Textural property is one of the most important factors influencing the quality of northern-style Chinese steamed bread (CSB). We detected quantitative trait loci (QTLs) for the textural properties of CSB by using 184 recombinant inbred lines derived from a cross between two Chinese winter wheat (Triticum aestivum L.) varieties, Linmai6 and Tainong18. Eighteen putative QTLs were detected on 14 chromosomes: 1B, 1D, 2A, 2B, 2D, 3A, 3B, 4A, 4B, 5B, 6A, 6B, 7B, and 7D. Six textural quality traits, one QTL for hardness (QHa-4A), three QTLs for springiness (QSp-3B, QSp-4B, and QSp-5B), seven QTLs for cohesiveness (QCo-6A, QCo-7B.1, QCo-7B.2, QCo-3A, QCo-1D, QCo-2B.1, and QCo-2B.2), four QTLs for resilience (QRe-2D, QRe-2A, QRe-7D, and QRe-1B), two QTLs for gumminess (QGu-6B, and QGu-3B), and one QTL for chewiness (QCh-7D) were detected. The contributions of the QTLs ranged from 6.19% to 15.74%. The present study enhances understanding of the genetic basis for the textural properties of northern-style CSB and provides the basis for gene mapping of these traits.

In order to improve the nutritional value and quality of steamed bread, and promote the industrial development of the whole-grain food industry, a texture analyzer was used to study the effects of cultivars of whole foxtail millet flour (WFMF) on the texture of Chinese steamed bread (CSB). Orthogonal partial least squares discriminant analysis (OPLS-DA) was also conducted. The addition of different cultivars of WFMF significantly altered the height–diameter ratio, specific volume, hardness, cohesiveness, gumminess, and chewiness of CSB (p < 0.05). Large amounts of foxtail millet flour significantly increased the hardness, gumminess and chewiness of the bread (p < 0.05), and the bread height–diameter ratio, specific volume, cohesiveness and springiness significantly decreased (p < 0.05). We screened sensory evaluation, chewiness, specific volume, and hardness as the signature differences in the quality components according to the variable influence on the projection (VIP) values. OPLS-DA could distinguish the addition levels of different samples.

Investigation was conducted to evaluate 210 recombinant inbred lines (RILs) of bread wheat to identify Yr genes using SSR markers and response to stripe rust reaction. Recombinant inbred lines were screened under epiphytotic conditions and data in terms of per cent leaf area infected were recorded using Modified Cobb’s Scale. A total of seven Yr genes, namely Yr7, Yr18, Yr26, Yr29, Yr36, Yr47 and Yr53 were found to be linked to yellow rust resistance. Out of 40 Yr specific SSR markers, seven (Xgwm130 (Yr7), Xbarc 352 (Yr18), Xgwm 11 (Yr26), Xwmc 44 (Yr29), Xwmc 149 (Yr53), WKS1_I (Yr36) and Xcfb309 (Yr47) were found to be polymorphic in parental genotypes and RIL population indicating the presence or absence of Yr genes. Three RILs namely, 51, 52, 55 had largest number of resistant genes (4Yr genes) followed by six lines namely, RIL No. 20, 21, 23, 29, 39, 53 had 3Yr genes having disease score (0S). These RILs may be utilized for incorporation of specific Yr genes in well adapted genotypes for improvement of disease resistance in bread wheat.

Karnal bunt of wheat caused by Tilletia indica can be a hindrance to wheat trade as the fungal disease is known to affect the quality of the grain. As a breeding strategy, a set of eight near isogenics lines (NILs) and backcross derived recombinant inbred lines (micro-RILs) were developed in the background of PBW 343 and WH542 for Karnal bunt resistance over a period of time. The donor stocks resistant to Karnal bunt used in the study were ALDAN ‘ S’ / IAS 58, CMH 77.308, H567.7I, HD29, HP1531, W485 and their derived lines KBRL 22 and KBRL 57. Effective method for screening to Karnal bunt was standardized and used for identification of resistant lines across many seasons. Some of the identified lines evaluated for yield were found to be equivalent to the high yielding parents and the commercially grown check varieties. These developed lines will serve as a basic material for production of Karnal bunt free wheat.
