The objectives of the study were as follows: 1) to evaluate the GxExM for wheat genotypes;2) to predict yield performance and identify high stable wheat genotypes in different management practices;and 3) to make genotype-specific management and high performing genotype recommendations within and across agro-ecological regions. A diverse set of twenty-one genotypes was evaluated over three years (2012, 2013 and 2014) under two levels of crop management practices (CT and ZT) across three agro-ecological regions (BR, MP and PB) of India in replicated trials. Data were analyzed with SASGxE and RGxE programs using SAS and R programming languages, respectively. Across and within a location(s), the pattern of GxExM and GxMxY interactions (respectively) among univariate and multivariate stability statistics, grouping of genotypes in divisive clusters and estimates (with a prediction interval) of genotype varied in management practice CT and ZT. Across locations, the genotypes “Munal” and “HD-2967” were the best performers and high stable in CT and ZT, respectively. Genotypes “HD-2824” and “DPW-621-50”, and “Munal” may serve as diverse parents for developing high quality, climate smart, locally adapted genotypes for BR in CT and ZT, respectively. Genotypes “HD-2932”, “BAZ” and “JW-3288”, and “GW-322” and “HD-2967” are suitable for developing locally adapted stress tolerant genotypes for MP in management practices CT and ZT, respectively. Relatively small GxM and GxExM interactions in PB preclude in making definitive conclusions.

Objective Hemophilia A,an X-linked bleeding disorder,affecting 1 in 5 000 males is caused by heterogeneous mutations in factor Ⅷ *** mutation in intron 22 of F8C gene remains its leading *** aim of this study was to evaluate the frequency and distribution of the intron 22-inversion mutation in the patients and in the family members in the *** 29 hemophilia A patients from Jammu and Kashmir(20 severe,8 moderate and 1 mild) were analyzed for intron 22-inversion *** 11(38%) were positive for the distal type of inversion *** mutation was found in 9/20(45%) patients with severe factor Ⅷ deficiency and 2/8(25%) with moderate severity hemophilia A,whereas the patient with mild hemophilia A was found to be negative for inversion *** of twenty-six female relatives from 11 families of inversion mutation positive patients identified one mother and one sister from one family to be the carrier,suggesting its origin in the mother. Conclusion The present study confirms the intron-22 inversion mutation in F8C gene as the major cause of hemophilia A in the population from Jammu and Kashmir with a higher frequency of inversion mutation in sporadic cases compared to the familial cases.
