Eighty nine genotypes of vegetable cowpea collected from different parts of India were evaluated for yield and
yield-attributing traits for genetic variation, character association, cause-effect analysis and genetic diversity among
the genotypes through D2 statistics. High values of genotypic and phenotypic coefficient of variations, broad sense

A field experiment was conducted with 22 Brassica napus L. advanced lines at the experimental farm of Sher-e-Bangla Agricultural University, Dhaka to study the genetic variation among advanced lines of Brassica napus L. during November 2008 to March 2009. The genotypes were significantly different for all the characters studied except for days to 8...

... The present grouping of genotypes revealed that geographical distribution was not as important as g en e t i c di ve r si t y in s e le ct in g p a re nt s f o r hybridization, although it was a scale of genetic diversity. Lal (2017) demonstrated that parents' et al. choice for hybridization should be based on genetic rather than geographical diversity. Intra-and inter-cluster distances among different clusters ( ) revealed that cluster V had the Table 5 maximum intra-cluster distance. ...
... High contribution to the divergence by the characters like plant height, seed yield per plant, number of clusters per plant and days to 50% flowering, indicated that selection for divergent parents based on these characters woul be useful for successful breeding in cowpea. Similar finding was also observed by Lal (2017), Patel et al. et al. et al. et al. (2017) ...
The present experiment comprised of 46 cowpea genotypes to estimate genetic variability, interrelation among 13 quantitative characters and genetic divergence during 2020. High heritability coupled with highKharifgenetic advance as of mean was observed for the characters , seed yield per plant, number of per centviz.clusters per plant, number of pods per plant, plant height, days to 50% flowering and days to maturity. High phenotypic and genotypic coefficient of variation, heritability and high genetic advance as of mean per cent(GAM) were observed in seed yield per plant, number of clusters per plant, number of pods per plant and plant height. Seed yield per plant was found positively and significantly correlated with pods per plant, seeds per pod, pods per cluster, pod length and 100 seed weight. Path analysis revealed that number of seeds per pod, number of pods per plant and 100 seed weight would be selected as important towards seed yield charactersas they showed a high positive direct effect on seed yield. D analysis revealed that all the genotypes were 2grouped into seven distinct clusters. Cluster V had the maximum intra-cluster distance. The crossing among the genotypes of clusters V and VII, II and V, III and VI would result in novel recombinants as they showed high inter-cluster distance. Increased contribution to the divergence was found for the characters like plant height, seed yield per plant, number of clusters per plant and days to 50% flowering. Cluster V was found to be best performing for agronomic characters, followed by Cluster VI and Cluster III. Cluster II was best performing for nutritional value and earliness
Cabai merupakan salah satu tanaman hortikultura yang penting di Indonesia. Tanaman asli benua Amerika ini memiliki lebih dari 20 spesies liar dan lima spesies yang umum dibudidayakan, yakni Capsicum frutescens, Capsicum annuum, Capsicum chinense, Capsicum baccatum, dan Capsicum pubescens. Karakterisasi morfologi merupakan kegiatan untuk mengetahui karakter keseluruhan suatu tanaman mulai dari organ vegetatif hingga generatif. Karakterisasi pada organ bunga dan buah penting karena kedua organ tersebut mampu secara jelas membedakan jenis cabai. Tujuan penelitian ini untuk mengidentifikasi karakter morfologi bunga dan buah cabai, menentukan hubungan kekerabatannya, dan mengidentifikasi karakter yang berhubungan dengan potensi hasil cabai. Penelitian ini dilakukan di Pusat Inovasi Agroteknologi (PIAT) Universitas Gadjah Mada, Kalitirto, Berbah, Sleman, Daerah Istimewa Yogyakarta pada bulan Agustus 2019 hingga Maret 2020. Identifikasi dilakukan terhadap 20 aksesi yang disusun dalam Rancangan Acak Lengkap. Hasil penelitian menunjukkan bahwa 20 aksesi cabai memiliki karakter morfologi bunga dan buah yang beragam. Aksesi Chenzo 1 dengan Chenzo 2 merupakan aksesi yang memiliki kekerabatan paling dekat. Karakter morfologi yang berkorelasi dengan bobot total buah per tanaman sebagai potensi hasil cabai adalah diameter mahkota bunga, panjang, diameter, dan bobot per buah cabai.
