“…However, coordination between three plant-height traits and/or increases in stalk strength and elasticity might be most effective. Similar observations were made in a previous popcorn research (Li et al , 2008.…”

“…Several previous studies have also reported QTLs for PH, EH and TH at this bin locus (Austin et al 2001;Flint-Garcia et al 2003). In a previous study, major QTLs for PH, EH and TH were detected in the F 2:3 and BC 2 S 1 generations, with contributions of 12.2% to 31.4% (Li et al 2008). Beavis et al (1991) detected one PH QTL with a 34% contribution, which might be associated with ct1 and Sdw1, two plant-height related genes.…”

“…Low ear height and a high ratio of top height/plant height (TH:PH) can lower the plant center of gravity, and is considered important in maize breeding when evaluating stalk lodging. Significant correlations and complex genetic relationships between the plant-height traits were reported (Li et al , 2008. The multiple trait-version of composite interval mapping (CIM) proposed by Jiang and Zeng (1995) is robust and estimates parameters with precision.…”

QTL mapping for plant-height traits has not been hitherto reported in high-oil maize. A high-oil maize inbred 'GY220' was crossed with two dent maize inbreds ('8984' and '8622') to generate two connected F2:3 populations. Four plant-height traits were evaluated in 284 and 265 F2:3 families. Single-trait QTL mapping and multiple-trait joint QTL mapping was used to detect QTLs for the traits and the genetic relationship between plant height (PH) and two other plant-height traits. A total of 28 QTLs and 12 pairs of digenic interactions among detected QTLs for four traits were detected in the two F2:3 families. Only one marker was shared between the two populations. Joint analysis of PH with ear height (EH) and PH with top height (TH) detected 32 additional QTLs. Our results showed that QTL detection for PH was dependent on the genetic background of dent corn inbreds. Multiple-trait joint QTL analysis could increase the number of detected QTLs.

“…In contrast to common corn, popcorn plants generally have smaller, thinner and weaker stems; are very precocious in the maturation and drying of grains; produce tillers more often; have higher susceptibility to diseases and pests; are more prolific, i.e., have a greater number of ears per plant; and have fewer and narrower leaves and a small grain size (Li et al, 2008;Viegas Neto et al, 2012). Popcorn plants also have a less developed root system and suffer greater damage by attack from curcubit beetle worms (D. speciosa) and nematodes, which makes the plant more susceptible to lodging and desiccation (Li et al, 2008).…”

BACKGROUNDPopcorn is the most popular specialty maize and it makes a significant contribution to the Indian and global economies. Despite perfect exploration of heterosis in field corn, progress in popcorn breeding remains constrained due to its narrow genetic base, leading to a significant dependence on imports. In this study, 15 landrace‐ and population‐derived inbreds from temperate and tropical germplasm were crossed with five testers, which are the parents of superior popcorn hybrids, in a line × tester mating design.RESULTSSignificant variation was observed in popping quality and agronomic traits among crosses evaluated across three locations representing diverse maize‐based agro‐climatic zones in India. Additive genetic variance governed the traits related to popping quality, whereas dominance variance was responsible for the agronomic traits. In addition to significant heterosis specific to certain traits, we identified promising crosses that exhibited superior performance in both popping quality and grain yield (GY). The genotype + genotype × environment (GGE) biplot methodology identified PMI‐PC‐104 and PMI‐PC‐101 as the best discriminating testers for popping quality traits and Dpcl‐15‐90 for GY. Lines PMI‐PC‐205, PMI‐PC‐207, and PMI‐PC‐209 were the best general combiners for popping quality traits and GY. The heterotic groups identified based on GGE‐biplots and the magnitude, direction and stability of combining ability effects would serve in the development of competitive popcorn hybrids for a sustainable popcorn market.CONCLUSIONUsing the additive nature of popping quality traits and the dominant nature of GY, recurrent intrapopulation selection can be employed to derive desirable popping quality inbreds with high GY for genetic enhancement. Desirable popping quality alleles from novel germplasm can thus be combined with high‐yielding domestic elite inbreds to establish a sustainable popcorn breeding program. © 2024 Society of Chemical Industry.
