WebJan 1, 2000 · Yield components (ear length, kernel row number, number of kernels per row and ear diameter) also differed at the probability level of P=0.05. The strongest … WebThe ear IM grows and forms primordia, which become the spikelet pair meristems (SPMs), which in turn develop into spikelet meristems (SMs). Each spikelet meristem produces floral meristems (FMs), which determine the number of kernels in the ear. The kernel row number of maize is therefore determined by the number of SPMs in each ear.
WebOct 9, 2024 · On average, one ear of corn may contain about 800 kernels in 16 rows. Scientists found this by counting the number of kernels along each row. They believed that corn is evolved in this way to protect the seeds from birds. ... and then choose two or five ears of corn and count the number of kernels per ear, multiplying the row number by … WebAug 26, 2024 · The studied traits were mainly yield-related traits, such as ear length, kernel row number, kernel length, kernel width, and 100-kernel weight. The investigation results are shown in Table 1. Yield-related traits were significantly improved in several lines. For example, kernel width was significantly increased in OE-25, OE-34, and OE-57, and ...
WebMay 13, 2016 · The kernel number is a grain yield component and an important maize breeding goal. Ear length, kernel number per row and ear row number are highly correlated with the kernel number per ear, which eventually determines the ear weight and grain yield. In this study, two sets of F2:3 families developed from two bi-parental … WebCorn ears have an even number of kernel rows that can range from 12 to 22 rows (usually about 14-18 rows). Row number is primarily determined by genetics whereas kernel number per row (ear length) is strongly …
WebApr 6, 2024 · With the demand for maize (Zea mays L.) increasing worldwide, improving yield in agricultural production is critical (Shiferaw et al. 2011).Kernel row number (KRN) is an important factor that directly effects grain yield (Yang et al. 2015; Lu et al. 2011).During the domestication and improvement of maize, KRN is one of the most dramatic changes …
