“…A dark chip colour seems to be a relatively dominant inherited character. This is in agreement with results found by De Jong & Tai (1991) and with results found in 4x .4x progenies (Cunningham & Stevenson, 1963) .…”

The parental effects on progenies from potato 4x .2x(FDR) crosses were analyzed to determine whether and to what extent selection criteria used for selecting tetraploid breeding lines have to be adjusted when selecting diploid breeding lines. For vine maturity and chip colour multiple regression analysis of progeny means on means of diploid and tetraploid parents revealed high coefficients of determination (R2 ) for both characters, indicating good predicting power of the performance of both diploid and tetraploid parents on the performance of their 4x .2x progenies . For vine maturity the multiple regression slope for the tetraploid parents was significantly larger than for the diploid parents, and progeny means were towards the tetraploid parents . This indicates that selection criteria for vine maturity may be less stringent at the diploid level . However, diploids may be earlier maturing than tetraploids and therefore selection criteria can better be similar at both ploidy levels . For chip colour, multiple regression slopes for diploid and tetraploid parents were similar and progeny means were towards the darkest coloured parent irrespective of its ploidy level . This indicates that selection of breeding lines for chip colour can be conducted similarly at both ploidy levels . 175

“…150 kg K 2 O /ha was due to absorption of higher percentage of fat during the process of frying. This result is in the line of Cunningham and Stevenson (1963) who reported that high French fry weight of low specific gravity and dry matter varieties could be due to the absorption by fried slices, of the frying oil. A positive correlation between specific gravity of potato tuber and weight after frying was observed by Tawfik et al, (2002).…”

An experiment was conducted at Divyapuri of Nawalparasi district in the western Terai during winter season 2008/09. There were 16 treatments consisting of two mulch levels (mulched and no mulch) as main plot, two varieties (Kufri Chipsona-1 and Kufri Chipsona-2) as sub plot and four levels of potash (0, 50, 100 and 150 kg K 2 O /ha) as sub-sub plot arranged in split-split plot design with four replications to evaluate the effect of these treatments on tuber production and their effect on quality of potato chips. The result showed that plant height, number of shoot per plant, dry matter accumulation, number and weight of tuber per plant and tuber yield were significantly higher in Kufri Chipsona-2 than in Kufri Chipsona-1. Lower reducing sugar and browning percent of chips and higher dry matter content and chips recovery were also recorded in Kufri Chipsona-2 compared to Kufri Chipsona-1. Simple economic analysis on gross return, net return and B/C ratio were higher in Kufri Chipsona-2. However, increasing levels of potash from 0-150 kg K 2 O /ha increased the dry matter accumulation, LAI, number and weight of tuber per plant. The result also showed that as the level of potash increased there was a decrease level of reducing sugar and browning of chips as well. On the other hand, higher potash levels increased the percentage of fat content and recovery of chips. Also increase in potash levels resulted to increase in gross return, net return, and B/C ratio. There was no effect of mulching levels on tuber yield and quality of chips recovery. Of the two varieties, Kufri Chipsona-2 with 100 kg K 2 O/ha was found suitable for tuber production and recovery of chips quality.

“…A qualidade dos chips é controlada geneticamente, o que propicia diferenças significativas entre as cultivares (Cunningham & Stevenson, 1963). Na obtenção de tubérculos com elevado teor de matéria seca e alta capacidade de produção de chips de cor clara, o primeiro critério é selecionar genótipos em relação a ambas características (Melo, 1999).…”

Resumo -Os objetivos deste trabalho foram determinar correlações inter e intragerações clonais, estimar herdabilidade quanto à cor de chips, teor de matéria seca e produção de batata, e suas implicações na seleção. Duzentos e cinqüenta clones de dez famílias foram escolhidos aleatoriamente de uma população de primeira geração clonal, destinada ao processamento de batatas chips, do programa de melhoramento genético de batata da Embrapa-Centro de Pesquisa Agropecuária de Clima Temperado. Os clones foram avaliados em segunda (G2), terceira (G3) e quarta (G4) gerações, respectivamente, no outono e primavera de 1999, e outono de 2000, em Pelotas, RS. Os coeficientes de correlação entre gerações e as estimativas de herdabilidade dentro das gerações clonais foram baixas em relação à cor de chips, baixas a moderadas quanto à matéria seca e incrementais com as gerações nos componentes de produção. Os coeficientes de correlação entre as características de qualidade e os componentes de produção dentro de cada geração foram baixos e, na maioria, não-significativos. As estimativas de herdabilidade dos dados conjuntos da G3 e G4 foram moderada, moderadamente alta e alta, respectivamente, em relação à cor de chips, teor de matéria seca e produção.Termos para indexação: Solanum tuberosum, clone, seleção, método de melhoramento. Correlations between and within generations and heritability of chips color, dry matter and yield in potatoesAbstract -The objectives of this work were to determine correlations between and within clonal generation, to estimate heritability for chips color, dry matter content and yield of potatoes, and their implications on selection. Two hundred and fifty clones of ten families were randomly chosen from a first clonal population, directed to chips processing, of the potato breeding program of EmbrapaCentro de Pesquisa Agropecuária de Clima Temperado. The clones were evaluated in second (G2), third (G3) and fourth (G4) generations during autumn and spring of 1999 and autumn of 2000, respectively, in Pelotas, RS. The coefficients of correlation between generations and the estimates of heritability within clonal generations were low for chips color, low to moderate for dry matter and incremental with generations for yield components. The coefficients of correlations between quality and yield component traits within each generation were low and, the majority, non significant. The estimates of heritability of joint G3 and G4 data analysis were moderate, moderately high and high, respectively, for chip color, dry matter content and yield.
