Genetic diversity of the thirty Mexican wheat (Triticum aestivum L.) genotypes were evaluated on the basis of ten different traits in Randomized Block Design during Rabi season, 2007 - 2008. These genotypes were grouped into six different clusters by using Mahalanobis D2 analysis. Cluster V had maximum number of (12) genotypes while, cluster I had only one genotypes. Distribution pattern of all the genotypes into various clusters showed the presence of considerable genetic divergence among the genotypes for most of the traits studied. Maximum generalized distances were observed between clusters I and VI. Yield per plant, gluten content (%) and plant height showed maximum contribution to the total genetic divergence. The genotypes present in cluster I and VI may be used as parents in hybridization programmes to develop high yielding wheat varieties.Keywords

The present field investigation on "bio-efficacy of azoxystrobin 23 per cent SC against anthracnose in mango was conducted at Fruit Research Farm, Imaliya, Department of Horticulture, JNKVV, Jabalpur (Madhya Pradesh) during Kharif season 2014, to estimated the bio-efficiency of used fungicide against Anthracnose (Colletotrichum gloeosporioides) by different doses and time interval of application. The present field experiment resulted that all the treatments showed significant effect in increasing the yield of mango, among all the treatments azoxystrobin 23 per cent SC @ 188g a.i./ha produced maximum yield (121.66 kg/plot). While, minimum yield was estimated in treatment comparison (Mancozeb 75% WP) a.i./ha (70kg/plot) after each spray of chemical followed by market sample azoxystrobin 23 per cent SC @125 a.i./ha (76kg/plot) and azoxystrobin 23 per cent SC @376 a.i./ha (72kg/plot).Keywords
