Eight parents of aromatic rice were crossed in half diallel mating design without reciprocal including parents. The parents were evaluated for eleven different characters. Genetic analysis was done through Griffing’s Method II Model I. Analysis of variance revealed highly significant differences among parents and their crosses for all the characters. Combining ability analysis revealed that gca and sca variance were highly significant for most of the characters studied in F1 generation. Amongst the parental lines, Basmati Kasturi was a good general combiner for plant height at maturity, total number of spikelets per panicle, total number of filled grains per panicle and grain yield per plant in F1 generation while the most promising specific combiners for grain yield per plant were Basmati x Chakhao Angangba and Basmati Kasturi x Basmati 370.
The experiment comprises of 42 landraces accession of Manipur and were assessed for 28 quantitative morphological characters. These characters were evaluated by employing cluster and principle component analysis to obtain suitable parents. The analysis of variance revealed significant differences among the accessions for all the traits. The accession CAUCH 57 and CAUCH 69 has a maximum elucidation distance with the majority of accession collected indicating they are quite different from the rest of the collected landraces accession. Three broad clusters were formed in the dendogram produced by the morphological data. The principal component analysis of 28 morphological traits accounted for 80.47% of the total variation. The current study of maize landraces accounted for total eight principal components having eigen value greater than 1. The first principal component explained the highest 26.44% of the total variation. The results showed that the germplasm having a wide genetic diversity can be thus utilized for future breeding programme.
Eight genotypes consisting three Basmati varieties viz, Basmati Kasturi, Basmati 370 and Basmati with five Manipur scented rice landraces viz, Chakhao Poireiton, Chakhao, Chakhao Amubi, Ching Chakhao and Chakhao Angangba were crossed in 8X8 diallel fashion without recieprocal producing twenty eight F 1 hybrids and were evaluated to estimate mid parent heterosis for eleven yield contibuting characters. The best crosses which have the highest magnitude of mid-parent heterosis for grain yield per plant were Chakhao Poireiton x Chakhao Amubi(79.77), Chakhao Amubi x Ching Chakhao(79.11) and Chakhao Poireiton x Basmati(59.56). Basmati 370 x Ching Chakhao (-23.29)showed high magnitude of negative heterosis for plant height at maturity, Basmati x Ching Chakhao showed highest magnitude of positive heterosis for total number of spikelets per panicle (49.23) and total number of filled grains per panicle (65.77).
Social media is the use of Facebook, Youtube, Whatsapp, Blogs, Twitter, My Space and LinkedIn for the purpose of communication, sharing photos as well as videos (Acheaw and Larson, 2015;Balkrishna and Deshmuk, 2017;Thakur and Chander, 2018). However for the purpose of this study social media is captured within the use of internet through Facebook, Whatsapp, Youtube, Instagram, Telegram messenger as well as other Messengers for communication and sharing of information, innovations on latest technologies by sharing of photos and videos (Barau and Afrad, 2017). Teenagers and young adults have especially embraced these sites as a way to connect with their peers, share information, reinvent their personalities, and showcase their social lives. It is also astounding to accept as true that in little as two short decades, the evolution of the Internet and social media has taken place right before our eyes. It was only in 1991 that the World Wide Web became public,
