The study was conducted in Nasik and Ahmednagar districts of Maharashtra, during the year 2009-2010. The data were collected from 259 extension personnel viz., Agricultural Assistants (197), Agricultural Supervisors (39) and Agricultural Officers (23). The study revealed that more than half (54.05 per cent) of the extension personnel belonged to the category of medium knowledge level whereas, 28.57 per cent of respondents belonged to high knowledge level category and 17.37 per cent of the respondents belonged to the category of low knowledge level. The variables like education, in-service training participation in professional organizations, facilities available, job satisfaction, achievement motivation and information source use were found to be highly significant relationship with knowledge level.Keywords

The present study was conducted to ascertain the gene action and inheritance of yield and various yield-attributing traits and to screen the simple sequence repeat (SSR) markers for parental polymorphism in bitter gourd (Momordica charantia L.). Two contrasting parents (S-2 and Pusa Purvi) were used for hybridization. Parental polymorphism was analysed using 100 SSR markers. DNA amplicon of size around 150–250 bp in both the parents was obtained for the 10 polymorphic SSR markers. These were used to ascertain the hybridity of F1 progeny, from which the subsequent generations were developed. Generation mean analysis, ABCD scaling test and joint scaling test were performed using the observations from six generations (parent-1, parent-2, F1, F2, back cross 1 and back cross 2). The additive effect of the genes was predominant for the quantitative traits like fruit length, diameter, weight, etc. Duplicate epistasis was observed for the majority of traits. The yield per plant was positively correlated with fruit length, diameter, weight and fruit number per plant. Chi-square test revealed the monogenic inheritance of qualitative traits (fruit tubercles and ridgeness, and shape at apex), in which ‘conspicuous tubercles’, ‘discontinuous ridgeness’ and ‘acute fruit shape at apex’ were dominant. These results reveal the complexity and polygenic nature of the yield. The findings obtained from the present study can be used for yield improvement in the future. For this, the polymorphic SSRs identified can also be used in genetic diversity studies, DNA fingerprinting, genetic mapping, genomics analysis, etc.Keywords
