“…In a similar investigation the inheritance pattern of kernel length and cooked kernel elongation in the cross Taroari Basmati x RAU 3036, and Pusa Basmati 1121 x Chhatri was studied. From the data from the F 2 lines it was concluded that kernel length and kernel elongation ratio was controlled by one or two major genes and those were influenced by few modifier genes (Kumar et al, 2018).…”

The hybridization of Pusa Basmati 1 and IR 72 produced an aromatic, elongating, and non-aromatic, non-elongating mapping population for quality attributes in rice. In terms of other qualitative qualities, the parents also differed genetically, and their genetic distance was considerable. In this study 365 lines in the F6 population were examined for kernel dimensions, cooked kernel elongation ratio (CKER), alkali spreading value (ASV), and kernel dimensions both before and after cooking. The apparent amylose content of the sub-set of 110 F6 lines was also characterized. With the exception of kernel breadth and ASV, all features showed continuous and normal distribution, indicating quantitative inheritance. All of the characteristics, with the exception of ASV, showed transgressive segregation. High heritability findings suggest that the quality attributes in the F6 lines were genetically fixed. One-way analysis of variance (ANOVA) was used to evaluate four distinct hypotheses about the correlation of QTLs for quality attributes. The phenotypic variance explained by the QTLs was 45.68% for CKE-R, 38.63% for LAC, and 25.35% for L-BAC, indicating that the parent Pusa Basmati 1 was the source of the gene(s) controlling the inheritance of these traits.

Oryza sativa holds a unique position among domesticated crop species as it is one of the most important staple foods globally. Without rice, the day will not be fulfilled in most of the Asian countries. Requirement of rice for consumption is anticipated from 450 million tons in 2011 to about 490 million tons in 2020 and to around 650 million tons by 2050 globally. To meet the food demands, it has been estimated that 40 per cent more rice is needed to be produced by 2050 for the ever increasing population. Increasing incidences of both biotic and abiotic stresses under changing climate are the major constraints in rice production to meet the rapidly escalating population. Crop improvement in rice will not be completed lacking of grain quality analysis. Rice grain quality embraces storage, milling, market quality, cooking and eating quality and nutritive quality of grain. Demand for high quality rice has increased globally in recent years and continues to trend upward due to the taste preferences. Since, consumer demand in Asia and all over the world are diverse due to varied demographics and culture, defining uniform attributes to grain quality becomes more challenging. The Middle Eastern consumers highly prefer long grain, well milled rice with strong aroma while European consumers prefer long grain non aromatic rices. In Asia, Chinese consumers prefer semi-aromatic rice to pure aromatic rice. Cooked kernel elongation is the most important quality traits, which differentiate the highly valued basmati rice from other rice types. Kernel elongation after cooking is an important character of fine rice and the most rice consumers prefer lengthwise elongation.
