypes including two check varieties were compared for yield and yield components. In this yield comparison lines 04 and 08 had the highest grain yield per plot. The subsequent line which had higher grain yield was 06. The possible reasons for the highest grain yield in line 04 could be due to the longest spike length, the highest number of spikelets per spike, higher number of grains per spike, higher grain yield of main spike and higher grain weight. Correlations were calculated for pooled yield and yield components data of various genotypes. Plant height showed positive and highly significant correlation with spike length, number of spikelets per spike, number of grains per spike and main spike grain yield but no correlation with number of grains per spikelet. Main spike grain yield exhibited positive and highly significant correlation with plant height, spike length, number of spikelets per spike, number of grains per main spike and number of grains per spikelet.
