“…Implementation of an inbreeding program for the synthesis of new initial material in cumulative and recurrent selection involves the creation of special hybrid combinations with the participation of the best elite maize lines. A small number of basic elite inbreds allows to create a significant number of different hybrid combinations that respond differently to self-pollination, which is proved true by the results of other authors (Yong et al, 2019). According to our data, hybrid combinations with high combining ability on "grain yield" allow to obtain on their basis self-pollinated lines which are best on this trait.…”

“…The development of the basic breeding principles and methods for production self-pollinated maize lines rightfully belongs to G. H. Shull (Shull GH 1909) and E. M. East (East EM, 1936). Their researches had formed the basis of the standard method for obtaining maize lines, and eventually to the synthesis of modern maize hybrids (Dzyubetskyy et al, 2012;Jugenheimer, 1979;Parsons et al, 2020;Yong et al, 2019;Yu et al, 2020). It is the most common in breeding practice and uses the selection of the desired genotypes in all successive generations of self-pollination until the achievement of homozygous state.…”

Aim. The article presents the results of selection of Lancaster maize lines by the standard method during 2006–2019. Methods. The initial material was middle-ripe sister hybrid DK185×DK633-266 related to Lancaster (c103) germplasm. Its parental forms were the components of a number of hybrids listed in the State Register of Ukraine. Inbred DK633 (Lancaster C103 germplasm), closely related to inbred DK633-266 was taken as a control. The selection for a set of desirable features was made at each stage of self-pollination. Starting from the generation S3, self-pollinated families were crossed with testers from alternative germplasms to estimate their combining ability.esults. The maximum average grain yield of test crosses was recorded in 2011 – 10.97 t ha–1, the minimum – in dry year 2012 – 1.96 t ha–1. It was relatively low (4.45 t ha–1) in 2014; almost the same in 2010, 2015 and 2016 – 6.64, 6.87 and 6.54 t ha–1, respectively; slightly higher in 2009, 2013 and 2017 – 7.60, 7.77 and 7.71 t ha–1, respectively; and the largest in 2019 – 8.84 t ha–1and in 2018 – 9.16 t ha–1. The average grain moisture ranged from 11.8% in 2019 to 21.9% in 2009. Conclusion. A group of maize constant lines has been selected ((DK185×DK633-266) 4p12212111211, (DK185×DK633-266) 5p4221311211, (DK185×DK633-266) 5p4221311221, (DK185×DK633-266) 6p131121111, (DK185×DK633-266) 6p131121112, (DK185×DK633-266) 6p131121121 and (DK185×DK633-266) 6p2223111121)). The testcrosses of these lines exceeded in grain yield both testcrosses of inbred DK633 and standard hybrids by 0.5-1.5 t ha–1 at grain moisture at harvest lower by 2.0% or more. All of them have been included in crosses with the best testers of germplasms Reid, Iodent and Mix for synthesis of new perspective hybrids FAO 300-400.

“…To breed ideal hybrids with high GY (Yong et al, 2019), good quality (Machida et al, 2010) and strong resistance to biotic (Sibiya et al, 2013) and abiotic stresses (Makumbi et al, 2018), heterosis and combining ability have been analyzed for available germplasm with limited numbers of parental lines. Heterosis and combining ability are usually estimated by populations derived from special genetic designs, such as diallel (Griffing, 1956) and the NCD II (North Carolina design II) (Comstock and Robinson, 1948), which are two most powerful genetic designs for combining ability analysis and have been applied extensively.…”

Large sets of parental lines with available genotypic information can be shared and used in worldwide hybrid breeding programs through an open-source breeding strategy. Potential applications of the reported results in developing hybrid maize breeding strategies were also discussed.

“…Modified mass selection is plant-based selection, allowing breeders to control the pollination only for selected plants within a population [28]. As a result, this method may increase the frequencies of favorable alleles and maintain genetic variability [29,30]. Previous studies have reported the positive responses to modified mass selection for prolificacy [3], ear length [31], yield [32], and plant height [33] in different corn types.…”

The study aimed to improve the small-ear waxy corn populations for prolificacy, high total carotenoid content and resistance to downy mildew. Three cycles of modified mass selection were carried out for population improvement. Forty-four genotypes derived from eight C3 populations and six check varieties were evaluated for agronomic traits and yield at Khon Kaen and screened for downy mildew resistance in the rainy season 2020 at two experimental sites in Ban Phang district of Khon Kaen province. Fifty genotypes were clustered into six major groups based on color parameter (h°) and total ear number. Two selected groups (C and E) with two populations of small-ear waxy corn including Nei9008/BK-24-9-B and TY/TF-33-1-B were selected as they were resistant to downy mildew, prolific ears, and intense orange kernel color. Modified mass selection was effective for improvement of multiple traits in waxy corn.
