“…The plant breeder, therefore adopt simple selection method on the basis of the phenotype of the characters which ultimately improves the genetic background of these traits. Similar results have been reported by Rathi et al (2010); Babu et al (2012); Sarawgi et al (2000), Gannamani (2001) and Sao (2002).…”

“…Highest GA as percent mean was exhibited alkali spreading value (92.84%) followed by gel consistency (55.01%) kernel breadth after cooking (38.83%) and amylose content (35.08%). Similar findings were also reported by Shivani & Reddy (2000), Iftekharuddaula et al (2001), Gannamani (2001), Sao (2002), Rathi et al, (2010) and Babu et al (2012). High heritability with high genetic advance as percent mean was observed for all the grain quality traits except for hulling percent and milling percent which indicated that expression of these traits are less influenced by environment and controlled by additive gene action (Panse, 1957).…”

“…Rice is food grain crop of global importance with special preference in Asian countries. Grain yield improvement is the prime objective of plant breeders for several decades but demand for good quality rice is also increased in current decade as living standard of people are being gradually improved (Rathi et al, 2010). Therefore, improvement of grain quality features of rice becomes the utmost objective next to yield enhancement and has become major concern in rice breeding programs to meet the consumer preference and market demand.…”

“…Rice varieties having good milling parameters, good appearance quality, good cooking and eating parameters, can be considered as superior grain quality rice variety which increases the total economic value of rice. Consumer preferences for good quality rice varied from one geographical region to another (Juliano & Perez CM, 1984;Rathi et al, 2010). In India, long grain specially Basmati varieties and fine or short slender grain varieties with intermediate amylose and alkali spreading value, intermediate gel consistency and high volume expansion of cooked rice is preferred.…”

The investigation was carried out to estimate the components of genetic variability and associated statistical parameters for grain quality traits of 215 indigenous rice landraces of Chhattisgarh, India. Substantial genetic variability among the all genotypes was observed for the characteristics under study. All the genotypes were showed highly significant differences for all the studied grain quality traits. Coefficient of variation ranges from 8.61% for hulling percentage to 45.01% for alkali spreading value. Negligible difference between genotypic coefficient of variation and phenotypic coefficient of variation was observed for all the traits. High heritability with high genetic advance as percent mean was observed for all the grain quality traits except for hulling percent and milling percent. These results indicated that direct selection based on phenotypic performance could be rewarding for all quality traits because they are less influenced by environment and mostly governed by additive gene action. It has been observed that sixty nine genotypes had short slender type grain characteristics whereas; forty seven genotypes have short bold type grains. Thirty genotypes showed more than 80% hulling percent, fifty six genotypes showed more than 70% milling percent and fourteen genotypes showed more than 65%

“…Kernel length is positively and highly correlated with the length/breadth ratio (r=0.4766) thus confirming the findings of Nirmaladevi et al, (2015); Kumar, 2015;Saifur-Rasheed et al(2002). The trait kernel breadth has a positive and significant association with kernel length after cooking (r =0.4297), kernel breadth after cooking (r=0.4336), linear elongation ratio (r= 0.4708) (Rathi, et al, 2010) and volume expansion (r=0.5328).…”

Association study and selection of best rice genotypes based on grain quality traits was experimented with 44 rice cultures. The study material comprised of 40 stabilised mutant lines of ADT 37 and ADT (R) 45 and four varieties. The grains with 11-13 per cent of moisture content were subjected for all grain quality estimation/quantification. It is observed that the amylose did not show any correlation with any of the milling properties as well the Alkali Spread Value. Protein has a negative correlation with Gel Consistency. Kernel breadth exhibited a negative correlation with most of the traits. Volume expansion has a good positive correlation with grain elongation after cooking. Upon comparison of selection indices viz., Multiplicative Index, Index Free of Weights and Parameters, Base Index, Classical index, Index based on the sum of Ranks and Index based on gains desired, the multiplicative index has given higher gains for most of the traits. However the index based on the sum of ranks was found to give good weightage to all the important traits. Hence the genotypes viz., ACM17006, ACM 18001, ACM18021, ACM18011, ACM18017 were found promising in this study based on the sum of ranks index.
