Genetic divergence in wheat (Triticum aestivum L.)

A field experiment was conducted during rabi season of 2003–2004 to study the genetic divergence in wheat (Triticum aestivum L). All the genotypes were grouped in 11 clusters. The highest number of genotypes were found in cluster I and II (10 each) followed by cluster III and IV (4 each) and cluster Vand VI (3 each). The maximum and minimum inter cluster distances were observed between cluster IV and cluster X (401.26) and cluster II and cluster IX (94.34), respectively. Highest cluster mean for seed yield per plant was found in cluster IX (22.46 g) and the lowest mean for this character was recorded in cluster VII (12.92), respectively. Leaf area of flag leaj (13.07) was found to contribute maximum towards total divergence. whereas number of grains spikeld (1.92) recorded the least to contribute total divergence.
