“…Castor oil has got huge industrial importance due to the presence of ricinoleic acid (up to 85%) which confers distinctive industrial properties to the oil (Anjani, 2012;Nagarajan et al, 2019). It is used as an efficient Genetic parameters, diversity and character association lubricant for high-speed engines and as an ingredient in soaps, shampoo, shoe polish, candles and ointments (Ranjitha et al, 2019;Gouri Shankar et al, 2010;Morris, 2004).…”

Castor is an important non-edible oilseed crop having huge industrial and export potential. It is used as an efficient lubricant for high-speed engines and as an ingredient in several commodities. There is a critical need to identify or to improve the germplasm lines with desirable characters. In the present study, 82 germplasm lines were evaluated in augmented design to estimate the genetic parameters viz., PCV, GCV, heritability and genetic advance as per cent of mean, principal component analysis and correlation studies. Results showed that the difference between PCV and GCV was low indicating less impact of environment on trait expression. Heritability (broad sense) and genetic advance as per cent of mean values were high for all the traits thus role of additive gene action is found important in governing the traits. Cluster analysis studies revealed that all the genotypes were grouped into eight clusters and cluster VIII documented the highest mean values for hundred seed weight and plant yield. The entries PRC-2 and PCS-337 recorded higher hundred seed weights of 56.5 and 48.6 g, respectively and in turn higher yield. These lines can be utilized as parents in the hybrid development programme for yield improvement. Correlation studies revealed that plant yield showed a significant positive association with all the characters except for days to 50% flowering. Thus selection for these traits viz., primary spike length, effective primary spike length, the number of effective spikes per plant, the number of capsules per spike and hundred seed weight will be advantageous in attaining higher yields.

“…Secara keseluruhan, dari semua karakter kuantitatif yang telah dihitung memiliki nilai KVF yang lebih besar dibandingkan nilai KVG. Menurut Ranjitha et al, (2019) nilai KVF yang lebih tinggi dibandingkan nilai KVG pada semua karakter menunjukkan bahwa keragaman karakter dipengaruhi oleh lingkungan. Nilai KVF didapatkan dari hasil perhitungan akar ragam fenotipe dibagi oleh rata-rata dari seluruh populasi.…”

“…Hence, the insight into the magnitude of variability present in a gene pool of a crop species is of utmost importance for castor genetic improvement. Literatures on castor diversity analysis are few and scarce (Anjani, 2010;Kanti et al, 2015;Senthilvel et al, 2017;Dapke et al, 2016;Ranjitha et al, 2019;Cherukupalli and Mukta, 2021). The study would offer immense value in generating information for castor yield improvement.…”

Diverse source of early genotypes is obligatory for breeding high yielding early castor (Ricinus communis L.) cultivars. One hundred and twenty-five medium duration genotypes including three checks were evaluated for the presence of genetic diversity and variability. Genetic distance, variance components and correlation coefficients were estimated for seven seed related quantitative traits. Significant genotypic differences were observed among the collections for these traits. High heritability and high genetic advance were noticed for seed length, seed breadth, Length/Breadth ratio, shelling percentage, 100 seed weight and seed yield per plant, thus mode of gene action reported was additive. Genetic diversity analysis based on dendrogram, phenogram and circular form grouped the entries into seven groups and it computed inter and intra cluster distance. Principal Component Analysis (PCA) revealed that the first three components cumulatively accounted for 72.57 per cent of the total variation. Seed yield per plant showed a significant association with shelling percentage and 100 seed weight. Also, direct effects were high and positive through seed breadth, Length/Breadth ratio and 100 seed weight. The promising genotypes identified (ICIRG 2272103 and RG 1673) and the information generated would be useful for breeding early/medium cultivars as well to understand the physiological mechanism related to earliness in castor.
